  1. Provide artificial nesting sites for songbirds

    A replicated trial in woodlands, hedges and around villages on Nakano-shima island, Kyshu, Japan (Higuchi et al. 1990), found that Ryukyu robins Erithacus komadori occupied approximately 5% of nest boxes in 1989, but 35% in 1990, possibly because more boxes in 1990 had entrance holes larger than 4 cm (in 1989 only 1% of 175 boxes with entrances <3 cm in diameter were occupied vs. 44% of 25 with entrances over 3.5 cm). Occupation rates varied across habitats, from 17% of 24 boxes in village vegetation to 42% in some bamboo stands.
