  1. Provide artificial nesting sites for songbirds

    A replicated, controlled trial in 1999 at a southern beech Nothofagus forest in Maule Region, Chile (Tomasevic & Estades 2006), found that the breeding population densities of thorn-tailed rayaditos Aphrastura spinicauda and house wrens Troglodytes aedon were significantly on higher ten experimental plots, each with five nest boxes installed, compared to ten control plots (4.2 rayaditos/ha and 4.0 wrens/ha vs. 1.0/ha and 1.4/ha for control plots). However, there were no differences in non-breeding season populations. Overall, 22% of boxes were used by rayaditos and 14% by wrens. A further 28% had nesting material in, but no active nest.
