Yellow-billed Cacique (Amblycercus holosericeus) - HBW 16, p. 747
French: Cassique à bec jaune
Spanish: Cacique Piquiclaro
Other common names: Chisel-billed Cacique/Blackbird; Prevost’s/Chapman’s Cacique (australis)
Taxonomy: Sturnus holosericeus W. Deppe, 1830, Alvarado, Veracruz, Mexico.
Affiliation uncertain. DNA and skeletal data, also nest structure, indicate that this species is not related to true caciques (Cacicus); even its inclusion within present family has been questioned. Genetic distance between nominate race and australis suggests that two separate species may be involved; races appear to differ little in nesting habits and voice; examination of flavirostris required. Three subspecies currently recognized.
Subspecies and Distribution:
- holosericeus (W. Deppe, 1830) - SE Mexico (S Tamaulipas) and across C America S to NW Colombia (Cartagena).
- flavirostris Chapman, 1915 - Pacific lowlands from W Colombia (Chocó) S to N Peru (Tumbes).
- australis Chapman, 1919 - Santa Marta Mts (N Colombia), Sierra de Perijá and coastal mountains of C Venezuela (Distrito Federal), and Andes from SW Venezuela S to Peru and C Bolivia (Santa Cruz).
