About the coprophagy of Waxwings (in the context of mineral feeding deficiency). - G.M. Skvortsova, N.P. Knysh. - Berkut. 18 (1-2). 2009. - P. 210-212.
Three cases of unusual foraging behaviour of wintering Waxwings in Sumy (NE Ukraine) in 2006 and 2009 are described. The birds consumed excrements of Tree and House Sparrows on twigs of bushes. It is supposed that the coprophagy was caused by the deficiency of mineral salts in the monotonous vegetable food. [Russian].
Key words: Waxwing, Bombycilla garrulus, behaviour, foraging.
