Notes

The largest of our soaring hawks, the Red-tailed
Hawk is often seen sailing smoothly overhead, wheeling and turning in
the rising currents of air with scarcely a flap of the wings. These
powerful predators feed mainly on rats, mice, rabbits and other small
mammals, as well as snakes, insects, and a few birds. They prefer to
hunt over open country, perching or soaring overhead until prey is
spotted below. Because of their long, broad wings, Red-tails are not
particularly agile, and do not hunt well in dense wooded areas, but they
are able to swoop down and seize their prey with massive and powerful
talons.
These
birds usually nest high in the tree canopy, as much as 120 feet above
the ground. The nest is built by both sexes, and is usually bulky
enough to provide adequate support for the young. Incubation of the
eggs requires 28 to 35 days. During the young nestling phase, the
female tears the food into small pieces to feed the nestlings, and
broods them until they are roughly 4 weeks old. Subsequently food is
dropped into the nest, and the young must feed themselves. Branchers
leave the nest 6 to 7 weeks after hatching, but are unable to fly well
for several more weeks. It was a juvenile in this stage of development
that is described in Case 1. At this stage, the adult birds had no
difficulty supplying the juvenile that remained in the original nest as
well as the juvenile that was on the nest platform nearby. The
fledglings remain dependent on the adults for 5 to 10 weeks after
fledging, as they gradually develop their hunting skills.
