  1. Provide artificial nesting sites for songbirds

    A replicated study from over 800 nest boxes across the eastern USA and Canada from 1998-2002 (Cooper et al. 2005) found that eastern bluebirds Sialia sialis used nest boxes across the study area (between 28° and 48° N). However, breeding pairs exhibited higher net reproductive rates in nest boxes at lower latitudes, having on average 17-33% higher likelihood of repeated egg-laying, multiple brooding and successful fledging events than boxes in the northern range (an average of 1.8 broods/box/pair in the south vs. 1.3 in the north). The average number of fledglings was also significantly greater in the south (1.7 vs. to 1.3 fledglings/box/pair).
