SPOTTED NOTHURA Nothura maculosa
The most commonly encountered of the Paraguayan tinamous, this is an open-country species that remains widespread even in inhabited and agricultural areas. Despite their large size adults have cryptic colouration that enables them to crouch and remain almost invisible in grassy areas, then, when you are about to step on them, they burst into flight with a loud whirring of their wings before touching down a safe distance away.
Much debate exists surrounding the Chaco form of this species, considered by some (including the SACC) to be a separate species the Chaco Nothura Nothura chacoensis. Specimens of "chacoensis" from Argentina have since been proved to be indistinguishable from maculosa, and so the "species" has been called a Paraguayan endemic. Our field observations of what we assume to be Chaco Nothuras in the Dry Chaco area do not show any notable differences from typical maculosa either in appearance or voice. There is some suspicion that Chaco birds are smaller, but this is not a characteristic mentioned in the description of Nothura chacoensis. Given the confusion over what chacoensis is, the fact that it is apparently unidentifiable in the field, and the revised identity of Argentinian chacoensis, we prefer not to recognise chacoensis as a valid species until a thorough review of the specimens has been performed.
