Size

These birds have a length of 23 in (58 cm) and a weight of 726 g (25.6 oz). Their wings could range from 42-50 in (107-127 cm).

Feeding

The American Bittern’s basic food consists of insects, frogs, crayfish, and small fish and animals. When foraging, it mostly relies on stealth, remaining still while waiting for prey to pass by. Its color further contributes to its ability to remain undiscovered by prey. When the bird’s prey is within reach, it lunges forward and seizes it in its bill. After biting or shaking the prey, it is swallowed head first. Foraging microhabitats include forest margins and shorelines. Avoid even-aged stands of older, thick, or dry vegetation.

Habitat

The American Bittern breeds in areas of freshwater wetlands characterized by tall emergent vegetation, shorelines, and vegetative fringes. The bird prefers wetlands created by beavers to those formed by glaciers.

Behavior

Little is known about the species’ migration patterns. Northern populations known to migrate are those that live in places where temperatures can fall below freezing. Southern populations, on the other hand, appear to be non-migratory, inhabiting locations with milder temperatures. The species’ members appear to be largely asocial, having very few pair ties between sexes. Foraging is an entirely solitary activity.
