Résumé :	Aerial surveys of geese were carried out in July/August 2008 and 2009 in Northeast and North Greenland. Moulting Pink-footed Geese Anser brachyrhynchus had increased considerably in numbers compared to results of similar surveys in 1988 up to three-fold in Jameson Land in 2008 and the range of moulting birds now included North Greenland as far north as land is found. Moulting Barnacle Geese Branta leucopsis showed a similar increase compared to 1988 two-fold in Jameson Land in 2008 although the range was unchanged. The increase in the Pink-footed Goose and Barnacle Goose populations in Greenland is not unexpected as monitoring on the wintering grounds in the British Isles shows continued and marked increases in both populations. A higher number of both moulting Pink-footed and Barnacle Geese in Jameson Land in 2008 compared to 2009 may be the result of a very snow-rich spring in 2008. Breeding and moulting Light-bellied Brent Geese Branta bernicla hrota were found in several smaller concentrations along the North Greenland coasts between Kap Morris Jesup and Holm Land. They were more dispersed than previously recorded, with fewer birds in Kilen, where previously the major part of the population had occurred.
