Provide artificial nesting sites for falcons Bird Conservation

A small study in mixed farmland and woodlands in Alentejo, Portugal (Franco et al. 2005), found that lesser kestrels Falco naumanni used 25% of 36 nesting cavities in two ‘breeding towers’ in 2003. The towers were constructed in 1997 and 1999 but not occupied until 2002, after modifications were made to the nest chambers to create an enlarged nest cavity. Three pairs bred successfully in 2002 in addition to common kestrels F. tinnunculus, rollers Coracias garrulus, barn owls Tyto alba and jackdaws Corvus monedula.
