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.
Laughing Kookaburra
The laughing kookaburra is the largest kingfisher in the world, famous for its raucous laughing call that has become an iconic sound of the Australian bush. Despite being a kingfisher, it rarely eats fish, preferring terrestrial prey. Family groups perform chorus calls at dawn and dusk to mark their territory.
