First data on the breeding biology of Barn Swallow, Red-rumped Swallow and House Martin in Corsica Island

This study presents the first data on the breeding biology of three swallow species in Corsica. Breeding parameters of the Barn Swallow and of the House Martin are consistent with data from other Mediterranean populations, showing relatively early breeding that precedes summer drought. In contrast, the Red-rumped Swallow continues breeding during the hottest and driest months. Although seemingly best adapted to Mediterranean summer aridity, its range and population size in Corsica have remained largely unchanged for several decades, unlike the other two species.
