Jan Riegert, Auteur ; Matej Loevy, Auteur ; Drahomira Fainova, AuteurWe studied the dietary composition of urban populations of Common Kestrels (Falco tinnunculus) and Long-eared Owls (Asio otus) under fluctuating vole abundance in Ceske Budejovice during 2002-2005. Common Voles were the dominant prey. In poor vo[...]
