DIVING BIRDS. Order I. PYGOPODES

GREBES. Family COLYMBIDÆ

Grebes are birds having a ducklike body, but with pointed bills. Their feet, too, are unlike those of the Ducks, each toe having its separate web, and having a broad flat nail. Their wings are very small for the size of the body, making it impossible for them to rise in flight from the land. They rise from the water by running a few yards along the surface until they have secured sufficient headway to allow them to launch themselves into the air. After having risen from the water their flight is very swift and strong. On land they are very awkward and can only progress by a series of awkward hops; they generally lie flat on their breasts, but occasionally stand up, supporting themselves upon their whole tarsus. Grebes, together with the Loons, are the most expert aquatic birds that we have, diving like a flash and swimming for an incredible distance under water.

Page 11

1. WESTERN GREBE. _Aechmophorus occidentalis_.

Range.--Western parts of North America, from southern Alaska southward; east to Minnesota and south in winter to the southern parts of the United States and Mexico. Breeds from the Dakotas and northern California northward. These are the largest of the American Grebes; owing to their unusually long necks, they are frequently called "Swan Grebes." They are very timid birds and conceal themselves in the rushes on the least suspicion of danger. At times, to escape observation, they will entirely submerge their body, leaving only their head and part of the long neck visible above the water. This Grebe cannot be mistaken for any other because of the long slender neck and the long pointed bill, which has a slight upward turn. They nest abundantly in the marshes of North Dakota and central Canada. Their nests are made of decayed rushes, and are built over the water, being fastened to the rushes so that the bottom of the nest rests in the water. The nesting season is at its height during the latter part of May. They lay from three to five eggs, the ground color of which is a pale blue; this color is, however, always concealed by a thin chalky deposit, and this latter is frequently stained to a dirty white. Size 2.40 × 1.55.

2. HOLBOELL'S GREBE. _Colymbus holboellii._

Range.--Throughout North America, breeding from northern United States northward and wintering from the middle to the southern portions of the United States. In regard to size this Grebe comes next to the Western, being 19 in. in length. This bird can be distinguished by the white cheeks and throat and the reddish brown foreneck. They breed abundantly in the far north placing their floating islands of decayed vegetation in the water in the midst of the marsh grass. They lay from three to six eggs of a dingy white color which have the stained surface common to Grebes eggs. Size 2.35 × 1.25.

Page 12

Page 13

3. HORNED GREBE. Colymbus auritus.

Range.--The whole of North America, breeding in the interior from North Dakota northwest; winters along the Gulf Coast. This species is one of the most beautiful of the Grebes, having in the breeding season buffy ear tufts, black cheeks and throat, and chestnut neck, breast and sides. They breed abundantly in the marshy flats of North Dakota and the interior of Canada. They build a typical Grebe's nest, a floating mass of decayed matter which stains the naturally white eggs to a dirty brown. The number of eggs varies from three to seven. Size 1.70 × 1.15. Data.--Devils Lake, N. Dakota, June 20, 1900. 6 eggs much stained. Nest floating in 4 ft. of water, a large mass of rotten rushes and weeds. Collector. James Smalley.

4. EARED GREBE. _Colymbus nigricollis californicus._

Range.--North America west of the Mississippi, breeding from Texas to Manitoba and wintering along the Pacific Coast of the United States and from Texas southward.

Eared Grebes differ from the preceding in having the entire neck blackish. They nest very abundantly throughout the west, in favorable localities, from Texas to Minnesota and Dakota. Their nests are constructed in the same manner as the preceding varieties and are located in similar localities. As do all the Grebes when leaving the nest, they cover the eggs with the damp rushes from around the base of the nest. This is probably for the purpose of assisting incubation during their absence, by the action of the sun's rays on the wet mass. As they are nearly always thus covered upon the approach of anyone, this may be done also as a protection from discovery. They lay from three to eight bluish white eggs with the usual chalky and discolored appearance. The breeding season is at its height early in June, or earlier, in the southern portion of its range. Size 1.75 × 1.20. Data.--Artesian, S. Dakota, June 21, 1899. Nest of rushes, floating in three feet of water. Large colony in a small lake. Collector, F. A. Patton.

5. MEXICAN GREBE. _Colymbus dominicus brachypterus._

Range.--Southern Texas and Lower California southward to South America, breeding throughout its range.

The Least Grebe is by far the smallest of the Grebes in this country, being but 10 in. in length; it can not be mistaken for any other, the Eared Grebe being the only species of this family found in the same localities during the summer. These little Grebes nest very abundantly along the Rio Grande Valley in Texas, the nesting season lasting from the latter part of May until well into December.

Their nests are floating piles of grass and weeds upon which they lay from three to five chalky white eggs, which are always discolored, sometimes to a deep chocolate hue. These eggs average a great deal darker in color than do any of the other Grebes. In a series of fifty sets fully half were a rich brown tint. Size 1.40 × .95.

6. PIED-BILLED GREBE. _Podilymbus podiceps._

Range.--From the British provinces southward to Argentine Republic, breeding locally throughout the northern portions of its range.

The Dabchick, as this bird is called, is the most evenly distributed bird of this family. It is nowhere especially abundant, nor is it, except in a very few localities, regarded as rare. Consequently it is the best known bird of the species. They do not congregate in such large numbers as the other Grebes during the nesting season, but one or more pairs may be found in almost any favorable locality. These birds render their floating nest a little more substantial than those of the preceding varieties by the addition of mud which they bring up from the bottom of the pond; this addition also tends to soil the eggs more, consequently the eggs of this bird are, as a general rule, browner than the other Grebes with the exception of the Least. The bird may always be known by the shape of its bill which is higher than it is broad, and in the summer is white with a black band across the middle. The throat is also black at this season. They lay from five to nine eggs commencing about the middle of May. Size 1.70 × 1.18.

LOONS. Family GAVIIDAE

Loons may be likened to gigantic Grebes from which they differ externally, chiefly in the full webbed foot instead of the individually webbed toes of the Grebe, and in the sharper, more pointed and spear-like bill. These birds are similar in their habits to the Grebes, except that their homes are generally more substantially built and are placed upon a solid foundation, generally upon an island in some inland lake.

Both Loons and Grebes are literally "Water witches," being practically, and in the case of Grebes, actually, born in the water and living in it ever afterwards. Loons are strong fliers, but like the Grebes, because of their small wings they must get their first impetus from the water in order to rise; in case there is any wind blowing they also make use of this by starting their flight against it. They are very peculiar birds and the expression "crazy as a loon" is not a fanciful one, being formed from their early morning and evening antics when two or more of them will race over the top of the water, up and down the lake, all the while uttering their demoniacal laughter. They vie with the Grebes in diving and disappear at the flash of a gun.

Page 18

7. LOON. _Gavia immer._

Range.--North America north of the Mexican boundary, breeding from the northern parts of the United States northward.

Unlike the Grebes, Loons do not build in colonies, generally not more than one, or at the most two pairs nesting on the same lake or pond; neither do they seek the marshy sloughs in which Grebes dwell, preferring the more open, clear bodies of water. The common Loon may be known in summer by the entirely black head and neck with the complete ribbon of black and white stripes encircling the lower neck and the narrower one which crosses the throat. The back is spotted with white. In some sections Loons build no nest, simply scooping a hollow out in the sand, while in other places they construct quite a large nest of sticks, moss and grasses. It is usually placed but a few feet from the waters edge, so that at the least suspicion the bird can slide off its eggs into the water, where it can cope with any enemy. The nests are nearly always concealed under the overhanging bushes that line the shore; the one shown in the full page illustration, however, was located upon the top of an old muskrat house. The two eggs which they lay are a very dark greenish brown in color, with black spots. Size 3.50 × 2.25. Data.--Lake Sunapee, N. H., June 28, 1895. Nest placed under the bushes at the waters edge. Made of rushes, weeds and grasses; a large structure nearly three feet in diameter. Collector, H. A. Collins.

8. YELLOW-BILLED LOON. _Gavia adamsi._

Range.--Northwestern North America, along the Arctic and northern Alaskan coasts.

The Yellow-billed Loon with the exception of its whitish or yellowish bill in place of the black, is practically otherwise indistinguishable from the common Loon. It averages somewhat larger in size. This is one of the most northerly breeding birds and it is only within a very few years that anything has been learned about the breeding habits. Their nesting habits and eggs are precisely like the preceding except that the latter average a little larger. Size 3.60 × 2.25.

9. BLACK-THROATED LOON. _Gavia arctica._.

Range.--From northern United States northward, breeding along the Arctic Coast.

This species can be easily separated from the Loon by the gray crown and white streaks down the back of the neck. Its size, too, is about five inches shorter. The nesting habits are the same as the Loons and the eggs have rather more of an olive tint besides having the majority of spots at the larger end. Size 3.10 × 2.00.

Page 19

10. PACIFIC LOON. _Gavia pacifica._

Range.--Western North America along the coast chiefly, breeding from Alaska south to British Columbia. In winter, south along the coast to Mexico.

This species differs from the Black-throated only in the tint of the head reflections. The habits are the same as those of the other members of the family. They lay two eggs of a greenish brown or greenish gray hue with black spots. Size 3.10 × 1.90. Data.--Yukon River, Alaska, June 28, 1902. Nest of rubbish on an island; found by a miner.

11. RED-THROATED LOON. _Gavia stellata._

Range.--Northern parts of North America, breeding from southern Canada northward in the interior on both coasts. South to the middle portions of the United States in winter.

This is the smallest of the Loon family, being twenty-five inches in length. In plumage it is wholly unlike any of the other members at all seasons of the year. In summer the back, head and neck are gray, the latter being striped with white. A large chestnut patch adorns the front of the lower part of the neck. In winter the back is spotted with white, whereas all the others are unspotted at this period. The nesting habits are identical with the other species; the ground color of the two eggs is also the same. Size 2.00 × 1.75.

PUFFINS, AUKS and MURRES. Family ALCIDÆ

Puffins, Auks and Murres are all sea birds and are only found inland when blown there by some severe storm of winter. At this season numbers of them are apt to lose their bearings and may sometimes be found with their feet frozen in some of our inland ponds. Puffins are heavily built birds in appearance, but are very active both on the wing and in the water. Their wings are much larger comparatively than those of the other members of this family, so they are enabled to perform evolutions in the air, which are withheld from the others. They stand upright on the sole of the foot and are able to walk quite easily on land. Puffins have very heavy and deep but thin bills, which are entirely unlike those of any other bird and often give then the name of Parrot Auks. Puffins, Auks and Murres are otherwise recognized by the presence of but three toes which are webbed.

Page 22

12. TUFTED PUFFIN. _Lunda cirrhata._

Range.--Pacific Coast from Alaska southward to southern California, breeding locally throughout their range.

Tufted Puffins are the largest of the Puffins. In the breeding plumage, they are a sooty brownish or black color; the cheeks are white, and a long tuft of straw colored feathers extends back from each eye; the bill is bright red and greenish yellow. They breed commonly on the Farallones, where two or three broods are raised by a bird in a single season, but much more abundantly on the islands in the north. Their single eggs are laid in burrows in the ground or else in natural crevices formed by the rocks. The eggs are pure white or pale buff and are without gloss. They very often have barely perceptible shell markings of dull purplish color. The eggs are laid about the middle of June. Size 2.80 × 1.90. Data.--Farallone Is., May 27, 1887. Single egg laid in crevice of rocks. Collector, W. O. Emerson.

13. PUFFIN. _Fratercula arctica arctica._

Range.--North Atlantic Coast, breeding from the Bay of Fundy northward. Winters from breeding range along the New England Coast.

The common Puffin has the cheeks, chin and underparts white; upper parts and a band across the throat, blackish. Bill deep and thin, and colored with red, orange and yellow. They breed in large numbers on Bird Rock in the Gulf of St. Lawrence. The nest is either among the natural crevices of the

Page 23

rocks, or in burrows excavated in the ground by the birds. These burrows vary in length from two and a half to four or five feet. Except upon the positive knowledge of the absence of the bird, it is a hazardous thing to put the hand in one of these burrows for the bird can, and will nip the fingers, sometimes to the bone. They lay but a single egg, usually dull white and unmarked, but in some cases obscurely marked with reddish brown. Size 2.50 × 1.75. Data.--So. Labrador, June 23, 1884. Single egg laid at end of burrow in the ground. Collector, J. H. Jameson.

13a. LARGE-BILLED PUFFIN. _Fratercula arctica naumanni._

A more northerly subspecies of the last, inhabiting the Arctic region on the Atlantic side. The bird is somewhat larger but otherwise indistinguishable from the common species. The eggs are exactly the same or average a trifle larger. Size 2.55 × 1.80. Data.--Iceland, July 6, 1900. Single egg in hole under a rock. Collector, Chas. Jefferys.

14. HORNED PUFFIN. _Fratercula corniculata._

Range.--Pacific Coast from Alaska to British Columbia. The Horned Puffin differs from the common in that the blackish band across the throat extends upwards in a point to the bill. Their nesting habits are precisely the same as those of the preceding species. A single pure white egg is laid; the shell is slightly rougher than those of the others. Size 2.65 × 1.80. Data.--Round Is., Alaska, June 24, 1884. Single egg laid at end of burrow in ground; no nest. Collector, G. L. Kennedy.

15. RHINOCEROS AUKLET. _Cerorhinca monocerata._

Range.--Pacific Coast, breeding from British Columbia northward and wintering southward to Lower California.

The Rhinoceros Auklet or Horned Auk has a much smaller bill than the Puffins; in the summer this is adorned at the base by a horn from which it takes its name. There are also slender plumes from above and below the eyes. Unlike the Puffins, these birds sit upon their whole tarsus.

They nest on islands of the North Pacific Coast from Vancouver northward. A single egg is laid in crevices among the rocks or in burrows in the ground. It is similar both in size and shape to that of the Puffins, but is often quite heavily blotched with brown. Size 2.70 × 1.80. Data.--Unak Is., Alaska, June 30, 1900. Egg laid in a fissure of the rocks; no nest. Collector, F. Weston.

Page 24

16. CASSIN AUKLET. _Ptychoramphus aleuticus._

Range.--Pacific Coast from Alaska to Lower California, breeding nearly throughout its range.

A plain appearing bird about 9 in. in length, with blackish upperparts relieved only by a white spot over the eye; breast and throat gray and belly white. This Auklet is fairly abundant on the Farallones, breeding on the lower portions of the island. The late Mr. C. Barlow says that it is found in deserted rabbit burrows and in all probability often excavates its own burrows. It also nests among the cliffs placing its eggs among the rocks in any crevice or tunnel which may offer a dark retreat during the day for they are nocturnal in their habits. The single egg which they lay is dull white in color, the inside of the shell being a pale green, which color can only be seen by holding the egg to the light. They are generally slightly nest stained. Size 1.80 × 1.30. Data.--Coronado Islands, Cal., March 23, 1897. Single egg laid on the bare ground at end of a burrow three and one-half feet long. Collector, E. A. Shives.

Page 25

17. PAROQUET AUKLET.--_Phaleris psittacula._

Range.--The Alaskan Coast, casually farther south in winter.

This bird is about the same size as the preceding, and the plumage is similar, except that it has no white spot over the eye, and the breast is white. It also has a slender plume extending from back of the eye. The bill is very peculiar, being quite deep and rounded and having an upward tendency. It is orange red in color. They breed very commonly on the islands of Bering Strait. Their eggs are laid in the crevices of the cliff, often several feet in and by a crooked path so that it is impossible to reach them. The single chalky white egg is laid in May. Size 2.30 × 1.45. Data.--Rocky Islet in the Aleutians, June 22, 1890. Single egg laid on bare rock in a deep crevice. Collector, Capt. S. Wilson.

18. CRESTED AUKLET. _Aethia cristatella._

Range.--Alaska Coast, similar in form and plumage to the latter, except that the whole under parts are gray and it has a crest of recurved feathers. The nesting season begins in May, the birds nesting upon the same islands and in the same kinds of sites as the last species. The single egg is chalky white. Size 2.10 × 1.50. Data.--Unak Is., Alaska, July 1, 1900. Egg laid in a crevice among the rocks. Collector, F. Weston.

19. WHISKERED AUKLET. _Aethia pygmaea._

Range.--The Alaska Coast.

Much smaller than the preceding; but 7.5 in. in length. Breast gray, belly white; a small tuft of recurved feathers on the forehead and slender white plumes from base of bill over the eye and from under the eye, backwards. The bill in summer is a bright vermillion color. On some of the islands of the Aleutian chain they breed quite abundantly. The nests are placed back in the crevices of the rocks, where the single white eggs are laid. Size 2.00 × 1.25.

Page 26

20. LEAST AUKLET. _Aethia pusilla._

Range.--North Pacific on the islands and coast of Alaska. This is the smallest of the Auklets; length 6.5 in. This species has no crest, but has the slender white plumes extending back from the eye. The entire under parts are white sparsely spotted with dusky. This species is by far the most abundant of the water birds of the extreme Northwest, and thousands of them, accompanied by the two preceding species, nest on the rocky cliffs of the islands of Bering Sea. Their nesting habits are the same as those of the other Auklets, they placing their single white egg on the bare rocks, in crevices on the cliffs. Size 1.55 × 1.10. Data.--Pribilof Is., Alaska, June 8, 1897. Single egg laid in crevice. Thousands breeding on the island.

21. ANCIENT MURRELET. _Synthliboramphus antiquus._

Range.--Pacific Coast, breeding from the border of the United States, northward, and wintering south to southern California.

The Murrelets have no crests or plumes and the bills are more slender than the Auklets and are not highly colored. The ancient Murrelet or Black-throated Murrelet, as it is also called, has a gray back, white under parts and a black head and throat, with a broad white stripe back of the eye and another formed by the white on the breast extending up on the side of the neck. They breed abundantly on the islands in Bering Sea, laying one or two eggs at the end of burrows in the banks or on the ground, and in some localities in crevices on the cliffs. The eggs are a buffy white color and are faintly marked with light brown, some of these being in the shape of spots and others lengthened. Size 2.40 × 1.40. Data.--Sanak Islands, July 1, 1894. Two eggs on the ground under a tuft of grass and in a slight excavation lined with fine grass.

Page 27

23. MARBLED MURRELET. _Brachyramphus marmoratus._

Range.--North Pacific Coast, breeding from Vancouver Island. South in winter to southern California.

In the breeding plumage, this bird is brownish black above, barred with rusty and below is marbled with brownish gray and white. Its nesting habits and eggs are very similar to those of the Ancient Murrelet, they placing their single eggs in holes in the ground or crevices among the cliffs. Size 2.20 × 1.40. Data.--Chichagof Is., Alaska, June 18, 1898. Single egg in crevice on face of cliff. Large colony breeding in company with Ancient Murrelets.

24. KITTLITZ MURRELET. _Brachyramphus brevirostris._

Range.--North Pacific Coast in the Aleutian Islands and north to Unalaska, breeding on isolated islands throughout its range. This species is very similar to the Marbled Murrelet, the chief difference being in the bill which is shorted. They have been found breeding on the same islands with the preceding species. Their single white egg is laid in crevices in the cliffs. Size 2.40 × 1.30. Data.--Sanak Is., Alaska, June 25, 1890. Nest in a hollow under a bunch of rank matted grass. Many ancient Burrelets breeding on the same Islands. Collector, Capt. Tilson.

25. XANTUS MURRELET. _Brachyramphus hypoleucus._

Range.--Resident along the coast of southern and Lower California.

This bird is blackish above and entirely white below, including the sides of the head below the eye. The whole of the under surface of the wing is also white. They breed on the coast islands from Santa Barbara southward. The single egg is laid at the end of a burrow or in crevices among the rocks. It is a pale buffy white in color and thickly, but finely dotted over the whole surface with purplish brown, and with some larger spots at the larger end. Size 2.05 × 1.40. Data.--Galapagos Islands, March 2, 1901. No nest. Single egg laid in a crevice in the rocks. Collector, Rollo H. Beck.

Page 28

26. CRAVERI'S MURRELET. _Brachyramphus craveri._

Range.--Both coasts of Lower California, breeding chiefly on the Gulf side. Craveri Murrelet is very similar to the last except that the under surfaces of the wings are dusky. Breeds on the islands near Cape St. Lucas, burrowing in the ground as do most of the others of this species. They lay a single egg, the ground color of which is buff; they are quite heavily blotched with brownish. Size 2.00 × 1.40.

27. BLACK GUILLEMOT. _Cepphus grylle._

Range.--Coasts and islands of the North Atlantic, breeding from Maine northward to southern Greenland. Guillemots are larger birds than the Murrelets (length 13 inches) and their plumage is entirely different. This species in summer is entirely black except the wing coverts which are white. The bases of the greater coverts, however, are black, this generally breaking the white mirror as it is called. The under surfaces of the wings are white. Legs red. These birds breed abundantly on the rocky islands and high cliffs along the coast. Soon after the first of June the eggs are laid in the crevices of the rocks and sometimes upon the bare ledges. Two or three eggs make the set. The ground color is a pale bluish or greenish white and the markings are various shades of brown and black. Size 2.40 × 1.60. Data.--Grand Manan, June 15, 1896. Two eggs laid in a cavity back of large boulder. No nest. Collector, D. H. Eaton.

Page 29

28. MANDT'S GUILLEMOT. _Cepphus mandti._

Range.--North Atlantic coast, more northerly than the preceding, breeding from Labrador to northern Greenland.

The bird differs from the Black Guillemot only in having the bases of the coverts white also. The nesting habits and eggs are identical. They nest in colonies of thousands and place the eggs upon the bare rock with no attempt at nest building. Generally the eggs are in the crevices so as to be difficult to get at. Size 2.30 × 1.55. Data.--Depot Island, Hudson Bay, June 6, 1894. Two eggs laid on bare rocky ground. Collector John Comer.

29. PIGEON GUILLEMOT. _Cepphus columba._

Range.--The Pacific Coast of North America, breeding from southern California northward. This bird is very similar to the Black Guillemot except that the under surfaces of the wings are dark. They breed abundantly on some of the islands of Bering Sea and a few of them nest on the Farallones. They lay their two eggs on the bare rock in dark crevices. The color is grayish or pale greenish blue and the markings are brown and black with paler shell markings of lilac. Size 2.40 × 1.60. Data.--S. Farallone Islands, Cal. Two eggs laid on gravel at the end of a burrow, about two feet from the entrance and 285 feet above the sea level. Collector, Claude Fyfe.

30. MURRE. _Uria troile troille._

Range.--North Atlantic coasts and islands, breeding from Bird Rock northward. Murres are similar in form to the Guillemots, but are larger, being about 16 inches in length. Entire head and neck sooty brown; rest of upper parts grayish black except the tips of the secondaries which are white. Under parts white. These birds nest by thousands on Bird Rock and on the cliffs of Labrador. They build no nests but simply lay their single egg on the narrow ledges of cliffs, where the only guarantee against its rolling off is its peculiar shape which causes it, when moved, to revolve about its smaller end instead of rolling off the ledge. The eggs are laid as closely as possible on the ledges where the incubating birds sit upright, in long rows like an army on guard. As long as each bird succeeds in finding an egg to cover, on its return home, it is doubtful if they either know or care whether it is their own or not. The ground color of the eggs vary from white to a deep greenish blue and the markings of blackish brown vary in endless patterns, some eggs being almost wholly unspotted. Size 3.40 × 2.00. Data.--South Labrador, June 19, 1884. Single egg laid on the bare cliff. Large colony breeding. Collector, M. A. Grasar.

30a. CALIFORNIA MURRE. _Uria troille californica._

Range.--Pacific Coast, breeding from the Farallones north to Alaska.

This Pacific form of the common Murre is the most abundant breeding bird on the Farallones. Their eggs are used in enormous numbers for commercial purposes and these islands being located, as they are, within easy distance from San Francisco, thousands of dozens of the eggs are sold yearly, chiefly to bakeries. Although continually robbed, their numbers have not as yet diminished to any great extent. They lay but a single egg on the bare ledge. Individual eggs are indistinguishable from the last species but in a large series the ground color averages brighter. They show the same great difference in color and markings. The first set is laid in May, but owing to their being so often molested, fresh eggs can be found during August. Data.--Farallones, July 4, 1895. Single egg laid on bare cliff. Collector, Thos. E. Slevin.

31. BRUNNICH MURRE. _Uria lomvia lomvia._

Range.--North Atlantic Coast, breeding range the same as the common Murre.

This species differs from the common Murre in having a shorter and thicker bill, the base of the cutting edge of which is less feathered. They breed on the same islands in company with the common Murre and their eggs are indistinguishable. Data.--Coast of South Labrador. Single egg laid on ledge of cliff. About three hundred birds in the colony.

Page 31

31a. PALLAS MURRE. _Uria lomvia arra._

Range.--The Pacific coasts and islands.

This is the Pacific form of Brunnich Murre. Its breeding range is more northerly than that of the California variety. Countless thousands of them breed on the islands off the coast of Alaska, their breeding habits and eggs being the same as the more southern form.

32. RAZOR-BILLED AUK. _Alca torda._

Range.--North Atlantic coast, breeding from Bird Rock northward and wintering south to the Middle States on the coast.

The Razor-billed Auk is in form similar to the Murres, but the bill is very different, being deep and thin, and with the upper mandible rounded at the tip. Entire upper parts black shading to brownish on the throat. Under parts and tips of secondaries, white; line from eye to bill and another across the middle of the bill, white. They nest in large numbers on Bird Rock in company with the Murres and in still greater numbers off the coast of Labrador. Their eggs are not placed in as exposed positions as the Murres, being generally behind boulders or in crevices. This is necessary because, not being of the pear-shaped form of the Murres, they would be very apt to be dislodged if commonly placed on the narrow ledges. The eggs vary endlessly in marking but do not show the differences in ground color that the Murres do. The color is white, grayish or buffy. But one egg is generally laid, although two are sometimes found. Size 3.00 × 2.00. Data.--Bay of Fundy. June 17, 1891. Single egg laid on bare rock in a crevice under loose rocks. Collector, A. C. Bent.

Page 32

33. GREAT AUK. _Plautus impennis._

Range.--Formerly the whole of the North Atlantic coasts. Now extinct.

These great auks formerly dwelt in large numbers on the islands of the North Atlantic, but owing to their lack of the powers of flight and the destructiveness of mankind, the living bird has disappeared from the face of the earth. Although they were about thirty inches in length, their wings were even smaller than those of the Razor-billed Auk, a bird only eighteen inches in length. Although breeding off the coast of Newfoundland, they appeared winters as far south as Virginia, performing their migration by swimming alone. The last bird appears to have been taken in 1844, and Funk Island, off the coast of Newfoundland, marks the place of their disappearance from our shores. There are about seventy known specimens of the bird preserved, and about the same number of eggs. The immediate cause of the extinction of these birds was their destruction for food by fishermen and immigrants, and later for the use of their feathers commercially. The single egg that they laid was about 5.00 x 3.00 inches, the ground color was buffy white, and the spots brownish and blackish. The markings varied in endless pattern as do those of the smaller Auk. There are but two real eggs (plaster casts in imitation of the Auks eggs are to be found in many collections) in collections in this country, one in the Academy of Natural Science, Philadelphia, and the other in the National Museum, at Washington. Through the kindness of Mr. Witmer Stone, of the Academy of Natural Science, we are enabled to show a full-sized reproduction from a photograph of the egg in their collection.

34. DOVEKIE. _Alle alle_.

Range.--Coasts and islands of the North Atlantic and East Arctic oceans, breeding in the Arctic regions and wintering as far south as the Middle States. The little Dovekie or Sea Dove is the smallest member of the family, being only 8 inches in length, and is the only member of the sub-family allinæ. The form is very robust and the bill is short and stout. In summer the plumage is black above; the throat and upper breast are sooty brown, and the under parts are white, as are also the tips of the secondaries and edges of the scapulars. They nest in large numbers on the Rocky cliffs of islands in the East Arctic. Their single pale greenish blue egg is placed in a crevice of the rocks. Size 1.80 × 1.25. Data.--Greenland, June 8, 1893. Single egg laid in a crevice of a sea cliff.

LONG-WINGED SWIMMERS. Order II. LONGIPENNES SKUA AND JAEGERS. Family STERCORARIIDAE

Skuas and Jægers are birds having a Gull or Tern-like form and with a hooked bill, the base of which is covered with a scaly shield. They have webbed feet and are able to swim and dive, but they commonly get their living by preying upon the Gulls and Terns, overtaking them by their superior speed and by their strength and ferocity forcing them to relinquish their food. The Jægers especially are one of the swiftest and most graceful birds that fly.

Page 36

35. SKUA. _Megalestris skua_.

Range.--Coasts and islands of the North Atlantic, chiefly on the European side; rare on the Atlantic coast of North America.

Skuas are large (22 inches in length) and very powerfully built birds, having the general form of a Gull. Their whole plumage is a dingy brownish black color, palest below. Breeds in Iceland and possibly on some of the islands in Hudson Strait. The nest is a hollow on the ground in the marsh grass and is lined with grass. The two eggs which they lay have an olive greenish ground, spotted with dark brown. Size 2.75 × 1.90.

36. POMARINE JAEGER. _Stercorarius pomarinus._

Range.--Northern Hemisphere, breeding within the Arctic Circle, more commonly in the Old World.

In the breeding plumage, this Jæger has the crown and face blackish; back and sides of head, throat and under parts pure white, except the pointed stiffened feathers of the neck which are yellow. Back, wings and tail blackish, the latter with the two middle feathers lengthened about four inches beyond the rest of the tail, and broad to the tips, which are twisted so that the feathers are vertical. They breed throughout the Arctic regions, but not as commonly in America as the following species. The nest is on the ground in the marsh grass and is made of grass and moss. They lay two and rarely three eggs of an olive brown or greenish color. These are spotted with brown and black. Size 2.20 × 1.70.

Page 37

37. PARASITIC JAEGER. _Stercorarius parasiticus._

Range.--Northern Hemisphere, wintering south to South America.

The Parasitic Jæger is very similar to the Pomarine except that the central tail feathers are pointed and are straight instead of twisted. It is an abundant bird in Alaska, breeding from the Aleutian Chain northward.

They locate their nests in the highest parts of marshy places, the nest itself being only a depression in the ground lined with grass and moss. The two eggs have an olive greenish or brownish ground and are marked with various shades of brown and black. Size 2.15 × 1.65.

38. LONG-TAILED JAEGER. _Stercorarius longicaudus._

Range.--Arctic America; south in winter to South America.

The long-tailed Jæger is, according to length, the largest of the Jægers, being 21 in. long; this is, however, due to the long sharp pointed central pair of tail feathers, which extend about eight inches beyond the others, and from the most noticeable distinguishing point from the former species. The plumages that have been described are the light phases; all the Jægers have a dark phase in which the plumage is a nearly uniform sooty brown, lightest below.

The Long-tailed Jægers are the most numerous in Alaska and are even more graceful in flight than are the Gulls and Terns, floating, skimming, sailing, plunging, and darting about with incredible swiftness and ease. Like the others of this family, they pilfer their food from the Gulls, and are also very destructive to young birds and eggs. Their eggs are either laid on the bare ground or in a slight depression, scantily lined with grasses. The eggs are indistinguishable from those of the preceding species except that they average a trifle smaller. Size 2.10 × 1.50.

Page 38

GULLS and TERNS. Family LARIDÆ

Gulls are webbed footed birds having a slight hook to the end of the upper mandible. Their plumage is generally a silvery gray above and white below. They nest in large colonies, some on the islands of fresh water inland, but mostly on the sea coast. They procure their food from the surface of the water, it consisting mostly of dead fish and refuse matter, and crustacea which they gather from the waters edge. When tired they rest upon the surface of the water, where they ride the largest waves in perfect safety.

Terns are birds of similar plumage to the Gulls, but their forms are less robust and the bills are generally longer and sharply pointed. Their food consists chiefly of small fish which they secure by hovering above the water, and then plunging upon them. They are less often seen on the surface of the water than are the Gulls.

Page 39

39. IVORY GULL. _Pagophila alba._

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

The little Snow Gull, as it is often called, is eighteen inches in length. In the breeding season the plumage is entirely white; the bill is tipped with yellow and there is a red ring around the eye. These Gulls nest in large colonies in the Arctic Regions, placing their nests on the high rocky cliffs. The nest is made of grass, moss and rubbish, and the three eggs are laid during June. The eggs are olive color and the markings are dark brown.

40. KITTIWAKE. _Rissa tridactyla trydactyla._

Range.--North Atlantic and Arctic regions, breeding from the Gulf of the St. Lawrence northward and wintering south to the Great Lakes and Long Island.

The Kittiwake is sixteen inches in length, has a pearly gray mantle, black tips to the primaries, and remainder of plumage white. Its hind toe is very small being apparently wanting in the eastern form, while in the Pacific it is more developed. These are very noisy Gulls, their notes resembling a repetition of their name. They are very common in the far north, placing nests on the ledges of high rocky cliffs, often in company with Murres and Auks. They gather together a pile of sticks, grass and moss, making the interior cup-shaped so as to hold their two or three eggs. Large numbers of them breed on Bird Rock, they occupying certain ledges while the Gannets and Murres, which also breed there, also have distinct ledges on which to make their homes. The breeding season is at its height during June. The eggs are buffy or brownish gray and are spotted with different shades of brown. Size 2.25 × 1.60. Data.--So. Labrador, June 15, 1884. Three eggs. Nest made of seaweed and moss, placed on ledge of cliff. Many Murres nesting on other ledges.

Page 40

40a. PACIFIC KITTIWAKE. _Rissa tridactyla pollicaris._

Range.--Coast of the North Pacific, wintering south to California.

The Pacific Kittiwake breeds in immense rookeries on some of the islands in Bering Sea. They are well distributed over Copper Island where they nest in June and July, choosing the high ledges which overhang the sea. The nesting habits and eggs are precisely the same as those of the common Kittiwake.

41. RED-LEGGED KITTIWAKE. _Rissa brevirostris._

Range.--Northwestern coasts, breeding in high latitudes.

This Kittiwake is similar to the preceding, with the exception that the legs are bright red, the mantle is darker, and the bill is shorter. This species was found by Dr. Leonard Stejneger to be a very abundant nesting bird on islands in Bering Sea, selecting steep and inaccessible rocks and ledges on which to build its nest. Their nesting habits are precisely the same as the Pacific Kittiwake, but they most often nest in separate colonies, but can be distinguished readily when nesting together by the darker mantles when on the nest and the red legs when flying. Grass, moss and mud are used in the nest. The ground color of the eggs is buffy or brownish, and the spots are dark brown and lilac. Size 2.15 × 1.50.

42. GLAUCOUS GULL. _Larus hyperboreus._

Range.--Arctic regions, south in winter to Long Island, the Great Lakes, and San Francisco Bay.

This Gull shares with the Great Black-backed Gull the honor of being the largest of the Gulls, being 28 inches in length. Mantle light gray; it is distinguished by its size and the primaries, which are white to the tips. A powerful bird that preys upon the smaller Gulls and also devours the young and eggs of smaller birds.

They nest on the ground on the islands and shores of Hudson Bay, Greenland, etc. The nest is made of seaweed, grass and moss and is generally quite bulky. The two or three eggs are laid in June. They are of various shades of color from a light drab to a brownish, and are spotted with brownish and black. Size about 3.00 × 2.20.

Page 41

42.1. POINT BARROW GULL. _Larus barrovianus._

Range.--Northwest coast from Bering Sea to Point Barrow.

This species is almost identical with the Glaucus Gull, averaging perhaps a trifle smaller. Its standing as a distinct species is still questioned and has not yet been decided satisfactorily. Early in June their nests are built on remote islands in Bering Sea. These nests are the same as the last species, large piles of vegetation, hollowed on top for the reception of the eggs. The eggs have the same variations in color and markings as the Glaucus Gull. Size 3.00 × 2.10. Data.--Herschel Is., Alaska, July 1, 1900. Nest made of seaweed and grass; placed on the ground. Three eggs. Collector, Rev. I. O. Stringer.

43. ICELAND GULL. _Larus leucopterus._

Range.--Arctic regions, south in winter to the Middle States.

This Gull in appearance is precisely like the two preceding ones but is considerably smaller; 24 inches in length. A very common bird in the north, breeding in colonies of thousands on many of the islands. It is regarded as one of the most common of the larger Gulls in Bering Sea and also nests commonly in Hudson Bay and Greenland, as well as in the Eastern Hemisphere. They nest indifferently on high rocky cliffs or on low sandy islands. Except when the eggs are laid in a sandy depression in the soil, quite bulky nests are made of seaweed and moss. The eggs are laid about the first of June; they number two to three and have a ground color of brownish or greenish brown and are blotched with umber. Size 2.80 × 1.83. Data.--Mackenzie Bay, Arctic America. June 18, 1899. Nest made of seaweed and grass on an island in the bay.

Page 42

44. GLAUCOUS-WINGED GULL. _Larus glaucescens_.

Range.--North Pacific coast, breeding from British Columbia northwards and wintering from the same country to southern California.

This Gull is very like the preceding except that the primaries are the same color as the mantle, and are tipped with white. Length about 27 inches. Not so northerly distributed a bird as the previous ones, and consequently better known. They breed in large numbers both on the high rocky cliffs of the islands along the coast and on the low sandy islands of the Aleutian Chain. On Copper Island they breed on the inaccessible cliffs overhanging the water. As in the case of the Iceland Gull, when the nests are on the cliffs, a large nest of seaweed is made, whereas if they are on the ground, especially in sandy places no attempt is made at nest-building. The eggs have a greenish brown ground color and dark brown spots. Size 2.75 × 2.05. Data.--West Coast of Vancouver Island. June 20, 1896. Three eggs; nest made of seaweed. Located on a low ledge. Collector, Dr. Newcombe.

45. KUMLIEN'S GULL. _Larus Kumlieni_.

Range.--North Atlantic coast, breeding in Cumberland Sound and wintering as far south as Long Island.

This bird differs from the Glaucous-winged only in the pattern of the gray markings of the primaries and in having a little lighter mantle. It is quite common in its breeding haunts where it places its nest high up on the ledges of the cliffs. The eggs are not different apparently from glaucescens.

46. NELSON'S GULL. _Larus nelsoni_.

Range.--Coast of Alaska.

Plumage exactly like that of Kumlien Gull and questionably a new species. The nests and eggs are not to be distinguished from the preceding.

Page 43

47. GREAT BLACK-BACKED GULL. _Larus marinus_.

Range.--North Atlantic on both the American and European sides; breeds from Nova Scotia northward and winters south to the Great Lakes and the Middle States.

The largest of the Gulls (thirty inches long) and unlike any other. The mantle is dark slaty black, and the primaries are black with white tips. The bill is very large and powerful and quite strongly hooked. They are quite abundant birds in their range, and are very quarrelsome, both among themselves and other species. They do not breed in as large colonies as do the other Gulls, half a dozen pairs appropriating a small island to the exclusion of all other birds. They are very rapacious birds and live to a great extent, especially during the breeding season, upon the eggs and young of other birds such as Ducks, Murres and smaller Gulls. They place their nests upon the higher portions of sandy islands. They are made of grasses and seaweed. The three eggs are laid early in June; they are grayish or brownish, spotted with brown and lilac. Size 3.00 × 2.15. Data.--South Labrador, June 21, 1884. Three eggs. Nest on a small island off the coast; of grasses and moss.

48. SLATY-BACKED GULL.--_Larus schistisagus_.

Range.--North Pacific and Arctic Oceans.

This Gull, which is similar to the Great Black-backed, but is smaller and has a lighter mantle, does not breed in any considerable numbers on the American side of the Pacific. It nests in June on some of the islands in Bering Sea and probably more commonly farther north. They often nest in company with other species, placing their small mounds of seaweed on the ground on the higher parts of the islands. The full set contains three eggs of grayish or brownish color, spotted with dark brown or black. Size 2.90 × 2.00. Data.--Harrowby Bay, N. W. T. Canada, June 11, 1901. Nest of grass, roots and mud and lined with dry grass; on point making into the bay. Collector, Capt. H. H. Bodfish.

Page 44

49. WESTERN GULL. _Larus occidentalis._

Range.--Pacific Coast, breeding from southern California to British Columbia.

This bird, which is the most southerly distributed of the larger Gulls is twenty-four inches in length. Mantle slate colored; primaries black, both these and the secondaries being broadly tipped with white. These Gulls nest abundantly on the Farallones, the majority of them showing a preference for the lower portions of the island, although they nest on the ledges also. Besides man, these Gulls are the greatest enemies that the Murres have to content against. They are always on the watch and if a Murre leaves its nest, one of the Gulls is nearly always ready to pounce upon the egg and carry it away bodily in his bill. The Gulls too suffer when the eggers come, for their eggs are gathered up with the Murres for the markets. They make their nests of weeds and grass, and during May and June lay three eggs showing the usual variations of color common to the Gulls eggs. Size 2.75 × 1.90.

50. SIBERIAN GULL. _Larus affinis._

This bird does not nest in North America, and has a place on our list, by its accidental occurrence in Greenland. It is an Old World species and its nesting habits and eggs are like those of the Herring Gull.

51. HERRING GULL. _Larus argentatus._

Range.--Whole of the Northern Hemisphere, breeding from Maine and British Columbia northward and wintering south to the Gulf.
