  1. Provide artificial nesting sites for songbirds

    A randomised, replicated trial in 1985 in South Carolina, USA (Plissner & Gowaty 1995), found that a 59% of 94 eastern bluebird Sialia sialis nesting attempts were in 23 territories provided with two nest boxes, compared to 41% in 20 territories supplied with a single box. There were no significant differences in the number of eggs, nestlings or fledglings between territory types. When two boxes were used, they were erected less than 24 m apart, allowing a single male to defend both.
