Abstract

I examined habitat use by winter and spring bird communities from 1981 to 1984 in 1-ha even-aged stands managed for Ruffed Grouse (Bonasus umbellus) in central Pennsylvania. Species richness was higher in edges than interiors of stands in both seasons. Edges of clearcut stands were avoided by winter birds but were used extensively by spring birds. In winter, the bird community seldom used the lower stratum near ground level (≤1 m), perhaps due to snow and ice cover. Both winter and spring avifauna foraged extensively on rough-barked overstory trees (e.g., Quercus and Pinus). Vertical strata use was more stereotypic in spring than in winter, whereas tree species use was more stereotypic in winter than in spring. Rough-barked overstory trees, snags, and slash should be retained in even-aged stands.
