Provide artificial nesting sites for songbirds
A replicated trial in 1988-90 in wetlands in Michigan, USA (Lombardo 1994), found that adult and two year-old female tree swallows Tachycineta bicolor used large and small nest boxes with equal frequency (adults used 27% of large boxes available and 19% of small; two year-olds used 19% and 17% respectively), and that there were no significant differences in reproductive success between nest box types. Boxes were all 19.5 cm tall with a 12.4 cm diameter entrance whole and erected on metal poles (greased to deter mammalian predators). Large boxes had a 14 x 14 cm base, small were 10 x 14 cm.
