Diet

Its diet includes small mammals, frogs , snakes , lizards, large insects, and occasionally birds. It feeds over or near marshes, swamps , wooded lakes , or ponds . Commonly it will watch from a perch and fly down to capture its prey .

Reproduction

The breeding season begins in late January, peaks in early March to early April, and extends into June. Breeding habitat is usually associated with water, in swamps or bottomlands The nests are built by both the male and female, 20-60 feet above the ground in crotches of large trees . The nests are built of large sticks , twigs , leaves, moss, lichen, and conifer needles . The female lays 2-4 (usually 3) eggs that are whitish and marked with brown. The male and female both take turns incubating for approximately 28 days, at which time the young hatch . The young are semi-altricial, immobile, downy , and born with their eyes open. The young leave the nest in 39-40 days, but remain close to the adults after fledging for additional care.
