Resumen
Migratory birds depend on resources located in distantly separated ecosystems,potentially making them vulnerable to rapid environmental changes across theirrange. Yet, we understand little about how such changes may impact birds indifferent migratory systems, in large part because of a lack of individual-levelresearch throughout their annual cycle and on different continents. The ForktailedFlycatcher (Tyrannus savana) is a widely distributed Neotropical bird,whose nominate subspecies is composed of populations that breed at tropicaland south-temperate latitudes of South America and then spend the nonbreedingseason in northern South America. Using movement data collectedwith light-level geolocators on individual migratory Fork-tailed Flycatchers frombreeding populations at tropical and south-temperate latitudes, we evaluatedwhether different flycatcher populations vary in their vulnerability to futureclimate change. Results suggest that populations breeding at south-temperateand tropical latitudes will lose at least 22% of their breeding area, with most lossesof south-temperate breeding areas occurring in the northern portions of thoseareas. Both south-temperate breeders and tropical breeders will also lose nonbreedingarea, with south-temperate breeders experiencing a loss of over a thirdof their non-breeding area, whereas tropical breeders will lose up to ~16% of thatarea. These results are the first to demonstrate population- and seasondependentrisks to climate change for a migratory bird breeding in theNeotropics, and suggest that mitigating the impacts of climate change forbirds in South America will require conservation planning that accounts forboth seasonal and regional processes.
