Coasts, estuaries, lakes, rivers, and reservoirs. Nests in colonies in trees, on cliffs, or on the ground.
Shoebill
Freshwater swamps dominated by papyrus and other dense aquatic vegetation in tropical East Africa.
Song & Call Comparison
Great Cormorant
Deep, guttural grunts and 'karrr' calls at colonies. Bill-clicking and hissing in threat displays. Silent at sea. Colonial noise can be deafening during the breeding season.

Largely silent; produces mechanical bill-clattering 'clap-clap-clap' when greeting at the nest — similar to White Stork. Also gives low croaking grunts. Rarely calls in the wild.
Geographic Range & Migration

Central and East Africa from South Sudan and Ethiopia south to Zambia. Largest populations in South Sudan and Uganda.

Massive shoe-shaped bill, one of the largest of any bird — pale yellowish-grey with darker markings
About These Birds
Great Cormorant
The great cormorant is one of the most widespread seabirds in the world. Unlike most waterbirds, cormorants lack fully waterproof plumage, leading to the iconic pose of standing with wings spread open to dry. In Asia, cormorants have been used by fishermen to catch fish for over a thousand years.
Shoebill
The shoebill is one of the most sought-after birds for birdwatchers visiting Africa, prized for its prehistoric appearance and massive bill. It can stand motionless for hours before collapsing forward to seize prey in its enormous bill. Despite standing over a meter tall, shoebills weigh relatively little due to their hollow bones.
