The extremely poorly known Barred Tinamou is found in easternmost Colombia and in southernmost Venezuela, with an apparently isolated population in extreme northeast Peru; records purportedly from Brazil are no longer accepted, although the species could still be found there. The species takes its unusual scientific name from the Casiquiare River, which is the type locality. This tinamou has a bright chestnut head and neck, boldly black-barred upperparts, a pale grey foreneck and breast, and black-barred flanks. The Barred Tinamou was discovered in the 1920s, but its tiny range is still comparatively rarely visited by ornithologists, and virtually nothing has been published about the species’ natural history. It inhabits dense lowland forest on sandy soils.
