Justification of Red List category
Despite the modelled projections suggesting future decline, there has actually been a recent population increase, particularly in East Antarctica (where most of the world population breeds) and the Ross Sea (Southwell et al. 2015a,b, Lyver et al. 2014) and on the southern Antarctic Peninsula south of 66° S (Sailley et al. 2013). The net change in world population is now positive (Lynch and LaRue 2014) and qualify the species to be downlisted as Least Concern.
