Breeding biology of the torrent duck (Merganetta armata armata) in Northwest Patagonia, Argentina

The torrent duck inhabits the rivers of the high Andes, specializing in fast-flowing waters from Venezuela to Tierra del Fuego. In Argentina, the species has been classified as endangered. Because of their high mobility, low density and the challenging terrain, they are difficult to study; however, there is evidence of population declines and loss of successful breeding sites, due to hydroelectric developments, introduced trout and erosion of riverside habitat. This study was designed to provide the first detailed description of the foraging behavior, breeding biology and habitat use of the species.Read Project SummaryBreeding biology of the torrent duck (Merganetta armata armata) in Northwest Patagonia, Argentina
