Also called the yellow-olive flycatcher, this tyrant flycatcher is widespread across the Neotropics and shows notable vocal and plumage variation, with many described subspecies. It often joins mixed-species flocks and forages quietly by sally-gleaning from foliage. The species builds a distinctive long, hanging purse-like nest with a side entrance, often stitched together with spider silk. Despite complex taxonomy, it remains common across much of its range.
