Distribution

Endemic to the Americas.

Endemic to southwestern Mexico; resident on the Pacific coast from the vicinity of San Blas, Nayarit south to Guerrero (Howell and Webb 1995). There appears to be a gap in the distribution of the San Blas Jay in western Guerrero: subspecies nelsoni enters northwestern Guerrero east to La Lagunilla, but the species is not present for a distance of ca 200 km, until Tecpan de Galeana, central coastal Guerrero, where sanblasianus occurs (Hardy and Raitt 1977).

Elevational distribution from sea level up to 1200 m (Howell and Webb 1995).

Reports (including some documented with specimens) from southeastern Arizona (Phillips 1950, Phillips et al. 1964) are best considered to be of birds that escaped from captivity, given that the species is non-migratory, and in view of the vast distance between the expected range of the San Blas Jay and southeastern Arizona (but see Phillips 1986: 52-53 for a contrary view).
