The Black-necked Palamedea is a large, chicken-like bird with fairly high legs. It reaches a length of 76 to 91 cm. Its primarily gray plumage is generally darker than the plumage of a crested palamedea . The neck is longer and painted black. Between her long toes there is something like a membrane. A sharp spur at the fold of a wing is deftly used for protection.
The Black-necked Palamedea is common in Colombia, south of Cartagena (de Indias) on lakes along the Rio Sinu, and in the north-west of Venezuela around Lake Maracaibo .
The Black-necked Palamedea lives in swamps, lagoons , on the banks of slowly flowing rivers, more often on forests and inundated land from time to time. They graze like other anseriformes and feed exclusively on leaves and other green parts of plants. The black-necked palamedea breeds for a whole year, but the largest number of eggs is laid in October and November. Her nest is a large pile of plant material. In clutch from 2 to 7, but more often from 3 to 5 eggs, which hatch from 42 to 44 days. Hatched chickens have a yellowish-gray downy plumage and a white bottom. These are brood birds that leave their nest in the first days after birth.
