Description
The red-legged cormorant is a medium-sized seabird, with a long neck, streamlined body, webbed feet and a long, thin hooked bill. Its body length is 71–76 centimetres (28–30 in), with an average wingspan of 91 cm (36 in). It weighs 1.3–1.5 kilograms (2.9–3.3 lb). There is no sexual dimorphism between the male and female birds. The red-legged cormorant's appearance is unmistakable. Breeding adults have a smoky grey body, with a slightly paler underside. They have scattered areas of white filoplumes behind the eyes and down the neck. The wing coverts have a speckled, silvery grey appearance, followed by broad black wing tips. The tail is also black. The eyes are green, surrounded by sixteen tiny blue marks. The bill is yellow, shading to orange toward the base, the gular skin is a vibrant orange or red. The legs and feet are a striking coral red. Non-breeding adults look similar to breeding adults. They lack the white filoplumes, the wing coverts appear less silvery, but more dark grey, and the bill and gular skin are duller in colouration. Juvenile red-legged cormorants usually possess paler, brown plumage with a speckling of white around the throat. Juvenile plumage colouration can be highly variable between the Atlantic and Pacific coasts. Their eyes are grey and their bills and gular skin range from black to orange. The legs and feet can be a dull orange to a reddish black.

Feeding Habits
Red-legged Cormorant diet primarily comprises fish such as eels and anchovies, along with planktonic crustaceans. Typically foraging alone or in small groups near their nesting sites, they dive 8-10 meters in inshore and shallow offshore waters, often during low tide to efficiently search for prey.
Habitat
Red-legged Cormorant typically inhabits marine coastal environments, favoring areas with rocky cliffs and small offshore islands. They adeptly utilize steep cliff faces, often with small ledges, to construct nests that are well-protected from predators. Nesting sites usually boast sufficient surface area, shelter from strong winds, and a guard against the impacts of sea waves. For foraging, red-legged Cormorant stays predominantly within inshore waters, often not more than 3 km from their nesting colonies and usually in waters of a depth less than 15 meters. The geographical distribution of these birds is primarily on the South American Pacific coast, from central areas to southernmost regions.

General Info
Distribution Area
The red-legged cormorant is native to the coast of South America. On the Pacific coast it ranges from Macabi Island, Peru to Chiloe Island, Chile. There are small isolated populations on the Atlantic coast scattered across Santa Cruz, Argentina. It rarely occurs further south than the Strait of Magellan. Red-legged cormorants nest sparsely on steep rock faces, including coastal cliffs, rocky islets, and sea caverns. They become virtually undetectable against these rocky outcrops by their speckled grey plumage, with the exception of their colourful bills and feet. They forage within inshore bodies of water and in shallow offshore waters.
Species Status
The cormorant is considered to be Near Threatened on the IUCN Red List of Threatened Species.
