Crows (Corvidae)

Green Jay (Cyanocorax yncas) - HBW 14, p. 585

French: Geai vert German: Inkablaurabe Spanish: Chara Verde
Other common names: Inca Jay ("nominate group")

Taxonomy: Corvus yncas Boddaert, 1783, Chilpes, Junín, Peru.
Formerly placed in a monotypic genus, Xanthoura. Races fall into two groups, one in Central America (first eight listed below), known as the "luxuosus group", and the other in Andes of South America (remaining five races), known as "nominate group"; the groups are sometimes treated as two separate species. Race luxuosus intergrades with vividus in SE Sierra de Tuxtla and Catemaco region of S Veracruz. Proposed race andicolus (Andes of Mérida, Venezuela) subsumed into cyanodorsalis. Thirteen subspecies recognized.

Subspecies and Distribution:

  • glaucescens ( Ridgway, 1900) - extreme S USA (S Texas) and NE Mexico (W Tamaulipas and Nuevo León).
  • luxuosus ( Lesson, 1839) - extreme S USA (lower Rio Grande valley and SE corner of Texas) S through E & SC Mexico (S to Puebla and S Veracruz).
  • speciosus ( Nelson, 1900) - Pacific slope of Mexico in Nayarit and Jalisco.
