Winter diet composition of urban long-eared owls (Asio otus) in Rzeszów (SE Poland)
Abstract Diet variation of the long-eared owl (Asio otus Linnaeus, 1758) was investigated on the basis of pellets collected in winter season 2007/2008 from a communal roosting site in a municipal cemetery in Rzeszów (a city in south-eastern Poland). We assumed that the proximity of human settlements...
