Double-crested Cormorant Phalacrocorax auritus

This large, black waterbird has white tufts on the sides of its head and a yellow-orange throat. It also has a characteristic crook in its neck. It is found in marine habitats such as estuaries, bays, harbours and inlets.Double-crested Cormorants nest in colonies usually on the ground on rocky, barren islands with sparse vegetation. Nesting colonies can have up to several hundred active nests, though numbers have declined in recent years. Cormorants feed primarily on small schooling fish, diving from the surface to catch them.Threats to this species include human disturbance and depradation by eagles, gulls and crows. Gill-net entanglement and toxic contamination also impact the cormorants.
