Grey Butcherbirds are aggressive predators. They prey on small animals, including birds, lizards and insects, as well as some fruits and seeds. Uneaten food may be stored in the fork or a branch or impaled. Grey Butcherbirds sit on an open perch searching for prey which, once sighted, they pounce on. Most mobile prey is caught on the ground, though small birds and insects may be caught in flight. Feeding normally takes place alone, in pairs or in small family groups.
