Part 14
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.

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.

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.

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.

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.

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.
