Fun Fact(s):
Chicks tend to be very precocial & inquisitive.
Though bittern in name, they’re not closely related to bitterns (which are herons). Closest relative is Kagu of New Caledonia.
Sometimes kept by humans in native range as biological pest control.
If predator approaches nest, a parent will do broken-wing display to distract it.
Named for sun-like orange-chestnut part on primary wing feathers/across tail. Birds display/spread wings as threat/defense display, typically accompanied by bowing/low hissing. Spots on wings can be mistaken for eyes.
Very shy in wild but somewhat tame in captivity.
