Phalacrocorax neglectus
The Bank Cormorant is an endangered species restricted to the Atlantic coastlines of Namibia and South Africa’s Northern and Western Cape Provinces, where an abundance of kelp (sea bamboo) occurs. It has a population estimated at only 2,500 breeding pairs (7,500 individuals), declining from an estimated 9,000 breeding pairs in the 1980’s due to human and seal disturbance at breeding sites and a reduced food supply. Away from the breeding colonies (where they often occur alongside other kinds of cormorant) they’re usually only seen alone or in small groups.
While the Bank Cormorant is strictly a marine species it seldom ventures further from the coastline than 10km seawards, where it catches fish, octopus, lobster, shrimp and other invertebrates by diving up to 30m deep and staying submerged for up to 80 seconds.
Bank Cormorants form monogamous pairs, breeding in small colonies of 20-100 pairs at any time of year. The pair works together to construct the large platform nest of seaweed, sticks and feathers glued together by guano on inaccessible rocks on the shore or on islands. The parents take turns to incubate the clutch of 1-3 eggs over a month-long period. The chicks take flight for the first time when they’re 8-10 weeks old but remain dependent on their parents until they’re about 6 months old. Fully grown they weigh about 2kg, measuring around 76cm in length.
