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.
Superb Fairywren
The superb fairywren is one of Australia's most beloved and recognizable birds, with breeding males dressed in spectacular violet-blue plumage. These tiny birds live in cooperative family groups where helpers assist the breeding pair in raising young. Males pluck and present yellow flower petals to females as part of courtship.
