The Andean Condor is the largest carrion eating bird in the World and it is found throughout the country. Birds of prey are common in the mountains: buzzards, eagles, hawks and kestrels. In the southern Andes, the guanaco makes an appearance, alongside the deer, Andean foxes and skunks. In the Lake district - in the Magellanic forests - the bird-life is almost oblivious to humans. In the pampas and steppe land of Patagonia many interesting species can be seen. Waterfowl is common, and also the black-necked swans, coscoroba swans and the amusing steamer ducks. The South American version of an ostrich, the rhea, is a peculiar creature, notable because the male single-handedly incubates the eggs and cares for the young. The Atlantic coast and archipelago of Tierra del Fuego are rich in marine life. Occasionally albatross may be seen, skuas, gulls, terns, magellanic penguins. The Valdés Peninsula has colonies of seals, sea lions, penguins and whales can be seen from the shore. The elephant seals arrive late August and start their aggressive breeding display.
