t, but
averaging, perhaps, fifteen feet. The eggs are bluish white, beautifully
blotched and spotted with shades of brown.

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.

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 th
