  1. Provide nest boxes for birds

    A replicated study of 48 common starling Sturnus vulgaris nest boxes at two pasture sites in Sweden (Svensson 1991) found that compared to boxes at 1.5 m or 3 m above ground, those at 4.5 m had significantly higher occupancy (100% vs 75%), numbers of eggs (94 vs 55-57) and numbers of hatched young (86 vs 46-53).  Mean date for first egg was also 2.6 days earlier in the highest boxes. Although there was also a greater number of fledged young in the highest boxes (27 vs 11-19), the average number fledged did not differ significantly between heights (3.4 vs 2.3). Wooden nest boxes (50 mm diameter entrance) were put up at the three heights on eight trees at each site. Boxes were inspected throughout the breeding season.
