Medium-sized guan of rainforest canopy. Usually appears entirely dark; note short-legged profile, contrasting red throat patch, and sluggish behavior. Slips quietly through canopy, feeding on fruit; typically found alone or in pairs but may congregate at fruiting trees. Generally wary, especially where hunted, but sometimes tolerates close approach. May be seen seen near the ground at forest edge or along roadsides. Very similar to Spix’s Guan; Marail is smaller and shorter-legged, but this can be surprisingly difficult to judge accurately.
