Diet and breeding success of long-eared owls in a semi-arid environment

摘要: Abstract Only a few studies, and mostly in temperate climates Europe, have examined the breeding diet of long-eared owls ( Asio otus ) compared to studies cavity-breeding owls, possibly because difficulties reaching nests former. Here we studied population monitoring that at communal roost, every two three months during 2006–2009, semi-arid region Israel. It was found produced more young than most countries Europe. Diet not associated with parameters whereas laying date negatively correlated both clutch size number nestlings. We social voles Microtus socialis fewer birds house mice Mus musculus made up adults roosts. The Israel differ from comprising an important part diet, addition voles.
