Huayco Tinamou is one of the most recently-recognized species in South America, recently split from the widespread Red-winged Tinamou Rhynchotus rufescens. Huayco Tinamou differs from Red-winged Tinamou in voice, range, and some minor plumage differences. Huayco Tinamous are found in central and southern Bolivia and northern Argentina, generally on the east side of the Andean crest. It favors grassy mountain ridges from about 1000 to 3300 meters in elevation.
Little research has been conducted on Huayco Tinamou, so many details of its life history remain unknown. However, given the extent of its range, estimated to be in excess of 113,000 km2, BirdLife International has determined it to be a species of Least Concern.
