Abstract

Migratory birds have highly complex migratory strategies, sensible to various environment changes. The Fork-tailed flycatcher Tyrannus savanna present migratory strategies that differ between populations. The Argentine populations performs austral migration (i.e., trespass the Tropic of Capricorn during the breeding season), while Brazilian populations perform intertropical migration (stay the entire year between the Tropics), both overwintering at northern South America. With their migratory routes defined, the aim of this project is to answer if these routes will be affected and modified by future climate change, and which migratory system will suffer the higher impact. Therefore, a climate model will be produced using presence data with previsions to the years of 2050 and 2070.
