The first case of nest parasitism of Cuckoo on Sedge Warbler in Kharkov region.

Nadtochiy A.S.

A case of nest parasitism of the Cuckoo (Cuculus canorus) on the Sedge Warbler (Acrocephalus shoenobaenus) was registered first within limits of the city of Kharkov, in floodplain of the Udy river on 19 May 1995. Dimensions of the Cuckoo’s egg were: 20.9 x 16.3 mm, weight 2.86 g. It differed by shell coloration from eggs of the host species but conformed with eggs of the ecological race of Cuckoo that is a nest parasite of the Marsh Warbler (Acrocephalus palustris). The Sedge Warbler is considered as a casual host species for the Cuckoo.
