Birdfinding.info ⇒ Thinly distributed and generally declining across most of Cuba, but still locally common in the western mountains. Most readily seen at the Las Terrazas feeding station in the Sierra del Rosario Biosphere Reserve. Also common at Soroa, Viñales, and La Güira National Park. On New Providence it is most often seen in downtown Nassau along Shirley Street.
Cuban Grassquit
Phonipara canora
Endemic to Cuba, where it occurs in brushy woodlands and scrub at all elevations. Trapping for the cagebird trade has depleted it from many areas, though small numbers remain essentially throughout the island. The bulk of the remaining population appears to be west of Havana in the mountains of Pinar del Río and Artemisa.
An introduced population has been established on New Providence in the Bahamas since the 1960s.
Identification
Male is unique: mostly olive above and gray below with a black face and chest and a contrasting, bright-yellow collar that frames the face.
