Last week, one of our collaborators, Emanuel Pérez Bogado, a graduate student in Patricia Capllonch’s lab at the Universidad Nacional de Tucumán, Argentina, saw flocks migrating Fork-tailed Flycatchers in northern Argentina (Tucumán Province). One flock was of about 50 birds, including both adults and first-year individuals. These birds head northwards at this time of year, having spent the austral summer (October-January) breeding across much of central and northern Argentina. They primarily overwinter in the “llanos” (grasslands) of the Orinoco River Basin (e.g., Colombia and Venezuela), where they molt their flight feathers before returning to southern South America beginning in August.
