Résumé :	Greylag and Pink-footed Geese, breeding in Iceland and wintering in Britain, are popular quarry species for wildfowl hunters. However, the size of the British hunting bag is unknown. By using the Icelandic bag statistics, recoveries of geese shot in Iceland and Britain, and population models developed by Frederiksen et al. (unpubl. b), it is possible to derive indirect estimates of the size of the British bag. The estimates indicated that about 25,000 Pink-footed Geese and 20,000-25,000 Greylag Geese are shot annually in Britain. The proportion of juveniles in the bag appeared to be higher for Greylag Geese (45-50%) than for Pink-footed Geese (about 30%), and in both cases higher than the proportion in the population. Hunting exerts a strong impact on the dynamics of both species, and a bag reporting system should be introduced in Britain to monitor this.
