About These Birds
Blue Jay
The blue jay is a bold, intelligent member of the corvid family known for its striking plumage and loud calls. Blue jays are important dispersers of oak trees, as they cache thousands of acorns each autumn. Their complex social behavior includes mimicking the calls of hawks to scare other birds from feeders.
Bismarck Crow
The Bismarck Crow is a glossy black crow endemic to the Bismarck Archipelago and adjacent islands in Papua New Guinea. Like other crows, it is highly intelligent and omnivorous, feeding on carrion, fruits, invertebrates, and small vertebrates. It inhabits forest, forest edges, and coastal areas.
