Microcarbo

Microcarbo is a genus of fish-eating birds, known as cormorants, of the family Phalacrocoracidae. The genus was formerly subsumed within Phalacrocorax.
Microcarbo has been recognized as a valid genus by the IOC's World Bird List on the basis of work by Siegel-Causey, Kennedy et al., and Christidis and Boles.
As suggested by the name, this genus contains the smallest of the world's cormorants. It is also sister to all other cormorants, having diverged from the rest of the family between 12.8 and 15.4 million years ago.

Taxonomy

The genus Microcarbo was introduced in 1856 by the French naturalist Charles Lucien Bonaparte with the pygmy cormorant as the type species. The name combines the Ancient Greek mikros meaning "small" with the genus name Carbo that was introduced by Bernard Germain de Lacépède in 1789.
The genus contains five species.
