Formerly placed in a monotypic genus Zarhynchus because of its peculiar bill shape; recent genetic analysis indicates, however, that it belongs to a clade containing the “Andean oropendolas” (P. atrovirens and montane races of P. angustifrons). Two subspecies recognized.

Subspecies and Distribution

  • P. w. ridgwayi (van Rossem, 1934) – E Nicaragua S to W Colombia (E to Serranía de San Lucas) and SW Ecuador (Manabí, rarely to El Oro).
