Provide artificial nesting sites for songbirds
Two replicated trials in 1992-4 in woodlots in Ohio, USA (Grubb & Bronson 1995), found that Carolina chickadees Parus carolinensis showed no preference for artificial snags filled with sawdust over those that weren’t filled, but nested more frequently in snags located high above ground (nine snags occupied) and in non-shrub habitat (18% of 38 snags occupied), compared to low snags (two occupied) and in shrub cover (8% of 38 snags occupied). Snags were placed in groups of four (two filled with sawdust and two empty; two in shrub habitat and two in other habitats) or in pairs (one with the entrance 1.2 m above ground, one 3 m above ground). Snags consisted of 1.2-3.08 m sections of 7.8 cm PVC tubing with a nest chamber attached at the top, ‘planted’ in the ground.
