Range Description

Anas eatoni has two island subspecies in the southern Indian Ocean: nominate eatoni is confined to the Kerguelen Islands and drygalskyi to the Crozet Islands, both French Southern Territories. On Kerguelen, it occurs only around the coast, less than 20% of the total area (M. Pascal per B. Hughes in litt. 1999). In the 1950s and 1960s, eatoni was introduced to Amsterdam Island (also part of the French Southern Territories), but has not been seen there since 1970 (Ogilvie and Young 1998) and is assumed to have been extirpated. In 1980-1982, the population was estimated at 600-700 pairs on Crozet and, in 1982-1985, at 15,000-20,000 pairs on Kerguelen (Jouventin et al. 1988), but could now be considerably less. Although there is no information on trend, a rapid decline may already be well advanced (A. Green in litt. 1999).
