Where does one of South Carolina’s most secretive and mysterious songbirds migrate and spend the winter?
Now we know, thanks to a research project by Audubon South Carolina and our partners. Using cutting edge tracking technology, we tagged Swainson’s Warblers at Audubon’s Beidler Forest Sanctuary and elsewhere across the state and the South.
This species is prized by birdwatchers and difficult for scientists to study because of the dense, overgrown habitat it occupies. Think lowland swamps, canebrakes, and mountainous rhododendron ravines.
This research project, led by Garrett Rhyne, a Louisiana State University-trained ecologist now at the American Bird Conservancy, found that the population of Swainon’s Warblers east of Appalachia take a land-based route through Florida before making a short hop to the Bahamas and Cuba. Birds from the Mississippi Valley and Missouri Ozarks take a riskier path, crossing the Gulf of Mexico to the Yucatán Peninsula.
This kind of migratory connectivity data can help identify threats to habitat and target conservation efforts throughout the species’ range.

All bird handling and research was carried out by permitted professionals through the Bird Banding Lab.
