Yellow-legged tinamou
The yellow-legged tinamou (Crypturellus noctivagus) is a species of tinamou found in wooded and shrubby habitats in tropical and subtropical eastern Brazil. This superficially quail-like bird has a grey-brown plumage and two easily separated subspecies. It has declined due to human activities, and is therefore listed as Near Threatened by the IUCN.
