Squirrels, snowshoe hares, grouse, corvids, woodpeckers, and other medium to large songbirds are all potential prey of the goshawk. |
The passerines of Australia, also known as songbirds or perching birds, include wrens, the magpie group, thornbills, corvids, pardalotes, lyrebirds. |
The corvids of North America consist of one species of jackdaw, four crows, two ravens, one nutcracker, two magpies, and ten species of jays. |
Crows belong to the family of corvids, which also includes rooks, jays, ravens and jackdaws. |
The lack of suitable nest sites has also resulted in increased predation by corvids and mammals on the eggs and chicks. |
I responded to Dave that mobbing behavior, when smaller birds team up to harry a larger one, is common in many bird species, from corvids to raptors to songbirds. |
