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.
Australian Raven
The Australian Raven is the largest corvid in Australia, found in open woodland, farmland, and coastal areas across southern and eastern Australia. Weighing about 660g with a wingspan of 71.2cm, it is entirely black with a shaggy throat hackle. It feeds opportunistically on carrion, invertebrates, small vertebrates, and human refuse.
