CERON, Gerardo y TREJO, Ana. Description of the diving technique of the Torrent Duck (Merganetta armata) in the Nahuel Huapi National Park, Argentina. Hornero [online]. 2009, vol.24, n.1, pp. 57-59. ISSN 0073-3407.
We describe the Torrent Duck's (Merganetta armata) diving technique from deep and shallow waters in two rivers of the north-western Patagonia, through 36 observations on 3 individuals. We discuss the possibility that this diving technique is a stereotyped behaviour. We relate the feeding behaviour to the habits of the main preys from the area.
