The Jackie Hangman gets it’s name from the habit of impaling prey on thorns to store for later consumption. One of the reasons of this species success lies in its varied diet and clever hunting techniques. It often uses a sit and wait technique in which it hunts from a prominent perch, remaining almost motionless, scanning the area with its sharp eyes. When it spots something it glides to the ground and attempts to catch its prey. It has a varied diet of insects, frogs, reptiles and birds.
It gives a jumbled mix of shrike-like swizzling sounds including some imitations and a harsh Dzzzttt-dzzzt-dzzzt alarm call.
