RS, Brazil.
Photo almost at setting sun. This bird is not very easy to spot, but seems to be common within its range.
It is found in marshy areas of north-eastern Argentina, south-eastern Brazil, and Uruguay. It occupies a similar ecological niche to some reed warblers in the far unrelated family Acrocephalidae.
