The species is monotypic (Cabot 1992). RPPN Mãe-da-lua.
Figure 2. Two Crypturellus species are common here: C. parvirostris, the Small-billed Tinamou, and C. tataupa, the Tataupa Tinamou. They are morphologically similar. However, according to Mata et al. 2006, the Small-billed has a red bill with a gray tip, and pale orange eyes, while the Tataupa has a pinky red bill and dark brown eyes. Based on this, the bird on the photo appears to be a Small-billed Tinamou.
The bird was nesting close to my house, where I often hear the song of the Small-billed, but not of the Tataupa. This would confirm the species identification (I did not see this bird vocalizing, though).To top of page
