Pink-headed Warbler is restricted to the highlands of Guatemala and the neighboring Mexican state of Chiapas. It occurs as a resident mainly above 2000 m, where it is common in oak-alder-conifer forests, in coniferous forest of pine, cypress and fir, but also in shrubby vegetation. The plumage of males and females is similar. The nesting season ranges from March to May. The nest is a globular structure placed on the ground. Outside the breeding season, Pink-headed Warblers join mixed flocks together with other resident and migratory warblers. Pink-headed Warbler is classified as Vulnerable, because of an ongoing loss of habitat caused by a rapidly growing human population.
