Provide artificial nesting sites for songbirds Bird Conservation

A replicated, controlled, paired sites study in 1985-6 in slash pine Pinus elliotti plantations in Florida, USA (Caine & Marion 1991), found that bird species richness and abundance were significantly higher on three sites with snags and nest boxes installed, compared to control plots without them (6.8 species and 9.5 pairs of birds on experimental plots vs. 3.5 species and 4.5 pairs on control plots). Eastern bluebirds Sialia sialis and great crested flycatchers Myiarchus crinitus were both significantly more abundant on experimental plots, with flycatchers using more small boxes (15 x 15 x 20 cm, nine boxes used) than large (25 x 25 x 50 cm, three used). Sixteen snags (8 m tall pine trunks) were erected evenly across plots, each with a small or large nest box attached.
