Crows (Corvidae)

Plush-crested Jay (Cyanocorax chrysops) - HBW 14, p. 584

French: Geai acahé German: Kappenblaurabe Spanish: Chara Moñuda
Other common names: Plush-capped/Band-tailed/Urraca Jay

Taxonomy: Pica chrysops Vieillot, 1818, Paraguay.
Forms a species pair, and previously regarded as conspecific, with C. cyanopogon; it has also been suggested that the two form a superspecies with C. dickeyi. Proposed race interpositus (described from Alagoas, in NE Brazil) seems to be based on a female of C. cyanopogon in worn subadult plumage, but possibly a valid taxon. Four subspecies currently recognized.
