Provide artificial nesting sites for falcons Bird Conservation

A replicated study at reclaimed surface mine sites in West Virginia and Pennsylvania, USA (Wilmers 1982), found that American kestrels Falco sparverius preferentially used nest boxes sited away from a woodland edge; 10 of 65 (15%) woodland edge boxes were used compared with 47% located 50 m or more from a woodland edge. In 1980, 60 nest boxes were erected at 18 mines, and in 1981 a further 91 at 24 mines. Kestrels used 14 (23%) boxes on 10 of 18 (56%) mines in 1980, and 33 of 91 (36%) on 19 of 24 (79%) mines in 1981. Mine sites where boxes were used had significantly less bare ground cover and a deeper litter layer.
