Coasts, estuaries, lakes, rivers, and reservoirs. Nests in colonies in trees, on cliffs, or on the ground.
Oriental Stork
Wetlands, flooded rice paddies, rivers, and marshes. Nests on tall trees, utility poles, and artificial platforms.
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.

Essentially silent like all storks; produces loud mechanical bill-clattering at the nest as a greeting display. Chicks beg with hissing and squeaking. Rarely vocalizes otherwise.

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.
Oriental Stork
The oriental stork is one of the most endangered stork species, with fewer than 3,000 individuals remaining in the wild. It was once widespread across East Asia but declined dramatically due to wetland drainage and pesticide use. Reintroduction programs in Japan and Korea have achieved notable success.
