A replicated study in 1996 in a longleaf pine Pinus palustris forest in eastern Texas, USA (Saenz et al. 1998) found that fitting restrictor plates (steel plates that stop entrance holes being enlarged) to red-cockaded woodpecker Picoides borealis nesting cavities significantly reduced the proportion of holes that were enlarged (and rendered unsuitable) by larger pileated woodpeckers Dryocopus pileatus, compared to control cavities (2% of restrictor plate-fitted cavities enlarged, n = 54; 41% of control cavities enlarged, n = 276). The authors note that preventing hole enlargement may prevent other species, such as American kestrels Falco sparverius and eastern screech-owls Megascops asio, from nesting in woodpecker cavities too.
