Chapter VI: Part 6

A small variety of the Wild Turkey, about 42 inches long. They breed in the tangled thickets in the higher portions of the southern half of Florida, laying from ten to sixteen eggs of a brighter and deeper buff color than the northern variety, and smaller; size 2.30 × 1.75. Their nests are generally lined with grasses and occasionally with feathers. The female sits very close when incubating and will not fly until almost trod upon, trusting to her variegated markings to conceal her from observation.

310c. RIO GRANDE TURKEY. _Meleagris gallopavo intermedia._

Range.--Lowlands of the southern parts of Texas and northern Mexico. A sub-species which differs slightly in plumage and not at all in nesting habits or eggs from the common Wild Turkey.

CURASSOWS AND GUANS. Family CRACIDÆ

311. CHACHALACA. _Ortalis vetula mccalli._

Range.--Eastern portions of Mexico, north to the Lower Rio Grande Valley in Texas.

A very peculiar grayish colored bird with a greenish gloss to the back, and a long, broad tail, quite long legs, and with the face and sides of the throat devoid of feathers. They are very abundant birds in some localities, and very noisy during the breeding season, their notes resembling a harsh trumpeting repetition of their name. They are ground inhabiting birds, but nest in low bushes. Their nests are made of sticks, twigs, leaves, or moss and are generally frail, flat structures only a few feet above the ground. During April, they lay from three to five buffy white eggs, the shell of which is very rough and hard. Size 2.25 × 1.55.

PIGEONS AND DOVES. Order XI. COLUMBÆ

Family COLUMBIDAE

Pigeons and doves are distributed throughout nearly every temperate and tropical country on the globe, nearly five hundred species being known, of which twelve occur within our limits. Their plumage is generally soft and subdued colors, the head small, the wings strong and the flight rapid.

312. BAND-TAILED PIGEON. _Columba fasciata fasciata._

Range.--The Rocky Mountains and westward to the Pacific, from British Columbia south to Mexico.

This large species may be generally recognized by the white crescent on the nape; it is about 15 inches in length. They nest abundantly on the mountain ranges, sometimes in large flocks, and again, only a few pairs together. Their nests are rude platforms of sticks and twigs either in bushes or in large trees in heavily wooded districts. The two eggs which are laid during May or June are pure white in color, and like those of all the pigeons, equally rounded at each end. Size 1.55 × 1.10.

312a. VIOSCA'S PIGEON. _Columba fasciata vioscæ._

Range.--Southern Lower California. This is a paler variety of the preceding species and is not noticeably different in its habits, nesting or eggs.

313. RED-BILLED PIGEON. _Columba flavirostris._

Range.--Mexico and Central America, north to southern Texas, Arizona and New Mexico.

This species, characterized by its red bill, purplish colored head, neck and breast and absence of iridescent markings, is abundant in the valley of the Lower Rio Grande, where they build their frail nests in thickets and low bushes, and during May and June lay their white eggs. Size of eggs, 1.55 × 1.05.

314. WHITE-CROWNED PIGEON. _Columba leucocephala._

Range.--Resident of the West Indies; in summer, found on the Florida Keys. This species, which can be identified by its white crown, nests in trees or mangroves on certain of the Florida Keys, laying its two white eggs on its rude platform of sticks and twigs. Size of eggs 1.40 × 1.05. Nests in April and May.

314.1. SCALED PIGEON. _Columba squamosa._

A West Indian species, a single specimen of which was taken at Key West, Florida.

A dark colored species, with purplish head, neck and breast; named from the scaly appearance of the iridescent feathers on the sides of the neck.

Page 193

315. PASSENGER PIGEON. _Ectopistes migratorius._

Range.--Formerly, North America east of the Rockies; casually seen in the upper Mississippi Valley, now extinct.

A handsome species (see frontispiece) with ruddy underparts, grayish upperparts and a long graduated tail. This species years ago found in flocks of thousands or millions, is now practically exterminated, chiefly by being hunted and trapped. A few pairs probably now nest in the interior, from northern United States to Hudson Bay. Their nests are very rude, frail platforms of twigs, on which two white eggs are laid, they being longer and narrower, comparatively, than those of other species. Size of eggs, 1.50 × 1.02. Data.--Southwest shore of Lake Manitoba, June 1, 1891. Nest of twigs in an aspen tree.

316. Mourning Dove. _Zenaidura macroura carolinensis._

Range.--North America from New England, Manitoba and British Columbia, southward.

Now that the Passenger Pigeon has disappeared, this species becomes the only one found in the east, with the exception of the little Ground Dove in the South Atlantic and Gulf States. While, sometimes, small flocks of them nest in a community, they generally nest in companies of two or three pairs. Their nests are generally at a low elevation, in trees, bushes and often upon the ground. Their nests are made entirely of twigs and rootlets, and eggs may be found from early in April until the latter part of September, as they often raise two or three broods a season. The two eggs are white. Size 1.15 × .80. Data.--Refugio Co., Texas, May 3, 1899. Two eggs laid on the ground in a slight cradle of twigs. Collector, James J. Carroll.

Page 194

317. ZENAIDA DOVE. _Zenaida zenaida._

Range.--West Indies; in summer, on the Florida Keys, but not in great numbers.

This species is similar in size to the Mourning Dove, but it has a short and square tail, and the secondaries are tipped with white, and the underparts more ruddy. They generally nest upon the ground, but occasionally in small bushes, laying two white eggs a trifle larger than those of the preceding species. Size 1.20 × .90. The nests are made of grasses and twigs, on the ground under bushes.

Page 195

318. WHITE-FRONTED DOVE. _Leptotila fulviventris brachyptera._

Range.--Mexico and Central America north to southern Texas.

Slightly larger than the last, much paler below, with no black ear mark as in the two preceding species, and with the forehead whitish. They build their nests of sticks, grasses and weeds, and place them in tangled vines and thickets a few feet from the ground. Their two eggs, which are laid in May and June, have a creamy white or buffy color. Size 1.15 × .85. They cannot be called a common species within our borders.

319. WHITE-WINGED DOVE. _Melopelia asiatica._

Range.--Central America, Mexico and the southwestern border of the United States.

This species is 12 inches in length, has a black patch on the ear coverts, white tips to the greater and lesser coverts and some of the secondaries, and broad white tips to the outer tail feathers, which are black. This species is very abundant in some localities within our borders. Their nests are very frail platforms of twigs placed in trees or bushes or precariously suspended among tangled vines. Their two eggs are white or creamy white, and measure 1.15 × .85.

320. GROUND DOVE. _Columbigallina passerina terrestris._

Range.--South Atlantic and Gulf States to eastern Texas.

The Ground Doves are the smallest of the family, measuring but about 6.5 inches in length. Their nesting habits and eggs are exactly like those of the next to be described. They are very abundant, especially along the South Atlantic coast.

320a. MEXICAN GROUND DOVE. _Chæmepelia passerinus pallescens._

Range.--Border of the United States from Texas to southern California and southward.

This paler sub-species builds a nest of twigs and weeds, placing the flat structure either in low bushes or on the ground. Their two white eggs are laid during April to July, they sometimes rearing two broods a season. Size of eggs, .85 × .65.

320b. BERMUDA GROUND DOVE. _Chæmepelia passerina bermudiana._

Range.--Bermuda. Smaller and paler than the last; otherwise the same in nesting habits and eggs.

Page 196

321. INCA DOVE. _Scardafella inca._

Range.--Mexican border of the United States south to Central America and Lower California.

This handsome species is about the size of the last, but its tail is longer and graduated, consequently its length is greater, it being about 8 inches long. It is not an uncommon species along our Mexican border, but is not nearly as abundant as is the Ground Dove. It is often called "Scaled Dove" because of the blackish edges of nearly all its feathers. They build fairly compact nests of twigs, rootlets and weeds, these being placed in bushes at a low elevation. They are two in number and pure white. Size .85 × .65.

322. KEY WEST QUAIL DOVE. _Geotrygon chrysia._

Range.--West Indies, rarely found at Key West, although supposed to have been common there in Audubon's time. This species is of about the size of the Mourning Dove, has rusty colored upper parts, and is whitish below, the white below the eye being separated from that of the throat by a stripe of dusky from the base of the bill. They nest in trees, laying two buffy white eggs. Size 1.15 × .9O.

322.1. RUDDY QUAIL DOVE. _Geotrygon montana._

Range.--Central America, north to eastern Mexico and the West Indies; once taken at Key West. This species is similar to the last but has no white streak under the eye, and the underparts are buffy. Eggs, creamy white. Size 1.15 × .90.

323. BLUE-HEADED QUAIL DOVE. _Starnoenas cyanocephala._

Range.--Cuba, accidentally straying to Key West, but not in recent years.

It is a beautiful species, with a bright blue crown, black throat and stripe through the eye, separated by a white line under the eye. The rest of the plumage is of a brownish or rusty color. Eggs buffy white. Size 1.30 × 1.05.

VULTURES, HAWKS and OWLS. Order XII. RAPTORES

AMERICAN VULTURES. Family CATHARTIDAE

Vultures are peculiarly formed birds of prey, having a bare head and neck, a lengthened bill strongly hooked at the end for tearing flesh, and long, strong, broad wings upon which they float in the air for hours at a time without any visible flapping. They are scavengers and do great service to mankind by devouring dead animal matter, that, if allowed to remain, would soon taint the atmosphere. Their eyesight and sense of smell is very acute. They do not, except in very unusual cases, capture their prey, but feed upon that which has been killed or died of disease.

324. CALIFORNIA VULTURE. _Gymnogyps californianus._

Range.--Apparently now restricted to the coast ranges of California, casually inland to Arizona, and formerly to British Columbia.

This large bird, which weighs about 20 pounds, measures about 4 feet in length, and has an expanse of wings of about 10 feet. Its plumage is blackish with lengthened lanceolate feathers about the neck, and with the greater wing coverts broadly tipped with grayish white (in very old birds). The birds are very rare in their restricted range and are becoming scarcer each year, owing to their being shot and their nests robbed. While the eggs are very rarely found and only secured at a great risk, they are not as unobtainable as many suppose, as may be seen from the fact that one private collection contains no less than six perfect specimens of the eggs and as many mounted birds. These birds lay but a single egg, placing it generally in caves or recesses in the face of cliffs, hundreds of feet from the ground, and often in inaccessible locations. The eggs are of an ashy gray color and measure about 4.45 × 1.55.

Page 199

325. TURKEY VULTURE. _Cathartes aura septentrionalis._

Range.--America, from New Jersey on the Atlantic coast, Manitoba and British Columbia, south to southern South America, wintering in the southern half of the United States.

The plumage of this small Buzzard (length 30 inches) is blackish brown, the naked head being red. It is very common in the southern and central portions of its range, where it frequents the streets and door yards picking up any refuse that is edible. It is a very graceful bird while on the wing, and can readily be identified when at a distance from the fact that, when in flight, the tips of the wings curve upward. The two eggs which constitute a set are laid upon the ground between large rocks, in hollow stumps, under logs, or between the branching trunks of large trees, generally in large woods. They frequently nest in communities and again, only a single pair may be found in the woods. Its nesting season ranges from March until June in the different localities. The eggs are creamy or bluish white, spotted and blotched with shades of brown, and with fainter markings of lavender. Size 2.70 × 1.85.

326. BLACK VULTURE. _Catharista uruba._

Range.--More southerly than the preceding; north regularly to North Carolina and southern Illinois, and west to the Rocky Mountains.

This species is about the same size, or slightly smaller than the Turkey Vulture; its plumage is entirely black as is also the naked head, and bill. In the South Atlantic and Gulf States, the present species is even more abundant than the preceding, and might even be said to be partially domesticated. The nesting habits are the same as those of the Turkey Buzzard but their eggs average longer and the ground color is pale greenish or bluish white rather than creamy. They are spotted and blotched the same. Size 3.00 × 2.00.

KITES, HAWKS AND EAGLES. Family BUTEONIDÆ

The members of this family are chiefly diurnal; they get their living by preying upon smaller animals or birds. They have strong sharply hooked bills, powerful legs and feet armed with strong, curved and sharply pointed talons.

327. SWALLOW-TAILED KITE. _Elanoides forficatus._

Range.--Southern United States; casually north to New York and Manitoba.

This most beautiful Kite can never be mistaken for any other; its whole head, neck and underparts are snowy white, while the back, wings and tail are glossy blue black, the wings being very long and the tail long and deeply forked. The extreme length of the bird is 24 inches. As a rule nests of this bird are placed high up in the tallest trees; they are made of sticks, weeds and moss. Two eggs, or rarely three, constitute a full set. They are white or bluish white, spotted with brown. The one figured is an unusually handsome marked specimen in the collection of Mr. C. W. Crandall. Average size of eggs, 1.80 × 1.50. Data.--Yegna Creek bottoms, Texas, April 27, 1891. Two eggs. Nest of sticks and green moss, the same moss also being used for lining; in an elm tree 80 feet up.

328. White-tailed Kite. _Elanus leucurus._

Range.--Southern United States, north to the Carolinas, Illinois and middle California.

This species can be recognized by its light bluish gray mantle, black shoulders and white tail. It is a very active species, feeding upon insects and reptiles, and small birds and mammals. The nests of these species are placed in trees at quite an elevation from the ground, being made of sticks, weeds and leaves. The eggs are creamy white, profusely blotched and spotted with reddish brown and umber. Size 1.65 × 1.25. Data.--Los Angeles, Cal., April 9, 1896. Nest in fork of willows about 25 feet up. Made of willow twigs and weed stalks, lined with pieces of bark.

Page 202

329. MISSISSIPPI KITE. _Ictinia mississippiensis._

Range.--Southeastern United States, north to South Carolina and Illinois.

A small species (length 14 inches) with the head, neck, and underparts gray, and the back, wings and tail blackish, the tips of the secondaries being grayish. They live almost exclusively upon insects, such as grasshoppers, and small reptiles. They build their nests of sticks and weeds well up in tall trees. The eggs are two or three in number and normally bluish white, unmarked, but occasionally with very faint spots of pale brown. Size 1.65 × 1.25. Data.--Giddings, Texas, May 31, 1887. Nest of sticks and weeds, with green pecan leaves in the lining; placed in the top of a live oak sapling, 20 feet from the ground. Collector, J. A. Singley.

330. EVERGLADE KITE. _Rostrhamus sociabilis._

Range.--South America, north to southern Florida and Mexico.

This peculiar species has a long, slender, curved bill, blackish plumage, with white rump and bases of outer tail feather. They feed largely upon snails, both land and water varieties. They nest at a low elevation in bushes or under brush, often over the water. The nests are of sticks, weeds and leaves. The three eggs are light greenish white, spotted and splashed with chestnut brown. Size, 1.70 × 1.30. Nest in a custard apple tree, 6 feet from the ground, built of twigs, lined with small vine stems and willow leaves.

Page 203

Page 204

331. MARSH HAWK. _Circus hudsonius._

Range.--Whole of North America, very abundant in all sections.

The adult of this species is very light colored, and young birds of the first two years have a reddish brown coloration; in both plumages the species is easily identified by the white patch on the rump. They are, almost exclusively frequenters of fields and marshes, where they can most often be seen, towards dusk, swooping in broad curves near the ground, watching for field mice, which form the larger portion of their diet. Their nests are made in swampy ground, often in the middle of a large marsh, being placed on the ground in the centre of a hummock or clump of grass; it is generally well lined with grasses and often rushes. They lay from four to seven pale bluish white eggs, generally unmarked; size 1.80 × 1.40.

332. SHARP-SHINNED HAWK. _Accipiter velox._

Range.--Whole of North America, wintering in the United States and southward; breeds throughout its range, but most abundantly in northern United States and northward. This is one of the smallest of the hawks and in the adult plumage is a beautiful species, being barred below with light brown, and having a bluish slate back. It is a very spirited and daring bird and is one of the most destructive to small birds and young chickens. Its nest is a rude and sometimes very frail platform of twigs and leaves placed against the trunk of the tree at any height, but averaging, perhaps, fifteen feet. The eggs are bluish white, beautifully blotched and spotted with shades of brown.

Page 205

333. COOPER'S HAWK. _Accipiter cooperi._

Range.--Whole of temperate North America, breeding throughout its range.

Although larger (length 17 inches), the plumage of this species is almost exactly the same as that of the preceding. Like the last, this is also a destructive species. They construct their nests in the crotches of trees, generally at quite a height from the ground; the nest is made of sticks and twigs, and often lined with pieces of bark; occasionally an old Hawk's or Crow's nest is used by the birds. Their eggs are bluish white, unmarked or faintly spotted with pale brown.

334. GOSHAWK. _Astur atricapillus atricapillus._

Range.--Northern North America, south in winter to the northern parts of the United States.

This species is one of the largest, strongest and most audacious of American Hawks, frequently carrying off Grouse and poultry, the latter often in the presence of the owner. It is a handsome species in the adult plumage, with bluish gray upper parts, and light under parts, finely vermiculated with grayish and black shafts to the feathers. Length 23 inches. Their nests are placed well up in the tallest trees, usually in dense woods, the nests being of sticks lined with weeds and bark. The three or four eggs are bluish white, generally unmarked, but occasionally with faint spots of brown. Size 2.30 x 1.70.

Page 206

Page 207

334a. WESTERN GOSHAWK. _Astur atricapillus striatulus._

Range.--Western North America from Alaska to California, breeding chiefly north of the United States except in some of the higher ranges of the Pacific coast. This sub-species is darker, both above and below, than the American Goshawk. Its nesting habits and eggs are precisely the same. The eggs are quite variable in size.

335. HARRIS'S HAWK. _Parabuteo unicinctus harrisi._

Range.--Mexico and Central America, north to the Mexican border of the United States; very abundant in southern Texas.

This is a peculiar blackish species, with white rump, and chestnut shoulders and thighs. It is commonly met with in company with Caracaras, Turkey Buzzards and Black Vultures, feeding upon carrion. They also feed to an extent on small mammals and birds. Their nests are made of sticks, twigs and weeds, and placed in bushes or low trees. The three or four eggs are laid in April or May. They are dull white in color and generally unmarked, although often showing traces of pale brown spots. They are quite variable in size, averaging 2.10 x 1.65.

Page 208

337. RED-TAILED HAWK. _Buteo borealis borealis_.

This is one of the handsomest of the larger hawks, and is the best known in the east, where it is commonly, but wrongly, designated as "hen hawk", a name, however, which is indiscriminately applied to any bird that has talons and a hooked beak. The adult of this species is unmistakable because of its reddish brown tail; young birds are very frequently confounded with other species. Their food consists chiefly of small rodents, snakes and lizards, and only occasionally are poultry or birds taken. They nest in the tallest trees in large patches of woods, the nests being made of sticks, weeds, leaves and trash. The eggs number from two to four, and are white, sometimes heavily, and sometimes sparingly, blotched and spotted with various shades of brown. Size 2.35 x 1.80.

337a. KRIDER'S HAWK. _Buteo borealis krideri_.

Range.--Plains of the United States, north to Manitoba.

This sub-species is described as lighter on the underparts, which are almost immaculate. Its nesting habits and eggs are the same as those of the preceding.

337b. WESTERN RED-TAIL. _Buteo borealis calurus_.

Range.--Western North America, chiefly west of the Rocky Mountains.

This sub-species varies from the plumage of the eastern Red-tail, to a nearly uniform sooty above and below, with the dark red tail crossed by several bands; it is a generally darker variety than the Red-tail. Its nesting habits are the same and the eggs show the great variations in markings that are common to the eastern bird.

Page 209

337d. HARLAN'S HAWK. _Buteo borealis harlani._

Range.--Gulf States and southward, north to Kansas.

This dark sub-species is generally nearly uniform blackish, but sometimes is lighter or even white below. Its tail is rusty, mottled with blackish and white. Its nesting habits are the same and the eggs are not distinguishable from those of the other Red-tails.

339. RED-SHOULDERED HAWK. _Buteo lineatus lineatus._

Range.--North America, east of the Plains and from the southern parts of the British Provinces southward; abundant and breeding throughout its range.

This species is smaller than the Red-tailed and is not as powerfully built; length 19 inches. The adults are handsomely barred beneath with reddish brown, giving the entire underparts a ruddy color. Like the last species, they rarely feed upon poultry, confining their diet chiefly to mice, rats, frogs, reptiles, etc. These Hawks nest in the larger growths of timber, usually building their nests high above the ground. The nest is of sticks, and lined with leaves, weeds and pieces of bark. They lay three or four eggs with a white ground color, variously blotched and spotted, either sparingly or heavily, with different shades of brown. Size 2.15 × 1.75. Data.--Kalamazoo, Michigan, April 25, 1898. Nest about 40 feet up in an oak tree; made of sticks and twigs and lined with bark. Four eggs. Collector, J. C. Holmes.

339a. Florida Red-shouldered Hawk. _Buteo lineatus alleni._

Range.--Florida and the Gulf coast; north to South Carolina. The nesting habits of this paler sub-species are precisely like those of the last species.

Page 210

Page 211

339b. RED-BELLIED HAWK. _Buteo lineatus elegans._

Range.--Pacific coast from British Columbia south to Lower California, chiefly west of the Rockies.

This variety is similar to, but darker than lineatus, and the underparts are a uniform reddish brown, without barring. Their nests are like those of the Red-shouldered variety, and almost always placed high up in the largest trees. The eggs are very similar, but average lighter in markings. Size 2.15 × 1.70. Data.--Diego, Cal., April 13, 1897. Nest in a sycamore 20 feet from ground, made of sticks, leaves and feathers.

340. Zone-tailed Hawk. _Buteo abbreviatus._

Range.--Mexico and Central America, north to the Mexican border of the United States.

This species, which is 19 inches long, is wholly black with the exception of the tail, which is banded. Their nests are built in heavy woods, and preferably in trees along the bank of a stream. The nest is of the usual Hawk construction and the two to four eggs are white, faintly marked with pale chestnut. Data.--Marathon, Texas. Nest of sticks, lined with weeds and rabbit fur; on a horizontal branch of a cotton-wood tree, 30 feet up.

Page 212

341. SENNETT'S WHITE-TAILED HAWK. _Buteo albicaudatus sennetti._

Range.--Mexican border of the United States and southward.

A large, handsome Hawk which may be identified by its dark upper parts and white underparts and tail, the flanks and tail being lightly barred with grayish; the shoulders are chestnut. It is especially abundant in the southern parts of Texas, where it builds its nests of sticks and weeds, lined with grasses, leaves and moss. They nest in March and April, laying two, or rarely three, eggs which are a dull white, and generally immaculate, but occasionally faintly or sparingly spotted with brown. Size of eggs 2.25 × 1.80.

342. SWAINSON'S HAWK. _Buteo swainsoni._

Range.--Central and western North America, from the Mississippi Valley and Hudson Bay, to the Pacific coast, breeding throughout its range.

In the greater part of its range, this is the most abundant of the Hawk family. Its plumage is extremely variable, showing all the intergradations from a uniform sooty blackish to the typical adult plumage of a grayish above, and a white below, with a large breast patch of rich chestnut. Their nesting habits are as variable as their plumage. In some localities, they nest exclusively in trees, in others indifferently upon the ground or rocky ledges. The nest is the usual Hawk structure of sticks; the eggs are white, variously splashed and spotted with reddish brown and umber. Size 2.20 × 1.70. Data.--Stark Co., N. D., May 21, 1897. Nest of sticks, lined with weeds in an ash tree. Collector, Roy Dodd.

Page 213

343. BROAD-WINGED HAWK. _Buteo platypterus._

Range.--North America, east of the Plains, and from the British Provinces southward.

A medium sized species, about 16 inches in length, and with a short tail and broad rounded wings; adults have the underparts handsomely barred with brown. Their nests are usually built in large trees, but generally placed against the trunk in the crotch of some of the lower branches. It is made of sticks and almost invariably lined with bark. The two to four eggs are of a grayish white color, marked with chestnut, brown and stone gray; size 1.90 × 1.55. Data.--Worcester, Mass., May 16, 1895. Nest about 20 feet up in a large chestnut tree. The birds continually circled overhead, their weird cries sounding like the creaking of branches. Collector, A. J. White.

344. SHORT-TAILED HAWK. _Buteo brachyurus._

Range.--A tropical species, which occurs north to the Mexican border and regularly to southern Florida, where it breeds in the large cypress swamps. Its eggs are pale greenish white, sparingly spotted with brown, chiefly at the large end. Size 2.15 × 1.60.

345. MEXICAN BLACK HAWK. _Urubitinga anthracina._

Range.--Mexican border of the United States and southward.

A coal black species about 22 inches in length, distinguished by the white tip, and broad white band across the tail about midway. This is one of the least abundant of the Mexican species that cross the border. They are shy birds and build their nests in the tallest trees in remote woods. Their two or three eggs are grayish white, faintly spotted with pale brown; size 2.25 × 1.80. Data.--Los Angeles County, Cal., April 6, 1889. Nest of sticks, lined with bark and leaves; 45 feet up in a sycamore tree. Collector, R. B. Chapman.

Page 214

346. MEXICAN GOSHAWK. _Asturina plagiata._

Range.--Mexico, north to the border of the United States.

A beautiful, medium sized Hawk (17 inches long), slaty gray above, white below, numerously barred with grayish; tail black, crossed by several white bars. These are graceful and active birds, feeding largely upon small rodents, and occasionally small birds. They nest in the top of tall trees, laying two or three greenish white, unmarked eggs; size 1.95 x 1.60. Data.--Santa Cruz River, Arizona, June 3, 1902. Nest in the fork of a mesquite tree about forty feet from the ground; made of large sticks, lined with smaller ones and leaves. Three eggs. Collector, O. W. Howard.

347a. ROUGH-LEGGED HAWK. _Archibuteo lagopus sancti-johannis._

Range.--Northern North America, breeding chiefly north of our borders and wintering south to the middle portions of the United States.

The Rough-legs are large, heavily built birds of prey, specially characterized by the completely feathered legs. The present species is 22 inches long, and in the normal plumage has a whitish head, neck, breast and tail, the former being streaked and the latter barred with blackish; the remainder of the upper and underparts are blackish brown. Their nests are usually placed in trees, and less often on the ground than those of the next species. These Rough-legs are very irregularly distributed, and are nowhere as common as the next. While the greater number nest north of the United States, it is very probable that a great many nest on the higher ranges within our borders. The species is often taken in summer, even in Massachusetts. They lay three eggs of a bluish white color, boldly splashed with dark brown; size 2.25 x 1.75.

Page 215

348. FERRUGINOUS ROUGH-LEG. _Archibuteo ferrugineus._

Range.--North America, west of the Mississippi, breeding from the latitude of Colorado north to the Saskatchewan region.

This species nests very abundantly along our northern states, particularly in Dakota. It is a larger bird than the preceding and can easily be told by its reddish coloration, particularly on the shoulders and tibia. While in some localities they nest only in trees, the greater number appear to build their nests on the ground or rocky ledges, making a large heap of sticks, weeds and grass. Their three or four eggs are white, beautifully spotted and blotched, in endless variety, with various shades of brown. Size 2.60 x 2.00. Data.--Stark Co., N. D., April 29, 1900. Nest built of coarse sticks on a clay butte.

349. GOLDEN EAGLE. _Aquila chrysætos._

Range.--North America, west of the Mississippi; most abundant in the Rockies and along the Pacific coast ranges.

This magnificent bird, which is even more powerful than the Bald Eagle, measures about 34 inches long, and spreads about 7 feet. Its plumage is a rich brownish black, very old birds being golden brown on the nape. They can be distinguished in all plumages from the Bald Eagle by the completely feathered tarsus. They build their nests in the tops of the tallest trees in the wild, mountainous country of the west, and more rarely upon ledges of the cliffs. The nests are made of large sticks, lined with smaller ones and leaves and weeds. Their eggs are the most handsome of the Raptores, being white in color, and blotched, splashed, spotted and specked with light brown and clouded with gray or lilac, of course varying endlessly in pattern and intensity. Size 2.90 x 2.50. Data.--Monterey Co., Cal., May 3, 1888. Three eggs. Nest of sticks, lined with pine needles, in a pine tree, 50 feet up.

351. GRAY SEA EAGLE. _Haliæetus albicilla._

A common species on the sea coasts of Europe; straggling to southern Greenland, where it nests upon the rocky cliffs.

352. BALD EAGLE. _Haliæetus leucocephalus leucocephalus._

Range.--Whole of North America; most abundant on the Atlantic coast; breeds throughout its range. This large white-headed and white-tailed species is abundant in sufficiently wild localities along the Atlantic coast. It only attains the white head and tail when three years old, the first two years, being blackish. It is about 34 inches in length and expands about seven feet, never over eight feet, and only birds of the second year (when they are larger than the adults) ever approach this expanse. Their food consists of fish (which they sometimes capture themselves, but more often take from the Osprey), carrion, and Ducks, which they catch in flight. Their nests are massive structures of sticks, in the tops of tall trees. They very rarely lay more than two eggs, which are white. Size 2.75 x 2.10. Data.--Mt. Pleasant, S. C., nest in top of a pine, 105 feet from the ground; made of large sticks and lined with Spanish moss.

352a. NORTHERN BALD EAGLE.--_Haliæetus leucocephalus alascanus._

Range.--Alaska. This sub-species averages slightly larger than the Bald Eagle, but never exceeds the largest dimensions of that species. Its nesting habits and eggs are the same, except that it more often builds its nests on rocky cliffs than does the Bald Eagle. The eggs are laid in February and March.

FALCONS AND CARACARAS

Family FALCONDIDAE

353. WHITE GYRFALCON. _Falco islandus._

Range.--Arctic regions; south in winter casually to northern United States, chiefly on the coast.

Gyrfalcons are large, strong, active and fearless birds, about 23 inches in length. Their food consists chiefly of hares, Ducks and Waders which abound in the far north. The present species is snowy white, more or less barred with blackish brown on the back and wings and with a few marks on the breast. They nest upon the ledges of high cliffs, laying three or four eggs of a buffy color, blotched and finely specked with reddish brown, this color often concealing the ground color. Size of eggs, 2.30 × 1.80. In America, they nest in Greenland and the Arctic regions.

354. GRAY GYRFALCON. _Falco rusticolus rusticolus._

Range.--Arctic regions; south in winter to northern United States.

This species is of the size of the last but the plumage is largely gray, barred with dusky. They nest more abundantly in southern Greenland than do the preceding species. The nesting habits and eggs do not differ.

354a. Gyrfalcon. _Falco rusticolus gyrfalco._

Range.--Arctic regions; south casually to Long Island.

This sub-species is hardly to be distinguished from the preceding; its nesting habits and eggs are identical, the nests being of sticks, lined with weeds and feathers and placed upon the most inaccessible ledges of cliffs.

Page 219

354b. BLACK GYRFALCON. _Falco rusticolus obsoletus._

Range.--Labrador; south casually, in winter, to Long Island.

A slightly darker variety. Eggs indistinguishable. Data.--Ungava coast, Labrador, May 25, 1900. Nest a heap of seaweed and feathers on sea cliff, containing three eggs.

355. PRAIRIE FALCON. _Falcon mexicanus._

Range.--United States west of the Mississippi, and from Dakota and Washington southward to Mexico.

This species abounds in suitable localities, generally placing its nests upon rocky ledges and cliffs, and sometimes trees, generally upon the banks of some stream. The nests are masses of sticks, lined with weeds and grasses. The three or four eggs have a reddish buff ground color, and are thickly sprinkled and blotched with reddish buff brown and chestnut; size 2.05 × 1.60.

356a. Duck Hawk. _Falco peregrinus anatum._

Range.--Whole of North America, breeding locally, chiefly in mountainous regions, throughout its range.

This beautiful species, characterized by its black moustache, is the most graceful, fearless, and swiftest of the Falcons, striking down birds of several times its own weight, such as some of the larger Ducks. It breeds quite abundantly on the Pacific coast and in certain localities in the Dakotas, laying its eggs on the rocky ledges. Their eggs are similar to those of the Prairie Falcon, but are darker and brighter, in fact they are the darkest, brightest marked, and most beautiful of Falcon eggs; size 2.05 × 1.55.

Page 220

356b. PEALE'S FALCON. _Falco peregrinus pealei._

Range.--Pacific coast from northern United States north to Alaska.

A darker form of the preceding, such as occurs in this section with a great many other birds. The nesting habits and the eggs are precisely like those of the Duck Hawk.

357. Pigeon Hawk. _Falco columbarius columbarius._

Range.--North America, breeding chiefly north of the United States except in some of the higher ranges along our northern border. A small Falcon, about 11 inches long, often confused with the Sharp-shinned Hawk, but much darker and a more stoutly built bird. It is a daring species, often attacking birds larger than itself; it also feeds on mice, grasshoppers, squirrels, etc. They generally build a nest of sticks in trees, deep in the woods; less often in natural cavities of dead trees; and sometimes on rocky ledges. Their four or five eggs have a brownish buff ground color, heavily blotched with brown and chestnut. Size 1.50 × 1.22.

357a. BLACK PIGEON HAWK. _Falco columbarius suckleyi._

Range.--Pacific coast from northern United States north to Alaska.

Very similar in appearance to the preceding, but much darker, both above and below. Its nesting habits and eggs will not differ in any manner from those of the Pigeon Hawk.

357b. RICHARDSON'S PIGEON HAWK. _Falco columbarius richardsoni._

Range.--Interior of North America from the Mississippi to the Rockies and from Mexico to the Saskatchewan.

This species is similar to the Pigeon Hawk, but is paler both above and below, and the tail bars are more numerous and white. Their nesting habits are the same as those of the preceding species, they either building in hollow trees, or making a rude nest of sticks and twigs in the tops of trees. The eggs have a creamy ground and are sprinkled with dots and blotches of various shades of brown. Size 1.60 × 1.23. The egg figured is one of a beautiful set of four in the collection of Mr. C. W. Crandall.

Page 221

358.1 MERLIN. _Falco æsalon._

This common European species was once accidentally taken in southern Greenland. Their eggs are generally laid on the ground on cliffs or banks.

359. APLOMADO FALCON. _Falco fusco-cærulescens._

Range.--Tropical America north to Mexican boundary of the United States.

This handsome and strikingly marked Falcon is found in limited numbers within the United States, but south is common and widely distributed. They nest at a low elevation, in bushes or small trees, making their rude nests of twigs, lined with a few grasses. They lay three, and sometimes four, eggs which have a creamy white ground color, finely dotted with cinnamon, and with heavy blotches of brown. Size 1.75 × 1.30.

359.1. KESTREL. _Falco tinnunculus._

Range.--Whole of Europe; accidental on the coast of Massachusetts.

This species is very similar in size and coloration to the American Sparrow Hawk. They are much more abundant than the Sparrow Hawk is in this country and frequently nest about houses, in hollow trees, on rafters of barns, or on ledges and embankments. Their eggs are of a reddish buff color, speckled and blotched with reddish brown, they being much darker than those of the American Sparrow Hawk.

360a. Desert Sparrow Hawk. _Falco sparverius phalæna._

Range.--Western United States from British Columbia south to Mexico.

This variety is slightly larger and paler than the eastern form. There are no differences in the identification of the two varieties.

Page 222

360. SPARROW HAWK. _Falco sparverius._

Range.--North America, east of the Rocky Mountains and north to Hudson Bay; winters from the middle portions of the United States, southward.

This beautiful little Falcon is the smallest of the American Hawks, being only 10 inches in length. They are very abundant in the east, nesting anywhere in cavities in trees, either in woods or open fields. The eggs are generally deposited upon the bottom of the cavity with no lining; they are creamy or yellowish buff in color, sprinkled, spotted or blotched in endless variety, with reddish brown. Size 1.35 × 1.10. These birds are very noisy, especially when the young are learning to fly, uttering a loud, tinkling, "killy, killy, killy." They have a very amiable disposition, and frequently nest harmoniously in the same tree with other birds, such as Flickers and Robins.

360b. ST. LUCAS SPARROW HAWK. _Falco sparverius peninsularis._

Range.--Lower California.

This variety is smaller than the eastern, and even paler than the western form. Eggs identical with eastern specimens.

361. CUBAN SPARROW HAWK. _Falco sparveroides._

A darker colored West Indian form, whose habits and nesting do not vary from those of the common Sparrow Hawk; casually taken in Florida.

Page 223

Page 224

362. Audubon Caracara. _Polyborus cheriway._

Range.--Southern border of the United States south to South America.

A strikingly marked blackish and whitish species, much barred on the fore back and the breast, with the head and throat largely white, except for a black and somewhat crested crown. They are numerous in southern Texas and also in the interior of southern Florida, where they are resident. They build bulky, but shabby nests of sticks, weeds and grass, piled into a promiscuous heap, generally located in bushes or low trees. Their two or three eggs have a ground color varying from buff to bright cinnamon, and are dotted and blotched with all shades of brown and umber. On the whole, these eggs show a greater diversity of markings and ground color than those of any other species. Size 2.50 × 1.80.

363. GUADALUPE CARACARA. _Polyborus lutosus._

Range.--Guadalupe Island and others off Lower California.

This species is somewhat like the preceding, but the plumage is duller, and the coloration more uniform. Their nesting habits and eggs do not vary essentially from those of Audubon Caracara. Mr. John Lewis Childs has a set of two eggs taken June 8, 1896, on Santa Anita Island, by Coolidge and Miller. The nest was made of sticks and situated in a giant cactus. The eggs are slightly brighter and more clearly marked than any of cheriway that I have ever seen.

Page 225

OSPREY. Family Pandionidae

364. OSPREY. _Pandion haliætus carolinensis._

Range.--Whole of temperate America from the Arctic circle south to the equator, most abundant along the sea coasts.

Real old birds have the head whiter, and less white edging to the back feathers, than do the young. Feet very strong, and very hard and rough, perfectly adapted to grasping slippery fish; outer toe can be used equally as well, either in front or behind, when perching or grasping their prey.

Probably this great fisherman is as well known from one end of the country to the other as any of our wild birds. He is protected by law in a great many states and by custom in nearly all localities where they breed. It is one of the pleasantest sights along the coast to watch a number of these great birds as they soar at an elevation above the water, watching for fish to come near the surface, when, with folded wings, the bird speeds downward and plunges into the water, rarely missing his prey. In many localities they are very tame and nest in the vicinity of houses, sometimes even in the yard. Their nests are platforms of sticks, which, being used year after year and constantly added to, become of enormous proportions. They lay two or three eggs of a bright creamy color, handsomely blotched with bright chestnut brown. They show a great diversity of size as well as markings, but average 2.40 × 1.80.

BARN OWLS. Family Alucondidae

365. BARN OWL. _Aluco pratincola._

Range.--Chiefly in the southern parts of the United States; north casually to Massachusetts, Minnesota and Washington.

This is one of the lightest colored of the Owls; it has a long, peculiarly hooded face, from which it gets the name of "Monkey-faced Owl." Its plumage is yellowish buff, specked and barred lightly with blackish.

It nests usually in hollow cavities of trees, but appears to have no objections to barns, holes in banks, or anywhere it can find a concealed crevice in which to deposit its four to six pure white eggs; size 1.70 × 1.30.

HORNED OWL. Family Strigidae

366. LONG-EARED OWL. _Asio wilsonianus._

Range.--North America, breeding from the southern parts of British America, southward.

This species is 15 inches in length; it can easily be separated from any other species by its long ear tufts, brownish face, and barred underparts. Their food consists almost entirely of small rodents, which they catch at night. Most of their nests are found in trees, they generally using old Crow's or Hawk's nests. They also, in some localities, nest in hollow trees, or in crevices among rocks. They lay from four to seven pure white eggs; size 1.55 × 1.35.

Page 228

Page 229

367. SHORT-EARED OWL. _Asio flammeus._

Range.--Whole of North America, breeding from the middle portions of the United States northward, and wintering in the United States.

This species is of the size of the last, but is paler, has very short ear tufts, and is streaked beneath. Its habits are the same except that it frequently hunts, over the marshes and meadows, on dark days and towards dusk.

Their four to seven pure white eggs are laid upon the ground in marshy places, sometimes upon a lining of sticks and weeds, and are generally under a bush, or close to an old log. Size of eggs 1.55 × 1.25.

368. BARRED OWL. _Strix varia varia._

Range.--Eastern North America, from the British Provinces, southward; west to the Rockies.

This species is the most common of the large owls, and can be distinguished by its mottled and barred gray and white plumage, and lack of ear tufts; length 20 inches. It is the bird commonly meant by the term "hoot owl", and being strictly nocturnal, is rarely seen flying in the day time, unless disturbed from its roosting place in the deep woods. Its food consists chiefly of rats, mice and frogs, and sometimes, but not often, poultry. It nests in the heart of large woods, generally in hollows of large trees, and less often in deserted Crow's nests. They lay from two to four pure white eggs, averaging considerably smaller than those of the Great Horned Owl; size 1.95 × 1.65.

368a. FLORIDA BARRED OWL. _Strix varia alleni._

Range.--Florida and the Gulf States; north to South Carolina.

Page 230

Page 231

368b. TEXAS BARRED OWL. _Strix varia albogilva._

Range.--Southern Texas.

A very similar but slightly paler variety than the Barred Owl, and with the toes bare, as in _alleni._ Eggs indistinguishable.

369. SPOTTED OWL. _Strix occidentalis occidentalis._

Range.--Western United States, from southern Oregon and Colorado, southward.

Similar to the Barred Owl, but spotted, instead of barred, on the back of head and neck, and much more extensively barred on the under parts. The nesting habits do not appear to differ in any respect from those of the eastern Barred Owl, and their eggs, which are from two to four in number, can not be distinguished from those of the latter species; size 2.05 × 1.80.

369a. NORTHERN SPOTTED Owl. _Strix occidentalis caurina._

Range.--Northwestern United States and British Columbia.

Similar to the preceding, but darker, both above and below; nesting the same, in hollow trees or in old Hawk's or Crow's nests. Eggs not distinguishable.

370. Great Gray Owl. _Scotiaptex nebulosa._

Range.--Northern North America; wintering regularly south to the northern border of the United States and casually farther.

This is the largest of American Owls, being about 26 inches in length; it does not weigh nearly as much, however, as the Great Horned or Snowy Owls, its plumage being very light and fluffy, and dark gray in color, mottled with white. The facial disc is very large, and the eyes are small and yellow, while those of the Barred Owl are large and blue black. They nest in heavily wooded districts, building their nests of sticks, chiefly in pine trees. The two to four white eggs are laid during May and June; size 2.15 × 1.70.

Page 232

370a. LAPP OWL. _Scotiaptex nebulosa lapponica._

A paler form of the Great Gray Owl, inhabiting the Arctic regions of the Old World; accidental on the coast of Alaska. Their nesting habits and eggs do not differ from those of the American bird.

371. RICHARDSON'S OWL. _Cryptoglaux funerea richardsoni._

Range.--Northern North America, breeding north of the United States; winters south to our border and casually farther.

This is a dark grayish and white bird, 10 inches in length, and without ear tufts. Breeds commonly in the extensively wooded districts of British America, chiefly in the northern parts. Their three or four white eggs are usually at the bottom of a cavity in a tree, but occasionally the birds build a rude nest of sticks and twigs, lined with leaves and placed in trees at a moderate height from the ground. Size of eggs, 1.25 × 1.05.

372. SAW-WHET OWL; ACADIAN OWL. _Cryptoglaux acadica acadica._

Range.--North America, breeding in the northern parts of the United States and in British America, and south in the Rockies to Mexico; winters south to the middle portions of the United States.

This small species (length 8 inches) is marked very similarly to the preceding, but the plumage is brown instead of gray. They normally nest in hollow trees, generally in deserted Woodpecker holes, in extensively wooded sections, and usually in mountainous country, especially in the United States. They have also been known to nest in bird boxes near farm houses and in old Crow's nests. During April or May, they lay from three to six white eggs. Size 1.20 × 1.00. They are quiet and chiefly nocturnal birds, not often seen, and may be found nesting in any of the northern states.

372a. NORTHWESTERN SAW-WHET OWL. _Cryptoglaux acadica scotiæa._

Range.--A dark variety found on the coast of British Columbia.

Page 233

373. SCREECH OWL. _Otus asio asio._

Range.--North America, east of the plains and from the southern British Provinces to Florida.

This well known species, which is often called "Little Horned Owl" because of its ear tufts is found either in the type form of some of its varieties in all parts of the United States. They have two color phases, the plumage being either a yellowish brown or gray, and black and white; these color phases are not dependent upon sex or locality, as often young or both phases are found in the same nest; the gray phase is the most abundant. They nest anywhere in hollow trees, being found very frequently in decayed stubs of apple trees. They also often nest in barns or other old buildings which are not frequented too freely. Their food consists chiefly of mice and meadow moles, with occasionally small birds. During April or May they lay their white eggs, the full complement of which is from five to eight. Size 1.35 × 1.20. The nesting habits of all the sub-species, as far as we can learn, are exactly like those of the eastern Screech Owl; the eggs cannot be distinguished, and in most cases, even the birds cannot be distinguished.

373a. FLORIDA SCREECH OWL. _Otus asio floridanus._

Range.--South Atlantic and Gulf coasts.

Slightly smaller and darker than asio. The eggs average slightly smaller. Size 1.30 × 1.15.

373b. Texas Screech Owl. _Otus asio mccalli._

Range.--Texas, and southward into Mexico. Very similar to floridanus.

373c. CALIFORNIA SCREECH OWL. _Otus asio bendirei._

Range.--Coast of California and Oregon. Size of, but darker than asio.

373d. KENNICOTT'S SCREECH OWL. _Otus asio kennicotti._

Range.--Pacific coast from Oregon to Alaska. This is the darkest of the Screech Owls and averages a trifle larger than the eastern form.

373e. ROCKY MOUNTAIN SCREECH OWL. _Otus asio maxwelliæ._

Range.--Foothills of the Rockies, from Colorado to Montana. This is the palest form of the Screech Owl. Of the same size as the last.

Page 234

373f. Mexican Screech Owl. _Otus asio cineraceus._

Range.--Western Mexico and southwestern border of the United States. A gray form with little or no buff, and more numerously barred below.

373g. AIKEN'S SCREECH Owl. _Otus asio aikeni._

Range.--El Paso County, Colorado. A gray form, with the dark markings coarser and more numerous than in any other.

373h. MACFARLANE'S SCREECH OWL. _Otus asio macfarlanei._

Range.--Northern border of the United States from Washington to Montana.

373.1. Spotted Screech Owl. _Otus trichopsis._

Range.--Mountains of southern Arizona, south into Mexico.

A grayish species, similar to asio, but paler and more finely barred beneath, and with whitish spots on the feathers of the foreback. The nesting habits and eggs are probably the same as those of the Screech Owl.

373.2. XANTUS'S SCREECH OWL. _Otus xantusi._

Range.--Southern Lower California.

A grayish species with the back and underparts finely vermiculated with reddish brown, and with streaks of darker. It is not likely that the habits or eggs of this species will be found to differ from those of the Screech Owl.

374. FLAMMULATED SCREECH OWL. _Otus flammeolus flammeolus._

Range.--Mountain ranges of Mexico, north to Colorado and west to California.

This species is smaller than asio, has shorter ear tufts, the plumage is much streaked and edged with rusty, and the toes are unfeathered to their base. They nest in hollow trees, generally using deserted Woodpecker holes. Their three or four eggs are white. Size 1.15 × .95. This species is uncommon in all parts of its range.

374a. DWARF SCREECH OWL. _Otus flammeolus idahœnsis._

Range.--Local in Idaho, eastern Washington and California.

This rare variety is smaller than the preceding and is considerably paler. Its eggs have not been described, but should be a trifle smaller than the last.

Page 235

375. GREAT HORNED OWL. _Bubo virginianus virginianus._

Range.--North America, east of the Plains and north to Labrador.
