The black-headed monitor (Varanus tristis) is a relatively small species of monitor lizards native to Australia. It is placed in the subgenus Odatria. These arboreal monitors are usually found in grassy woodlands, where they inhabit dead hollow limbs in trees and shelters under the bark of standing trees. The black-headed monitor prefers narrow spaces in which to shelter. Varanus tristis preys mainly on insects, but also consumes small lizards, eggs, and rodents.
