The passerine fauna of the wetlands on the North coast of the Black Sea, with emphasis on the Paddyfield Warbler (Acrocephalus agricola)

Schogolev I.



Abstract:

Seven species of passerine (Order Passeriformes, Class Aves) were studied at several wetlands on the North coast of the Black Sea from 1983 to 1997. Each species appeared to be considerably specialized in the kind of habitat it occupied, and as a result there were significant differences in the fauna of the wetlands according to the type of habitat present. Freshwater deltas are richest in species, despite varying water levels, while coastal sea water sand bars were occupied by only one species, the Paddyfield Warbler Acrocephalus agricola septima.
