Provide artificial nesting sites for songbirds
A replicated trial in the summers of 1983-6 at three streamside sites in Wyoming, USA (Finch 1990), found that house wrens Troglodytes aedon used nest boxes erected at all three sites, whilst tree swallows Tachycineta bicolor used boxes on one site. Clutch mortality was higher in swallows (87% of 29 clutches) than wrens (37-67% for 99 clutches), with interference by wrens occurring in 45% of 29 swallow nests. Wren clutch loss was largely due to predation, although the rate of clutch loss was lower on the site where swallows did not use nest boxes.
