The black-eared warbler or Costa Rican warbler is a species of bird in the family Parulidae. It was previously considered conspecific with the three-striped warbler and the Tacarcuna warbler.
Region
Central America
Typical Environment
Occurs in the montane forests of Costa Rica and western Panama, especially in cloud forests and humid evergreen woodlands. It favors dense understory and edges along streams, landslides, and forest gaps. Birds are most frequently encountered in mossy, shaded habitats with abundant leaf litter and epiphytes. It is typically found in paired territories and often associates with mixed-species flocks in the understory. Human-altered habitats are used only where dense secondary growth mimics natural thickets.

Also called the Costa Rican warbler, this species was split from the three-striped warbler complex and is notable for its dark ear patch. It is a lively understory forager of humid montane forests and often joins mixed-species flocks. It typically stays low to the ground, flicking its tail as it gleans insects from leaves and moss. The species is non-migratory and local to the highlands of Costa Rica and western Panama.

Usually seen in pairs or small family groups, often joining mixed-species flocks in the forest understory. Territorial during the breeding season, with cup nests placed low, often on banks or in dense vegetation. Likely monogamous and attentive to nest concealment.
