Range DescriptionCyanocorax caeruleus is rare to locally common in south-east Brazil (south São Paulo south to Rio Grande do Sul), north-east Argentina (Misiones and north Corrientes). A small number of records exist for Paraguay (Ridgely and Tudor 1989, Chebez 1994, Hayes 1995, J. C. Chebez in litt. 1999), but these are not considered credible (Guyra Paraguay 2004). Populations have apparently declined substantially, particularly in the west of its range, and it is now most common in south-east Brazil (Ridgely and Tudor 1989).
