Per Wiki: "The yellow warbler (Setophaga petechia, formerly Dendroica petechia) is a New World warbler species. Sensu lato, they make up the most widespread species in the diverse Setophaga genus, breeding in almost the whole of North America and down to northern South America. The genus name Setophaga is from Ancient Greek ses, "moth", and phagos, "eating", and the specific petechia is from Italian petecchia, a small red spot on the skin."
Here is one from migration at Fort Fisher, NC.
I usually get my breeding Yellow Warblers in North Carolina at Meat Camp ESA near Boone. That is where I captured this one. I plan to add other subspecies later when I get one of the red-faced ones in Costa Rica.
