Phalacrocorax carbo, commonly known as great cormorant are sighted along the water-bodies is generally distinguished from little cormorant (Microcarboniger) in reference to their body size. Only during the breeding season, great cormorants are prominently distinguishable from the later for its breeding plumage. The breeding adults are glossy black, with orange facial skin, white cheeks and throats, white head plumes and white thigh patches, noticeable only during flight. The white head plumes and thigh patches are not present in the blackish-brown non-breeding birds which are easily identifiable from its yellow gular pouch.
