The same climate change-driven threats that put birds at risk will affect other wildlife and people, too. When hawks and falcons stream across the sky in large numbers, you need a distinct set of birding skills to tell them apart.
Audubon Mid-Atlantic brings together a panel of Brewers for the Delaware River members and city leaders to discuss the importance of watershed health for birds, people, and beer.

An inhabitant of open country, it is commonly seen perched on roadside poles or sailing over fields and woods. Although adults usually can be recognized by the trademark reddish-brown tail, the rest of their plumage can be quite variable, especially west of the Mississippi: Western Red-tails can range from blackish to rufous-brown to nearly white.
Photo gallery. Feeding Behavior Does most hunting by watching from a high perch, then swooping down to capture prey in its talons. Eggs , sometimes 4, rarely A large hawk, usually weighing between two and four pounds, this species shows a great deal of individual variation in plumage.
The adult has a rufous-colored tail that may or may not have a black terminal bar. Adults are dark brown on the back and the top of their wings. The underside of the bird is usually light with a dark belly band, and a cinnamon wash on the neck and chest.
However, there are both light-colored and dark-colored races that confound this. Melanistic dark birds have very little light coloring and appear totally dark brown. In all of the color phases, the underside of the feathers is light-colored. Immatures resemble the adults, except that their tails are brown with dark bars; the red tail molts in during its second year.
Interesting to note, most hawks captured for falconry in the United States are Red-tails. The female is up to a third larger than the male. Typically, the adult bird is a dark brown above, white breast, and a band across the belly.
Immature Red-tails are similar in appearance, except the tail is brown and banded instead of reddish. The mating and breeding habits of these birds begins at about three years of age and includes airial displays meant to advertise their readiness for breeding.
These courtship displays show their agility as they soar high in the sky making wide circles and then diving to treetop levels. Generally monogamous birds, remaining with the same mate throughout the breeding season and often pairing for life and staying in the same nesting territory every year, even using the same nest.
The male and female participate in the building of the nest which is a platform constructed of sticks and twigs, lined with bark and greenery. Despite that, the "couples" do not usually share tree living environments. Male and female red-tailed hawks share the responsibility of putting together suitable nests. They often simply spruce up pre-existing nests they made before, although they do also frequently construct entirely new ones.
These hawks require roughly 4 to 7 days to make their nests. Red-tailed hawks generally establish their nests in locations close to fields, lakes or sides of creeks. They also prefer airy environments for building nests. Their nests are situated either in high trees or on cliffs. Occasionally, when other options are scarce, they even set their nests up in windows of buildings.
