'Rhynchotus is a genus of birds in the tinamou family. This genus comprises two members of the South American family. Scientists in Brazil have also studied the biology of this bird. In a 2023 study, researchers looked at the red-winged tinamou and found that it has a special voice box called a syrinx at the end of its throat. This organ helps the bird make sounds, and both male and female tinamous have the same syrinx shape, which means both sexes make similar types of calls. Tinamous are also important in evolution because they are related to ratites, but they are the only ratites that can still fly today.

Taxonomy

Tinamous are part of the group called paleognaths, which also includes larger birds like ostriches and rheas. Tinamous are important in evolution because they are the only paleognaths that still fly.
