Habitat: Wetland, Coastal, Marine

Habitat

The Little Black Cormorant is mainly found in freshwater wetlands, but will sometimes be found on sheltered coastal waters, and can use relatively small, deep water bodies. It is strongly aquatic, seldom being seen on dry land, but is often seen resting on rocks, jetties and other perches in water.

Behaviour

Most species of cormorants congregate in breeding colonies, but the Little Black Cormorant also regularly forms large flocks at other times. Foraging Little Black Cormorants may occur in flocks of hundreds or possibly thousands, which sometimes feed co-operatively. They have been recorded surrounding schools of fish in open water, and forming a line across marine inlets to catch fish washed out on ebbing tides. Flocks advance across the water’s surface, with birds flying ahead from the rear, alighting and diving in front of the feeding flock.

Feeding

The Little Black Cormorant feeds on fish, crustaceans and aquatic insects. It catches prey underwater, by diving and swimming using its large, fully webbed feet for propulsion. It has special nictitating membranes that cover and protect the eyes underwater. As their feathers are not waterproof, cormorants are regularly seen perched with their wings outstretched to dry after fishing.

Breeding

The Little Black Cormorant nests colonially, often on the fringes of heron or ibis colonies, building large stick nests in the fork of a tree or on the ground. Both sexes share nest-building, incubation and feeding of the young.
