Blue-winged warbler
Worked the hedge for food but didn't come down to the water.
Vermivora cyanoptera
Blue-winged Warblers have expanded northward as landscapes changed to shrubbier habitats. This northward expansion increased contact and hybridization with Golden-winged Warblers. This hybridization and competition contributes to Golden-winged population declines.
