La Golondrina Tijerita Hirundo rustica sigue expandiendo su área de nidificación en Argentina

Abstract

Barn Swallow Hirundo rustica was first recorded nesting in Argentina in the early 1980s, when just a few pairs were found in central-east Buenos Aires province. Since then, the species appears to have spread. Here we present new records from a locality in central Buenos Aires province, providing further evidence of the extension of its breeding range, as well as data concerning parasitism by Shiny Cowbird Molothrus bonariensis on this species and nest occupancy by Grey-breasted Martins Progne chalybea.
