An approach to identify factors and levels of nesting habitat selection: A cross-scale analysis of Goshawk preferences | Kanahaukan pesimäaikanen elinympäristönvalinta Ranskassa: Monimittakaavainen lähestymistapa
Nest site selection may result from diverse agents that work on different spatial scales, and a multilevel analysis can offer a more realistic vision of the search image (proximate factors) and of the scale of nesting habitat selection by a species. Cross-scale analyses of nesting habitat preference...

The stepwise logistic regression showed that 4 variables of the nest stand structure (high tree dbhs, high crown volumes, high flight space and short distance to trails) and 2 variables of the landscape surrounding nest trees (low avian prey richness for both 100-500 and 501-2000 g classes) were significant predictors of Goshawk nest site selection (98% of nests correctly reclassified). We hypothesised that Goshawk species choose nest sites on the basis of the overall structural features of the stand, and then focus on a particular nest tree.
