The Thicket Tinamou, also known as the Rufescent Tinamou, is a modestly sized bird, measuring between 27 to 29 cm in length and tipping the scales at approximately 440 grams. Its plumage is a study in earthy tones, with the upper parts presenting a brown hue, intricately barred with blackish markings on the back, rump, and wings. The breast is washed with a warm cinnamon, transitioning to a greyer shade on the belly, while the undertail is a paler affair, adorned with dark barring. A buff supercilium stands out on its brown head, complemented by a distinct ear covert patch. The bill is a muted brownish, and the legs are a striking red.
When attempting to identify the Thicket Tinamou, look for its prominent buff supercilium and the well-defined ear covert patch. The bird's brown head, barred upper parts, and cinnamon breast are key characteristics. Its red legs can also serve as a useful identification marker.
