  1. Provide artificial nesting sites for woodpeckers

    A replicated trial in 1982-3 in an area of forest clear-cut 12 years previously in Ohio, USA (Petit et al. 1985), found that a total of 34 cavities were excavated in 99 artificial snags erected in autumn 1982. Thirty one of these were probably excavated by downy woodpeckers Picoides pubescens, with the remaining three probably being excavated by hairy woodpeckers P. villosus, red-bellied woodpeckers Melanerpes carolinus or northern flickers Colaptes auratus. Only downy woodpeckers were found roosting in cavities. Excavation rates were highest within 35 m of the edge of the clear-cut. Snags were polystyrene cuboids, 21 x 21 x 237 cm, erected vertically on a fibreglass stake on a 16 m grid.
