Population justification: Although restricted in range and extent of suitable habitat, it is common where it occurs. The population is estimated to number 10,000-19,999 mature individuals, equating to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals. However, this population estimate is preliminary and requires confirmation.

Trend justification: A rapid and on-going decline is suspected, based on the loss of habitat (riparian thickets and forest undergrowth near water) owing to construction of large hydroelectric plants along the entire Tocantins river and most of the Araguaia river (F. Olmos in litt. 2003).
