Despite being a wide ranging species a number of aspects of its life history and ecology are yet to be documented. For example, molt and plumage maturation in wild type birds has yet to be recorded. The status of the Texas population along the Rio Grande also warrants investigation. Many believe that it is a "sink" population being sustained only through immigration from birds originating in Mexico. Further research is also needed to determine the extent of inbreeding occurring between domesticated and wild type muscovies (Stai and Searcy 2003, Stai 2005).
