A small, speckle-backed cormorant that is common and widespread in fresh water. The adult is blackish with a short black crest above the bill. Immatures are brownish with paler underparts. Although they share the same habitat with Great Cormorant, Long-tailed Cormorants can be separated by their much smaller size, red eyes, and proportionately longer tails. Generally, Long-tailed Cormorant avoids the marine habitats of the similar-looking Crowned Cormorant, which has a larger crest, an unspeckled back, and a shorter tail.
This is a small cormorant, 50–55 cm (20–22 in) in overall length with a wingspan of 80–90 cm (31–35 in). It is mainly black, glossed green, in the breeding season. The wing coverts are silvery. It has a longish tail, a short head crest and a red or yellow face patch. The bill is yellow.
The sexes are similar, but non-breeding adults and juveniles are browner, with a white belly. Some southern races retain the crest all year round.
This is a common and widespread species, and is not considered to be threatened. It breeds on freshwater wetlands or quiet coasts.
The reed cormorant can dive to considerable depths, but usually feeds in shallow water. It frequently brings prey to the surface. It takes a wide variety of fish. It prefers small slow-moving fish, and those with long and tapering shapes, such as mormyrids, catfishes, and cichlids. It will less frequently eat soles (which can be important in its diet locally), frogs, aquatic invertebrates, and small birds.
Two to four eggs are laid in a nest in a tree or on the ground, normally hidden from view by long grass.
