The Black-backed Butcherbird (Cracticus mentalis) replaces the Grey Butcherbird on the Cape York Peninsula and in southeastern New Guinea. Like the Gray, it lives in territorial pairs and hunts through the mid-strata of open eucalypt forest and woodland. Though diving onto terrestrial prey from vantage perches, it also spends much time poking into cracks and crannies along branches and among the shrubbery.
Black-backed Butcherbird diet is large insects, arboreal lizards, small birds, and nestlings are its main prey, but Acacia seeds are also picked up. To advertise territory, particularly during breeding, the partners sing antiphonally, each contributing part of the complete song in turn.
