Provide artificial nesting sites for falcons Bird Conservation

A before-and-after study in mixed farmland and woodlands in Alentejo, Portugal (Catry et al. 2007), found that the local population of lesser kestrels Falco naumanni increased by 36% between 2003 and 2006, following the provision of over 450 artificial nest sites over the same period. The number of pairs nesting in artificial sites increased from 29 in 2003 (150 nests available and a total local population of 268 birds) to 121 in 2006 (450 nests and 364 birds in total). Nests included nest boxes, clay pots and multi-cavity “breeding walls” and “breeding towers” (discussed in Franco et al. 2005).
