Provide artificial nesting sites for falcons
A replicated study in Badajoz, Spain, in 1989 (Aviles et al. 2001), found that European kestrels Falco tinnunculus used 16% of 567 nest boxes placed in seven agricultural and woodland habitats. There were no significant differences in laying date or productivity between habitats. However, when only habitats with more than 15 occupied boxes were analysed, nests in pastures were found to have significantly larger clutch and higher breeding success than those in cereal fields (4.4 eggs/clutch and 4.2 fledglings/nest for 39 nests in pastures vs. 3.7 eggs/clutch and 3.5 fledglings/nest for 19 nests in cereal fields). Nest boxes were erected on power pylons across the habitat types in spring 1989.
