Silvery grebe

Podiceps occipitalis

The silvery grebe (Podiceps occipitalis ) is a species of grebe in the family Podicipedidae. It is found in the western and southern part of South America at altitudes of up to 4,000 metres (13,000 ft). Its natural habitat is freshwater lakes but it also feeds in saline lakes.


The silvery grebe is about 28 cm (11 in) in length. There are two different subspecies which differ in the colouring on their head and facial plumes. The southern form has a black cap and the sides of its head are grey. The neck, chest and belly are white while the back is dark grey and the sides and flanks blackish. The beak and feet are black and the eye red. It is similar in appearance to the Junin grebe (Podiceps taczanowskii ).



Biogeographical realms

The silvery grebe nests in Argentina, the Falkland Islands, Chile, and the western parts of Bolivia, Peru, Ecuador and Colombia. It is a migrant in Paraguay and southern Brazil and possibly also in Uruguay. Its habitat is freshwater lakes, lagoons, reservoirs and ponds at altitudes between sea level and 4,000 metres (13,000 ft). In the Andes it is sometimes found foraging on hypersaline lakes and also inhabits saline lakes in Patagonia where it is found in the company of flamingoes.

Population number

The silvery grebe has an extremely wide range and large total population. Although the population trend is downward, the rate of decline is insufficient for the IUCN to rate the bird as "vulnerable" and it is therefore listed as being of "least concern".
