Provide artificial nesting sites for songbirds
A replicated trial in a tidal swamp forest in Virginia, USA (Blem & Blem 1991), found that prothonotary warblers Protonotaria citrea nested in 27-34% of nest boxes erected in 1987-8 (140-214 boxes available). Warblers appeared to favour boxes on trees near open water that were surrounded by relatively large trees, but orientation and height above ground did not appear to have an effect. Wasps occupied 29-42% of nest boxes, presumably preventing colonisation by warblers. Boxes were 28 × 9 × 6 cm, with a 3.8 cm diameter entrance hole and erected on trees 20-280 cm above ground.
