“…Populations that breed at south‐temperate latitudes in Argentina also overwinter in northern South America (Jahn et al, ) and are thus Neotropical austral migrants (Cueto & Jahn, ). Fall migration patterns (Jahn, Giraldo, et al, ; Jahn, Seavy, et al, ; Jahn et al, ), tracking of environmental conditions (MacPherson et al, ), and, for one site in Brazil, timing of arrival of males versus females (Bejarano & Jahn, ) have been studied in Fork‐tailed Flycatchers, but little is known about spring migration strategies.…”
