In northern Pennsylvania, they are often seen along Interstate 80, where they feed on road-killed deer, raccoons, opossums, etc. Ravens also prey upon sick and injured animals. A raven is every bit as alert as a crow and possesses sharp eyesight and hearing. After mating, a pair will seek out an isolated nesting spot, usually at least a mile away from any other ravens. Nests are built on cliffs or near the tops of large trees.
Ravens often build a new nest on top of last year's nest.
Nests are constructed of large sticks, twigs and grapevines. The central hollow is lined with deer hair, moss, shredded bark and grass. Incubation, which is mainly by the female, lasts about three weeks. Young are altricial. They leave the nest about one month after hatching.
