11-3-2020 KERALA, INDIA - LITTLE CORMORANT (Microcarbo niger)

The Little Cormorant, Microcarbo niger, is a dainty member of the cormorant family, measuring about 50 centimeters in length. In its breeding attire, it boasts a sleek, all-black plumage adorned with white spots and delicate filoplumes on its face, and a modest crest on the back of its head. The non-breeding or juvenile birds display a more subdued brownish plumage, with a small, distinct white patch on the throat.

Distinguishable from the slightly larger Indian Cormorant by its shorter beak and absence of a peaked head, the Little Cormorant has dark eyes and facial skin. Males and females appear similar, though males are generally larger. A rare silvery-grey plumage has been noted in some individuals.

The Little Cormorant frequents a variety of freshwater bodies, from diminutive village ponds to expansive lakes, and occasionally coastal estuaries.

This species is widely distributed across the Indian Subcontinent, extending east to Java. It is absent from the Himalayas, though vagrants have been spotted in Ladakh.

Often seen perched on waterside rocks with wings outstretched, the Little Cormorant forages alone or in small groups. It dives underwater, propelled by webbed feet, to catch fish, which are sometimes stolen by other birds when brought to the surface.

Breeding occurs in trees, often within mixed-species heronries. The breeding season varies regionally, with nests constructed from sticks. Clutch sizes range from two to six eggs, with asynchronous hatching due to incubation starting with the first egg.

The Little Cormorant may be confused with the vagrant Pygmy Cormorants, especially west of the Indus River valley, where their ranges overlap.

Their diet consists mainly of fish, which they catch by diving in shallow waters. They are known to fish in waters less than a meter deep, targeting fish approximately 2–8 centimeters in length.

The Little Cormorant is classified as Least Concern by the IUCN, indicating it is not currently at significant risk of widespread decline.

Near their nests and roosts, Little Cormorants are quite vocal, emitting low roaring sounds, grunts, groans, and a variety of calls including a low-pitched "ah-ah-ah" and "kok-kok-kok".
