Barn Swallows keep expanding their breeding range in South America

Abstract: Barn Swallows (Hirundo rustica) breeding in North America traditionally wintered in South America. In the 1980s a small breeding population was found in coastal Argentina and since then the breeding range of Barn Swallows in the country has expanded. Our aims here were to examine the north-western limits of the breeding range of Barn Swallows in Argentina, and to analyse the factors that may determine selection of nesting site by the species. We surveyed and characterised culverts and bridges below roads, whic… Show more

“…When bird populations spread, long-distance pioneering populations are often backfilled by a more slowly advancing front [1][2][3]. The Barn Swallow Hirundo rustica, a globally distributed passerine [4,5], expanded its breeding range an exceptional 7,000 km when it began breeding 35 years ago in its regular wintering range in Argentina [6], subsequently expanding over 500 km from its starting point [7][8][9][10][11]. Trans-hemispheric breeding attempts have occurred previously in related swallows [12][13][14], but only this colonization has lasted.…”

“…Esto ocasiona grandes variaciones en los tamaños de las colonias entre años sucesivos (Mayhew 1958, Shields 1984, Brown & Brown 2013) y dificulta predecir si las Golondrinas Rabadilla Canela formarán colonias reproductivas estables en Sudamérica o si seguirán siendo visitantes estivales con ocasionales intentos de nidificación dispersos. Las Golondrinas Tijerita han colonizado su nueva área de cría de forma centrífuga a partir de lo que parece ser el centro fundador de esta nueva población reproductiva (Fiameni 2001, Morici 2012, Grande et al 2015. Los intentos reproductivos de la Golondrina Rabadilla Canela dispersos en tiempo y espacio y su menor filopatría, sugieren que la expansión geográfica de su área de cría en Sudamérica podría darse mediante diversos focos aislados de nidificación y no mediante un proceso gradual de expansión del borde del área de cría.…”

“…nentales africanas por parte de poblaciones del Atlántico Norte o deberse simplemente al reciente descubrimiento de estas colonias reproductivas (Sutherland 1998, Whittington et al 1999, Underhill et al 2001. En Sudamérica la subespecie de Golondrina Tijerita (Hirundo rustica erythrogaster) que criaba exclusivamente en Norteamérica comenzó a reproducirse en Sudamérica cerca del año 1980 expandiendo su área de cría en Argentina velozmente (Martinez 1983, Idoeta et al 2010, Grande et al 2015. Todos estos casos confirmados constituyen colonizaciones trans-hemisféricas desde el área de cría en el hemisferio norte al área de invernada en el hemisferio sur e involucran especies de aves terrestres que son coloniales y migradoras de larga distancia.…”
