Abundance of Red-eyed Vireos (Vireo olivacea) relative to foliage density and forest structure.

Abstract

We evaluated the relationship between Red-eyed Vireo (Vireo olivaceus) abundance and foliage density and forest structurein a northern hardwood forest on Douglas Lake, Michigan. We found no relationship between the abundance of Red-eyed Vireos and forest structure complexity. Although our results suggest that Red-eyed Vireo density does not increase with forest structure, as predicted, our sampling protocol and short period that we had for sampling may have been insufficient to identify Red-eyed Vireo distribution patterns relative to forest structure.
