They are specialized ground-foragers, walking deliberately along the forest floor, constantly flipping over dead leaves and debris with their long bills to...

Range

The Swainson's Warbler breeds across two main populations in the southeastern United States: one along the Atlantic Coastal Plain from southeastern Virginia south through Florida and west to eastern Texas, and another interior population spanning the Mississippi River floodplain from southern Ill...
