Spring migration of waders in the Danube Biosphere Reserve.
Poluda A.M.,,Zhmud M.E.
Migrations of waders in the Danube Delta (the Danube Biosphere Reserve, Кubansky island) were observed during three spring seasons 1987-89. 15 species were recorded, among them Black-tailed Godwit (Limosa limosa) and Ruff (Philomachus pugnax) dominated. Observations were taken during all daylight hours, but active migrations were marked only in the morning hours (88.3% of total numbers). Day migration was observed worse in years with late spring, and terms of the first flocks arrival stood in close connection to the course of spring: 4.04 in 1987, 30.03 in 1988, 12.03 in 1983. Daily main dislocations were recorded along the Danube Delta coast.
