The freshwater wetlands, rivers and lakes of southern South America. Due to the high rainfall in the west and the low evaporation, there is a surprising amount of freshwater flowing and pooling around southern South America.
If there is water, there will be ducks! The family Anatidae contains all of the world's ducks and Geese. The most commonly seen one in southern South America is probably the , 'South American Crested Duck', Lophonetta specularioides. This species looks rather plain at first and from a distance, but a closer look reveals a groovy slicked down hairdo, red eye, freckles and nicely coloured wings.
The 'Black-necked Swan' Cygnus melancoryphus is, despite being the smallest in the Cygnus swan genus, is the largest native waterfowl in South America. It is found in both salt water and freshwater around southern South America.
Grebes are found almost worldwide, including some species in coastal waters, however you will probably notice them more in smaller and stiller freshwater bodies. They look a bit like the Loons of the northern hemisphere, but are more related to flamingoes. They paddle on the surface like a duck, then dive under the water, propelling themselves with their feet, to feed on aquatic invertebrates or fish. The species below is one of the cutest birds you may see in some of the freshwater bodies of southern South America, the 'White-tufted Grebe' Rollandia rolland.
One of the most commonly seen birds right across South America is the 'Southern Lapwing'. They have even adapted to agricultural and urban areas. Their original habitat is open grassy areas, especially along the edge of freshwater, where you can still see them today. No matter what habitat, as soon as you get close, they start making their distinctive 'guard dog' alarm calls. But if you can get close enough you can appreciate the stunning amount of beautiful colours on this species that is often taken for granted. In the image below you can also see the small spur that is displayed when threatened.
