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.
