Current status and population dynamics of nominate subspecies of Lesser Black-backed Gull Larus fuscus fuscus in the White Sea
The size of the colonies of the nominate subspecies of Lesser Black-backed Gull Larus fuscus fuscus was monitored annually in Onega Bay of the White Sea in 1989—2006. The total current population in the studied area is about 2,100 pairs or 10% of the world population of this subspecies. During the t...
