Distribution

The chestnut-crowned becard has two major ranges in South America: the

, mostly the south and center-west, and the Cerrado region of Brazil. The Cerrado range is in southeastern South America and also covers large areas of coastal Brazil; the range goes from southern Northeast Region, Brazil to the Southeast region, and includes the eastern Center-West region. From northeast to southeast, the range extends about 2600 km. The range in the Amazon Basin, (about 3200 km), extends through the center regions of northwest and southwest and avoids most highlands-headwater regions of the very midpoint of the Basin. One of two exceptions is the headwater-upperland bordering southeast Venezuela with western

state of North Region, Brazil, (the Amazon Basin); this disjunct range is 300 km by 900 km. The second exception is Caribbean coastal northern Venezuela, a smaller disjunct range. The Amazon Basin range in the west extends to the Andean foothills and is contiguous from southern Colombia south through all eastern Ecuador, all of eastern Amazonian Peru, and parts of Bolivia, especially the extreme north at the headwater tributaries of the Madeira River. The Madeira River in southwestern Amazonas state Brazil is one southerly range limit, and the Rio Negro is the northwestern Amazon range limit. In the southeast Basin the eastern limit is the lower fourth of the adjacent drainage, the Araguaia- Tocantins River, (the upper fourth being in the SE Brazil Cerrado population). In the southeast Basin, only the downstream half of the river systems are in the contiguous range, (the Tapajós and Xingu Rivers).
