OBSERVACIONES Y COMENTARIOS BIOGEOGRAFICOS SOBRE LA AVIFAUNA DEL ESTE DE LA PROVINCIA DE SAN JUAN, ARGENTINA

Abstract

New records and biogeographic comments on the avifauna of eastern San Juan Province (Argentina Republic). New data on the subtropical avifauna of the E region of San Juan Province are given. 18 of 35 species mentioned in this paper lack weII documented previous records, and tbe information on the remaining 17 is scarce. Comparison of these results with available biogeographic Iiterature a1low us to confirm penetration in San Juan of a subtropical ornitogeograph-ic flow, which folIows xerophytic wood relics of Mountain and Western Chaco districts. This penetration occurs within a wide transition with Monte scrublands.
