These downward trends have prompted researchers to investigate species’ life histories and associated habitats to better understand the necessary components for successful life stages. The Worm-eating Warbler (Helmitheros vermivorum; WEWA) is an interior specialist with little known regarding its post-fledging habitat needs. I used harness-attached radio transmitters to track fledgling WEWAs in the Tennessee River Gorge to study habitat components and daily movements. Results between fledgling location and random points indicate that degrees slope (gradient of a hillside) and leaf litter depth are significant characteristics of juvenile habitat, and that shrub density and herbaceous cover may also be determining factors. Daily movements averaged 49 linear meters and moved down slope. Additional studies will further reveal post-fledging needs and guide conservation actions.","abstract_html":"Declines in Neotropical migratory birds have been observed over the past several decades.
