  1. Provide artificial nesting sites for rollers

    A before-and-after study in agricultural habitats in Extramadura, Spain (Avilés & Parejo 2004), found that the number of European rollers Coracias garrulus using artificial nest boxes increased from 29 in 1988 (76% of the 38 boxes available) to 350 in 1991 (55% of 641 available boxes). Nest boxes use varied with habitat: from 68% use in unwooded pasture (256 boxes available) to only 34% in cereal fields with holm oaks (32 boxes). Nest boxes were the same design as in Avilés et al. 2000.
