Abstract

The purpose of this study was to determine (1) whether sapsucker foraging influences local insect diversity and species richness and, if so, (2) which insect taxa are most strongly influenced by the presence of sapwells. Our results suggest that natural Yellow-bellied Sapsucker sapwells are a rich resource patch actively exploited by a wide variety of insect species. ... Together, these observations indicate that, across a variety of habitats, the presence of sapsuckers may strongly influence the size, composition, and spatial distribution of local insect communities, just as they can influence the structure of local bird communities.
