I am interested in the mechanistic drivers of migration in passerine birds. My thesis will test hypotheses for the evolution of migration by contrasting different types of migrants within the Tyrannus (Kingbird) genus. My fieldwork is focused in northern South America, with field sites in Colombia, Venezuela, and Guyana studying overwintering austral migrant Fork-tailed Flycatchers (Tyrannus savanna). During the off-season I can be found doing morphometric measurements of museum specimens or analyzing geolocator data gathered from the Aves Internacionales collaboration. My ultimate goal is to better understand how seasonal pressures can affect migratory bird populations so that we can better understand how to protect them.
