Predictive models of habitat preferences for the Eurasian eagle owl Bubo bubo: a multiscale approach
Habitat preference of eagle owls Bubo bubo were examined through comparing habitat composition around 51 occupied cliffs and 36 non‐occupied cliffs in Alicante (E Spain). We employed Generalized Linear Models to examine patterns of habitat preference at three different spatial scales: nest site (7 k...
