  1. Provide artificial nesting sites for songbirds

    A study in summer 2001 in a hayfield in southeast Ontario, Canada (Male et al. 2006), found there were no differences in tree swallow Tachycineta bicolor nest-building behaviour or reproductive success between areas with a high density of nest boxes (boxes 20 m apart, average of 5.6 eggs/clutch and 3.4 chicks fledged/nest) or a low density (boxes 28 m apart, average of 5.3 eggs/clutch and 3.7 chicks fledged/nest). A total of 52 nest boxes were erected in a grid, 1.5 m above ground on metal poles, although only 22 were used for analysis.
