The large water birds Anhimidae are found in watery areas of the country, but roost in trees more often than their smaller counterparts the Anatidae, a migratory family of water birds, do; these are also found in most areas of Venezuela where there is water. The even smaller Podicipedidae live exclusively in the water; only two species of these live in Venezuela: both are native and live in freshwater. One species of Diomedeidae can be found in Venezuela; they live almost exclusively around water at sea, visiting land to breed.
