Summary

The size of home ranges of common kestrels can vary dramatically among individuals. Within the home range, each individual kestrel defends from intruders a small area around the nest that is referred to as territory. Home ranges are dynamic because their size varies across the year. Also, kestrels do not use all habitat types within their home range homogeneously, but show preferences for certain habitats. The first GPS-tracking study reported in this chapter supports early findings, but opens new avenues to improve data collection on habitat use and home-range size estimate. Finally, this chapter shows that the urban environment might not be a particularly suitable home range for kestrels, because the available evidence suggests that urban kestrels have a poorer reproductive performance than rural kestrels.
