Breeding conditions:
|
About 50 000 Brent Geese were counted on migration along the coast from 18 May - 4 June. 18 broods of Bean Geese were seen, as well as one nest and one brood of Whooper Swan.
Breeding conditions were favourable, as spring was early without catastrophic returns of cold, and summer (to mid July) without prolonged rains or rapid temperature drop-downs. Reproduction of ground-nesting birds was favoured by low numbers of mammalian predators which are, probably, typical for the area. Poaching and disturbance by fishermen and hunters are the most important negative factors for breeding waterfowl.
