Cyanocorax yncas | ©Wilmer Quiceno (La Ceja, Antioquia, Colombia)
This long-tailed bird with a short crest is Cyanocorax yncas (Passeriformes - Corvidae), known as Inca jay in English, and Urraca verde, Carriqui verdiamarillo, Chara verde or Urraca querrequerre in Spanish.
This species has many subspecies, all of them with neotropical distribution. Cyanocorax yncas occurs as two disjunct, resident populations: one from just north of the Rio Grande River in southern Texas to north-central Honduras and a second from Colombia and Venezuela south through eastern Ecuador and Peru to Bolivia. The southern Texas population has been the subject of one long-term study .
