![]() Our data validated this capture method for torrent ducks, as we succeeded in capturing individuals of the 3 subspecies in different habitats at different elevations and latitudes. Males were more easily captured than females, because of their greater tendency to fly. We deployed the mist nets across fast-moving deep rivers, along elevational gradients (680–4,200 m). ![]() Each captured torrent duck was banded and 38 opportunistic recaptures events were obtained using the same methodology in the same territories. During the austral winter and spring between 20, we captured 372 torrent ducks in 410 capture events on 8 different rivers in Colombia ( n = 1), Peru ( n = 5), and Argentina ( n = 2). As an active process, the execution of this methodology required the presence of a well-trained, 3-person team. We report on the use and efficiency of an active mist-net method for capturing 3 subspecies of torrent ducks ( Merganetta armata), a territorial and specialized South American waterfowl, in fast-moving rivers of the Andes Mountains.
