“…If ≥5 positions were left during a stopover, these were used to estimate the latitude, whereas longitude was estimated using all longitudes during the stopover. All birds followed fall routes that led them far west of the winter site before they made an easterly turn to reach their destination (except for one bird that stayed near the Many species of migrant birds spend a much larger proportion of their life away from than on the breeding area (e.g., Beason et al 2012, Tøttrup et al 2012b). For many of those wintering in tropical Africa and South America, little is known about their basic ecology and behavior during the non-breeding season.…”

“…Even though valuable information has been accumulated over the last century using the ringing method (Greenwood 2009), details about migratory routes and strategies are rarely known. However, the recent development of miniature and light-weight geolocators has dramatically improved the opportunities to obtain whole-year migration tracks of relatively small birds (Afanasyev 2004, Stutchbury et al 2009, Bächler et al 2010, Egevang et al 2010, Åkesson et al 2012, Beason et al 2012, Tøttrup et al 2012 . Even when considering that the positional accuracy is less than that obtained by GPSloggers (Phillips et al 2004), and there is a paucity of latitudinal information during periods around the equinoxes, geolocators allow the mapping of migratory routes, wintering areas and also the estimation of the rate of migration and approximate location and duration of stopover periods (Åkesson et al 2012(Åkesson et al , Tøttrup et al 2012.…”

Red-backed Shrikes likewise first use the Sahel savanna of Sudan for ≤2 months after breeding, before moving farther south for the rest of the winter (Tøttrup et al 2012).…”

“…(2) What is the location and extent of the wintering range of individual Forktailed Flycatchers, and how does the area they occupy in winter compare to that of other passerine migrants? Recent evidence from other migrant passerines demonstrates that at least some occupy more than one area (Heckscher et al 2011, Tøttrup et al 2012, or move throughout winter (Beason et al 2012).…”

Abstract.-Little is known about the timing of migration, migration routes, and migratory connectivity of most of the >230 species of birds that breed at south temperate latitudes of South America and then migrate toward the tropics to overwinter. We used light-level geolocators to track the migration of 3 male and 3 female Fork-tailed Flycatchers (Tyrannus savana) captured on their breeding territories in Argentina. All birds initiated fall migration between late January and late February, and migrated 45 to 66 km day -1 in a northwesterly direction through central South America to either one or two wintering areas. Five individuals first spent several weeks (in April and May) in western Amazonia (mainly Peru, northwestern Brazil, and southern Colombia) before moving east to spend the rest of the non-breeding season in central Venezuela and northern Brazil. One individual occupied primarily one wintering area in eastern Colombia, northwestern Brazil, and southwestern Venezuela. Fall migration took approximately 7-12 weeks to complete and covered a distance of 2,888-4,105 km. We did not analyze spring migration data because of broad overlap with the austral spring equinox. These results are the first data on wintering locations, migration timing, and routes of individual migrant passerine birds that breed in South America. Given the general lack of similar data for practically all migratory birds that breed in South America, geolocator technology has the potential to revolutionize our understanding of how birds migrate-and the threats they face-on South America's rapidly changing landscape. La migración a Larga Distancia de Aves en América del Sur Revelado por GeolocalizadoresResumen.-Poco se sabe sobre la fenología de la migración, las rutas de migración, y la conectividad migratoria de la mayoría de los >230 especies de aves que se reproducen en latitudes templadas del sur de Sur América, y que luego migran hacia los trópicos para invernar. Utilizamos geolocalizadores para estudiar la migración de tres machos y tres hembras de Tyrannus savana capturados en sus territorios de cría en Argentina. Todas las aves iniciaron la migración de otoño entre finales de enero y finales de febrero, y migraron de 45 a 66 km dia -1 hacia el noroeste por el centro de América del Sur, hasta una o dos áreas de invernada. Cinco individuos primero pasaron varias semanas (en abril y mayo) en la Amazonia occidental (principalmente Perú, noroeste de Brasil, y sur de Colombia), antes de moverse hacia el este para pasar el resto de la temporada no reproductiva en el centro de Venezuela y el norte de Brasil. Un individuo estuvo principalmente en un área de invernada en el este de Colombia, noroeste de Brasil, y el suroeste de Venezuela. La migración de otoño duró aproximadamente 7-12 semanas, y cubrió una distancia de 2888-4105 km. No analizamos los datos de la migración de primavera a causa de una amplia superposición con el equinoccio de la primavera austral. Estos resultados representan los primeros datos sobre los lugares de invernad...
