We examined how wind and temperature below the thermoneutral zone may reduce the suitability of small, isolated woodlots for permanent resident woodland birds. Carolina Chickadees (Poecile carolinensis) and Tufted Titmice (Baeolophus bicolor) exhibited significantly reduced foraging height in the forest canopy with increasing wind strength. The horizontal area of woodlots frequented by most mixed-species flock members was significantly reduced by the combined effect of wind and temperature. In particular, all mixed-species flock members except female Downy Woodpeckers (Picoides pubescens) were found farther from windward edges of woodlots when wind speeds were higher and temperatures were lower. We conclude that chickadees and titmice may be most affected by abiotic edge effects, both sexes of White-breasted Nuthatch (Sitta carolinensis) and male Downy Woodpeckers intermediately affected, and female Downy Woodpeckers least affected. Our results suggest that effects of wind and temperature may be important to populations of bark-foraging birds inhabiting highly fragmented habitat in the Temperate Zone.
