Puerto Rican Tanager

Nesospingus speculiferus

Endemic to Puerto Rico, where it is locally common in wet montane forests of the southwestern Cordillera Central (around Maricao), the Sierra de Luquillo in the northeast, and the Sierra de Cayey in the southeast.  Occurs sporadically in other parts of the island, but leaves much apparently suitable habitat unoccupied.

Identification

Best recognized by its striking two-toned head pattern: blackish-brown, helmet-like cap contrasts with gleaming white throat.  Bull-headed, with a remarkably heavy bill that is either all-dark or two-toned.

Upperparts are mostly warm brown.  Adult’s wing has a small white spot at the base of the primaries.

Underparts are subtly textured: whitish with gray-brown spots or arrowheads on the chest that grade to blurred streaks on the belly.
