The Rufous Casiornis has a wide range over central South America, from northern Argentina in the south north as far as the Amazon. Although it is generally considered to be an austral migrant to the majority of its perceived Amazonian range, some records from this region are from the austral summer, posing the question as to whether some birds might spend the whole year, and even breed, well north of the main breeding range. This is a mid-sized tyrant flycatcher with largely rufous plumage, relieved by slightly darker wings, and paler posterior underparts. The bill is largely pale with a darker tip.
