Northwestern Crow

Quoted from Bird Web
Behavior

Outside the breeding season, Northwestern Crows are quite sociable, roosting and foraging in large flocks. They are intelligent and opportunistic, and quickly take advantage of new sources of food. They generally feed on the ground or in shallow water. They drop hard-shelled items onto hard surfaces, such as rocks and roads, to break them open. Northwestern Crows foraging in intertidal areas often store extra food during low tide, when it is plentiful, and consume it during the following high tide, when the intertidal zone is under water..

Diet

Northwestern Crows are omnivores. Because they live in coastal areas, much of their diet is aquatic creatures, shellfish, fish, seabird eggs, and various aquatic invertebrates. They also eat carrion and garbage.

Nesting

Northwestern Crows are monogamous and form long-term pair bonds. Sometimes one of the offspring from a previous year stays with the pair to help feed the nestlings. Both members of the pair help build the nest, which is a bulky, stick platform, lined with mud, moss, grass, rootlets, and cedar bark. The nest is usually in the canopy of a tree, but can also be in a shrub or on the ground. The female incubates 3-6 eggs (usually four) for 17-20 days. The female broods the young constantly for about four days, and then helps the male and helper bring food. The young start venturing out of the nest onto nearby branches at 26-33 days, and then begin to fledge about three days later (typically at 29-35 days). The young stay on the parents' territory for another couple of weeks, and are fed by the parents for a few weeks after leaving the territory. Read more!
