The three-banded warbler (Basileuterus trifasciatus) is a species of bird in the family Parulidae, the New World warblers. It is found in Ecuador and Peru.
Taxonomy and systematics
The three-banded warbler was formally described in 1880 with its current binomial Basileuterus trifasciatus. Some authors have treated it as a subspecies of the golden-crowned warbler (M. culicivorus).
The three-banded warbler has two subspecies, the nominate B. t. trifasciatus (Taczanowski, 1880) and B. t. nitidior (Chapman, 1924).
