Only one long-distance austral migrant breeds in the South American temperate forest biome: the White-crested Elaenia (Elaenia albiceps chilensis). However, the migratory dates, routes, and wintering locations are poorly known. During the austral summers of 2011-2013, we attached light level geolocators to breeding White-crested Elaenias at the world's southernmost forests, on Navarino Island, Chile. The duration of fall migration of three Elaenias to the Amazonian wintering grounds was 64-96 days, while spring migration was 45-60 days. The average distance between breeding and wintering grounds was 5,932 km, which constitutes the longest migration of a Neotropical austral migrant studied to date. A better understanding of the annual cycle of Elaenias could offer new opportunities to examine the evolution of migration and population regulation of one of Patagonia's most common birds.419-425engAmazoniaBrazilChilemigratory birdsOmora Ethnobotanical Parksub-AntarcticArtigo10.1676/1559-4491-128.2.419WOS:000379447200018Acesso restrito
