Provide artificial nesting sites for songbirds Bird Conservation

A replicated study in open farmland in Massachusetts, USA (Ardia et al. 2006), found that tree swallows Tachycineta bicolor occupied 55% of 153 nest boxes provided in 2004, with an average of five eggs/clutch. Swallows preferentially selected east- and south-facing nest boxes before June, but used nest boxes based on availability later in the summer. East- and south- facing boxes heated up faster in the morning, but only early in the breeding season.
