Taxonomy

Taxonomic note

Oxyura jamaicensis and O. ferruginea (incorporating andina) (del Hoyo and Collar 2014) were previously lumped as O. jamaicensis following SACC (2005), and before then were split as O. jamaicensis (incorporating andina) and O. ferruginea following Sibley and Monroe (1990, 1993).

Population justification: The population size has been estimated at 10,000 individuals of andina and 25,000-100,000 of ferruginea (Wetlands International 2014).

Trend justification: The overall population trend is decreasing, although some populations may be stable and others have unknown trends (Wetlands International 2006). This species has undergone a small or statistically insignificant increase over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007).
