Résumé :	Capsule The present study investigates the use of a mark-resight procedure to estimate total population size in a local goose population. Using colour-ring sightings of the increasingly scattered population of Light-bellied Brent Geese Branta bernicla hrota from their Danish staging areas, we estimate a total population size of 7845 birds (95% CI: 7252-8438). This is in good agreement with numbers obtained from total counts, emphasizing that this population, although steadily increasing, is still small compared with historic numbers.
