- Microcarbo coronatus
Phalacrocorax coronatus
Identification
Length 54 cm, mass 670-880 g; males larger than females.
Breeding adult: Glossy black with white filoplumes on the sides of the head; scapulars and wing-coverts have grey-brown centres. The crest on the forecrown is about 32 cm long and is usually partially erect. The bill is black with a yellow-orange base to the lower mandible; the gape is orange. The eye is red, as is the skin above and in front of the eye.
Non-breeding adult: Paler and browner than when breeding; pare parts duller.
Similar species
Cape Cormorant and Bank Cormorant are larger, have longer bills and shorter tails, and lack the prominent crest. Long-tailed Cormorant is smaller and has a longer tail and shorter legs; its back is more "scaly", and it has a shorter crest.
Distribution
South-western coast of Africa: Namibia and South Africa.
Taxonomy
This species has previously been considered a subspecies of the Long-tailed Cormorant. The Crowned Cormorant has no known subspecies (monotypic[1]).
Placed in genus Phalacrocorax by Clements.
Habitat
Marine coast.
Status
Classified as Near-threatened in the IUCN Red List (BirdLife International, 2007).2
Behaviour
Diet
Forages close to shore, usually in water less than 5-m deep, near rocky shores and in kelp beds. Feeds mainly on benthic fish; also crustaceans, molluscs and worms.
Breeding
Monogamous; breeds in colonies. The nest is a platform of sticks, seaweed, feathers, bones and human debris. One to five eggs are laid at any time of the year and incubated for about 23 days by both adults. Entanglement in fishing line used in the nest structure is a significant cause of chick mortality.
