Great Cormorant
A heavyset seabird with a long, thick neck, blocky head, and heavy hooked
bill. The legs are short, the tail fairly long, and the wings
broad.
Adults are blackish overall with white throat and yellowish skin around
the bill. When breeding, adults have a square patch of white on the thigh
and white neck feathers. Juveniles are brownish with a whitish throat and
belly, with some brownish streaking at the edges. Males are typically
larger and heavier than females.
Local Names : Pan Kowwa (Hindi)
Kinnari neerkakka (Malayalam)
Scientific Name : Phalacrocorax carbo
The great cormorant feeds on fish caught through diving. This birds
literally fly under water. Their large webbed feet make excellent paddle
to propel them in pursuit of their prey. They often emerge quite
far from the point they entered the water, leaving observers like me
bewildered.
Once on land it spends significant length of time with its wings spread
allowing its feathers to dry.
The great cormorant often nests in colonies near wetlands, rivers, and
sheltered inshore waters. Pairs will use the same nest site to breed year
after year. It builds its nest, which is made from sticks, in trees.
This cormorant lays a clutch of three to five eggs. The eggs are a pale
blue or green, and sometimes have a white chalky layer covering them.
These eggs are incubated for a period of about 28 to 31 days.
Both parents feed young, by regurgitation. Age at first flight about 50
days; young may return to nest to be fed for another 40-50 days.
