Map of habitats in the study area.
Nest boxes are represented by blue dots, blue intensity represents occupancy of the nest.
Table 1.
Principal components of the composition of habitat around the kestrel nest.
Table 2.
Total numbers and percentage of prey items delivered by common kestrel Falco tinnunculus parents to the nest over an eight-year study period (2006–2013).
Fig 2.
Quadratic relationship between nest box occupancy and territory landscape heterogeneity (Shannon-Wiener index of habitats) of common kestrels.
Table 3.
Best general linear model (LM) of the occupancy of nests, as a measure of territory quality.
Fig 3.
Relationship between diet diversity (residuals) of common kestrels and territory landscape heterogeneity.
Residuals were extracted by excluding territory landscape heterogeneity from the model.
