Night heron

Description:

Adults are short-necked, short-legged and stout herons with a primarily brown or grey plumage, and, in most, a black crown. Young birds are brown, flecked with white. At least some of the extinct Mascarenes taxa appear to have retained this juvenile plumage in adult birds. Night herons nest alone or in colonies on platforms of sticks in a group of trees, or on the ground in protected locations such as islands or reedbeds. 3-8 eggs are laid. Night herons stand still at the water's edge, and wait to ambush prey, mainly at night. They primarily eat small fish, crustaceans, frogs, aquatic insects, and small mammals. During the day they rest in trees or bushes. There are seven extant species. The genus Nycticorax has suffered more than any other ciconiiform genus from extinction, mainly because of their capability to colonize small, predator-free oceanic islands, and a tendency to evolve towards flightlessness.
