Abstract
The response of a nongame bird community to tree defoliation and mortality caused by gypsy moths was studied during the summers of 1984, 1985, 1987, and 1988 in deciduous forest habitat of eastern West Virginia. Birds and structural vegetation characteristics were sampled on 42 permanent stations. The 1984 and 1985 stations were considered undefoliated because whole tree defoliation did not occur until 1986. The 1987 and 1988 stations were categorized as defoliated or undefoliated based on canopy coverage and snag density values when compared to the pooled 1984 and 1985 station values. Some bird species showed higher frequencies of presence at defoliated compared to undefoliated stations, but no species showed lower frequencies of presence at defoliated stations.
