Could this be a Glossy-black Thrush? The bird was inside the forest, but wasn't timid like I would expect the Glossy-black Thrush to be. 'The Fern' on BirdForum.net wrote a good rationale for Great Thrush: "I'm not 100% certain but think it's great for the following reasons: not pure glossy black, more dull grey, slightly lighter underparts; long tail; dark, reddish brown eye; legs and bill reddish (deep) orange. I might expect glossy black to have more uniform glossy plumage, a shorter tail, perhaps more yellow bare parts and perhaps a lighter or more reddish eye."
d'Orbigny & Lafresnaye, 1837: NOTE(PHY,TAX,PS: Great Thrush is paraphyletic and the four northern forms may be specifically distinct from the nominate as T. gigas. Subspecies gigantodes is phylogenetically closer to T. chiguanco in some analyses. Phenotyp
