Range-wide migratory connectivity for full-cycle conservation of the golden-winged warbler, climate sensitive songbird of the highest conservation concern


July 2013 - December 2016


Golden-winged warblers are a species of conservation concern, as they have experience dramatic population declines in the eastern portion of their breeding distribution, in spite of relatively high nest success. This study is designed to evaluate movements and spatial affiliations of golden-winged warblers outside of the breeding season.
