The mainland and Tierra del Fuego populations of the Ruddy-headed Goose have been in serious decline since the 1950s. This species is now considered to be in danger of extinction both in Argentina and in Chile, with the total population in both countries now estimated a only about 1 000 birds (Madsen et al. 2003, Blanco et al. in press). However, the Falklands/Malvinas population of this species has a favourable conservation status (Wetlands International 2002).
