The article provides brief information on observations of grey herons (Ardea cinerea) and great egrets (Ardea alba) in the Lviv and Cherkasy regions during winter. The accounted representatives of the Ardeidae family show a non-mass nature of wintering and were recorded only near water reservoirs not covered with ice. Such observations indicate low synanthropization and the importance of specific habitat types for these birds. In addition, the episodic nature of their detection proves their low resistance to winter conditions, therefore, in rather cold winters, representatives of the Ardeidae family were almost not recorded.
Key words: grey heron, great egret, winter avifauna, urban agglomerations, reservoirs
