Golden-winged warbler breeding habitat characteristics and nest success in clearcuts in the southern appalachian mountains

摘要

Despite widespread population declines, few studies have sought to quantify nesting habitat and reproductive characteristics of Golden-winged Warblers (Vermivora chrysoptera). We characterized territory and nesting habitat and measured productivity in forest regeneration areas in the Nantahala National Forest, North Carolina, and Cherokee National Forest, Tennessee, during 1997-1998. We located 82 territories and Monitored 23 nests. Golden-winged Warblers occupied young stands with low basal area and annually mowed Daylit roads (roads mowed wider than the track to facilitate drying), and nested in sites with high herbaceous Density compared to unoccupied regeneration areas.
