They often nod their heads in display and appear to only come to the ground to cross to another tree or high point.They remain shy and wary always keeping a tree trunk or branch between themselves and danger. They can open their mouths wide, revealing an orange colour inside. They are not poisonous. They sleep at night in a hollow branch or unpeeling bark. Breeding males have more massive heads than females, and also develop swollen, scarred tail bases from fighting. The female lays 5-14 oval, soft-shelled eggs (10-21 x 22-28 rnm) in a hole dug in moist soil.
