Endemic to central Mexico, the Black-polled Yellowthroat is only known within four population centers located in the states of Guanajuato, México, and Michocán. Like many other species of yellowthroat, it typically found within riparian and palustrine areas, particularly within reedbeds. It can be visually distinguished from other species of yellowthroat by a longer, narrower bill, a dramatic black mask and dark cap, and overall darker coloration than other members of Geothlypis.
