Black-headed Gulls

RESTORATION OF A BLACK-HEADED GULL (LARUS RIDIBUNDUS) (CHARADRIIFORMES, AVES) COLONY: THE ROLE OF RELEASERS IN THE FORMATION OF A NEW BIRD COLONY

Our study was conducted on the Kiyovo Lake situated within the limits of the town Lobnya (Moscow region). Formerly, the lake had held a large colony of the Black-headed Gull. Since 1996, these gulls ceased to breed at this lake. During 2009 - 2015, we managed to restore the colony by the usage of artificial measures.
