  1. Provide artificial nesting sites for falcons

    A replicated trial at nine mixed agricultural sites in Iowa, USA (Craft & Craft 1996), found that American kestrels Falco sparverius occupied 66% of 56 nest boxes for at least one year between 1989 and 1992, with a maximum of 42% occupied in any one year. Clutches contained an average of 4.4 eggs (49 clutches) and 4.2 chicks fledged on average from each successful box (33 boxes, average of 2.7 chicks/box). These values are similar to previously recorded productivities for American kestrels. Four wooden nest boxes were erected in 1988-9 at each site on pylons, windmills, barns or wooden posts. An additional two PVC boxes were erected in 1990 at each site, plus a final two at one of the sites.
