“This Blue Jay is very common about the woods at Campo Colorado (Salta). It is remarkably tame and inquisitive, and has a great variety of peculiar grating metallic notes. On the sierras of Totoral I likewise met with it; and it is found as far south as Tucuman and Catamarca.” (White.) According to Azara it is abundant in Paraguay and familiar with man, coming a great deal about the houses. The vernacular name there is Acahé.
