Dendroica petechia is a New World warbler species or superspecies; the subspecies group around D. (p.) aestiva is increasingly treated as good species Dendroica aestiva (Yellow Warbler) again. The name for the entire cryptic species complex is Mangrove Warbler, and another group of subspecies is known as Golden Warbler. Sensu lato, they make up the most widespread Dendroica species, breeding in almost the whole of North America and down to northern South America.
