Cape cormorant (Phalacrocorax capensis)
The Cape cormorant is an abundant resident of Southern Africa’s shores. Along the KwaZulu-Natal coast, they are found mainly in winter from April to August. Breeding adults are recognised by their glossy green-black plumage and orange-yellow bill-base. They measure about 64 cm. Non-breeding and immature birds are dusky brown with a paler belly.
Single birds and flocks, sometimes consisting of thousands of birds, are found in coastal waters roosting on offshore islands. They often fly in long lines over the sea and fish in flocks.
