features
The 50 cm long thick-billed strangler crow is a predominantly black bird with a white crescent moon on its wings and a white base and tip of its tail. The iris is yellow. Her call is a loud “karrawong”.
Occurrence
The thick-billed shrike crow lives in sparse forests, bush, fields and the outskirts of eastern Australia. In the north of the distribution area it is a resident bird; in the south it migrates back and forth between higher and lower regions.
behavior
Outside of the breeding season, the thick-billed shrike crow lives in large flocks. They are then occasionally associated with yellow-naped bowerbirds and silk arborebirds.
The diet of the thick-billed strangler crow includes carrion, small vertebrates, bird eggs, insects and berries. The bird impales prey on thorns or stores it in crevices and forks of branches.
Reproduction
Between July and January, the female incubates three eggs in a bowl-shaped nest in a fork of a branch for about three weeks. The young birds fledge at three weeks.
