ather retiring, unwary Hawk which nests in thick woods and is less
often seen in the open than the Red-shoulder, but, when migrating,
hundreds pass high in the air, with other Hawks. Its call is a high,
thin, penetrating whistle. It nests in late April and early May, laying
2-4 whitish eggs marked with brown.

ROUGH-LEGGED HAWK

_Archibuteo lagopus sancti-johannis_

Legs feathered to the toes; basal half of tail
white; belly black. Some individuals are wholly
black. L., male, 21; female, 23.

_Range._ Breeds in northern Canada; usually rare
and irregular in the northern U.S., from November
to April.

Washington, rare and irregular W.V. Ossining,
casual. Cambridge, T.V., not common, Nov.-Dec.;
Mch.-Apl. N. Ohio, not common W.V., Nov. 20-Apl.
3. Glen Ellyn, quite common W.V., Oct. 12-Apl. 30.

Frequents fields and marshes, where it hunts to and fro after mice,
which form its principal fare.

GOLDEN EAGLE

_Aquila chrysaetos_

With the Bald Eagle, largest of our raptorial
birds; with a general resemblance to the young of
that species, in which the head and tail are dark,
but with the legs feathered to the toes. L., male,
32-1/2; female, 37-1/2.

_Range._ Northern parts of the northern
Hemisphere; in the United States, rare east of the
Mississippi.

Washington, rare W.V., Ossining, A.V. Cambridge, 1
record. N. Ohio, rare W.V. SE. Minn., P.R.

The Golden Eagle is so rare in the eastern United States and its general
resemblance to a young Bald Eagle is so close, that only an experienced
ornithologist could convince me that he had seen a Golden Eagle east of
the Mississippi.

BALD EAGLE

_Haliaeetus leucocephalus leucocephalus. Case 3, Fig. 11_

When immature the head and tail resemble the body
in color, and at this age the bird is sometimes
confused with the more western Golden Eagle. The
latter has the head browner and the legs feathered
to the toes. L., male, 33; female, 35-1/2.

_Range._ North America but rare in the interior
and in California, migratory at the northern limit
of its range.
