Two hypotheses have been put forward: the “lack-of-food” suggests that a shortage of food forces individuals to leave their regular winter range and the “breeding output” suggests that unusually large food supplies during the preceding breeding season allows production of a large number of offspring dispersing in winter. According to the breeding output hypothesis, irruptive Snowy Owls (Bubo scandiacus (Linnaeus, 1758)) in eastern North America should not exhibit a lower body condition than individuals in regular wintering regions and individuals on the breeding grounds. Additionally, body condition of irruptive individuals should be unrelated to irruption intensity. Although body condition of juveniles was generally lower than that of adults and improved during the winter, we measured a fair body condition in both juvenile and adult irruptive Snowy Owls across North America. The results showed that Snowy Owls are not in a starving state during winter and that body condition of all age classes was not related to winter irruption intensity. Those results support the breeding output hypothesis suggesting that winter irruptions seem to be primarily the result of a large number of offspring produced when food availability on the breeding grounds is high.</dcterms:abstract> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/51003"/> <dc:contributor>Huy, Steve</dc:contributor> <dc:contributor>Miller, Trish</dc:contributor> <dc:contributor>Curk, Teja</dc:contributor> <dc:contributor>Zazelenchuk, Dan</dc:contributor> <dc:creator>Huy, Steve</dc:creator> <dc:contributor>Therrien, Jean-François</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2020-09-24T06:56:42Z</dc:date> <dc:creator>Robillard, Audrey</dc:creator> <dc:creator>Curk, Teja</dc:creator> </rdf:Description> </rdf:RDF>
