Provide artificial nesting sites for falcons
A replicated trial in 1987-91 in mixed agricultural habitats and woodland in Pennsylvania, USA (Rohrbaugh & Yahner 1997), found that American kestrels Falco sparverius used 76% of 130 nest boxes at least once over the five-year study period, with 49% of 259 nesting attempts raising at least one offspring. Kestrels most frequently used unconcealed nest boxes in open habitats away from forested areas, and with a lot of light entering. Nest boxes with southeast orientations were used most frequently. Nesting success was also higher in nest boxes with high light intensities. Nest boxes were 26 × 24 × 33 cm with a 7.6 cm diameter entrance hole and were attached 2.0-6.5 m above the ground.
