摘要

Using cameras at artificial ground nests we found no major quantitative differ- ences in species richness or the relative abundance of nest predators photographed in farm/ forest edge and forest-interior sites at five locations in eastern Pennsylvania. Raccoons(Pro- cyon lotor) were the most commonly photographed visitors to nests at both farm/forest edge and forest interior sites, followed by female Baltimore Orioles(Icterus galbula), southern flying squirrels(Glaucomys volans), gray squirrels(Sciurus carolinensis), eastern chipmunks (Tamias striatus), and Gray Catbirds (Dumetella carolinensis).
