Occupancy and abundance of Little Owl (Athene noctua) in an intensively managed forest area in Biscay
Little Owl (Athene noctua) Science Article 3 abstract We censused a population of Little Owls in Biscay (North Iberian Peninsula) using playback calls.We modelled their distribution using Geographic Information System (GIS), extracting data on land use and landscape composition in occupied and unoccupied areas at two different scales. Little Owl presence and habitat selectionweremainly governed […]

Factors affecting the prevalence of blood parasites of Little Owls Athene noctua in southern Portugal
Little Owl (Athene noctua) Science Article 4 abstract We studied the relationships between occurrence of blood parasites and host traits in a wild population of Little Owls Athene noctua inMediterranean habitats of southern Portugal. Of 39 owls captured between February andAugust 1999, 16 (41.0%)were infected with Leucocytozoon ziemanni. One individual was infected with Trypanosoma sp. […]
Nest Site Habitat and Prey Use of aBreeding Pair of Great Gray Owls in theUpper Peninsula of Michigan
Great Grey Owl (Strix nebulosa) Science Article 3 abstract We describe nest site habitat characteristics at two spatial scales and prey use forthe first confirmed successful nesting pair of Great Gray Owls (Strix nebulosa) inMichigan. Habitats around the nest site were considerably heterogeneous out to 2km, but relatively homogeneous at over 50 m. R. Gregory […]
