This small, bird-killing Hawk dashes recklessly after its victims,
following them through thick cover. It is less often seen in the open
than the Sparrow Hawk, which it resembles in size, but from which it may
be known by its different color, longer tail, and much shorter wings. It
nests in trees 15-40 feet from the ground. The eggs, 3-6 in number, are
bluish white or cream, marked with brown and are laid in May.

This is the real 'Chicken Hawk,' but it is less often seen and heard
than the soaring, screaming Buteos to which the name is usually applied.
It resembles the Sharp-shinned in habits but being larger may prey on
larger birds. The female may be easily distinguished from the
Sharp-shinned by her larger size, but the male is not appreciably larger
than a female Sharp-shin.

The nest is built in a tree 25-50 feet up. The bluish white, rarely
spotted eggs are laid in late April or early May.
