The adults of this species are very light colored; bluish gray above and white beneath. Young birds of the first two years are brown, much lighter on the under parts. In both the old and young they have a large white patch at the base of the tail. Nest is made in and on swampy ground; four to seven eggs; white (1.80 × 1.40).
SHARP-SHINNED HAWK.
332. Accipiter velox. 12 inches.
This little hawk is one of the most active of the family, and from this fact it gets its name (Velox), meaning swift. It is often seen in woods, orchards or even in large cities, in which latter place it does good service in catching English sparrows. They also eat a great many mice and meadow moles. It is one of the most daring as well as beautiful of the small hawks.
Nest.—It is a rude and very frail platform of twigs and leaves placed in the crotch of a tree, usually at about fifteen feet from the ground, sometimes higher. Three white eggs, blotched with brown.
COOPER HAWK.
333. Accipiter cooperi. 16 inches.
The markings of this bird are the same as the preceding and its larger size is the only difference. Also like the last this is a very destructive species to the small birds and chickens. Their nests are placed in taller trees at higher elevation from the ground than the former, and built in the same manner. Three bluish white eggs unmarked or faintly specked with brown (1.90 × 1.45).
