"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_.
