The breeding biology of the Greenland White-fronted Goose (Anser albifrons flavirostris) was studied during two expeditions to Eqalungmiut nunât, West Greenland (67°N) during 1979 and 1984. Nest sites were situated close to or overlooking wetlands whichh constituuted the feeding area of the attendant ganders during incubation. Mean date of clutch initiation in 1984 (11 June) was delayed due to the late spring thaw compared with 22 May in 1979 when spring conditions were more typical of most years.
Nesting occurred significantly more often above 400 m in 1984 than in 1979 when most nesting attempts were below 200 m and the significance of this is discussed. Productivity in terms of brood size and percentage young amongst winter flocks did not differ between 1979 and 1984. Greenland Whitefronts are solitary nesting witth nest densities lower than recorded.
