Knipolegus hudsoni (VAG):breeds in central Argentina, flies north during winter in August and September, and reaches Paraguay,Bolivia and eventually Brazil in MT and MS (Sick, 1997). The Serra do Roncador seems to be the northern limit of its migration (Farnsworth & Langham, 2004d). There are photographic records for MS in April, July and August (WikiAves, 2016).
