Range: Amazon Basin, Guianas, Etc
In South America, besides the Amazon Basin, the Guianas and the Guiana Shield, the Cocoa Thrush ranges into two areas.
A medium sized disjunct population lives on southeast coastal Brazil; the narrow coastal range is 300 km wide and extends from Alagoas state in the north to southern Rio de Janeiro state, about 2300 km. Another range for the species is in northeast Colombia and southwest Venezuela. It covers parts of the headwaters of the Caribbean-flowing Orinoco River drainage, and adjacent Amazonian headwaters to the Rio Negro flowing southeast into the Amazon's northwest quadrant. This Colombian-Venezuelan range extends to the coast, and is coastal along northern Venezuela, as it is an extension of the range from the Guianas, (western Guyana).
The Cocoa Thrush's range covers the downstream eastern half of the Amazon Basin; in the northeast Basin, it is in Pará and Amapá state with the Guianas. In the southeast Basin, it is in the Tapajos River and Xingu River drainages; also two thirds of the adjacent river system, the lower Araguaia–Tocantins River drainage.
