This Prothonotary warbler looks like a bit of spring sunlight with its golden-yellow head and breast set off by blue-gray wings. “Prothonotary” refers to clerks in the Roman Catholic Church, whose robes were bright yellow. To a Prothonotary Warbler, a great breeding habitat features dead snags and trees full of holes, always near water—whether rivers, swamps, or bottomland forests. The Audubon Center at Beidler Forest, South Carolina is home to numerous Prothonotary warblers.
