Olive-capped Warbler
Setophaga pityophila
Endemic to Cuba and the northern Bahamas (Grand Bahama and Abaco), where it primarily inhabits pine forests. On Cuba, it occurs mainly in the western mountains of Pinar del Río and Artemisa, but sometimes wanders east to the Zapata Swamp region. There is also a separate, smaller population in the far southeastern mountains of Holguín and Guantánamo provinces.
Identification
Medium gray above and pale gray or whitish below, with an olive forecrown and a bright yellow throat that is partly framed by black streaks.
