The Colinus virginianus ridgwayi (colloquially known as the masked bobwhite quail) once dwelled in much of North America, including parts of Arizona and most of the eastern and central United States. However, the bird has not been spotted in the United States since the turn of the twentieth century. Today, a team of biologists at the Buenos Aires National Wildlife Refuge is studying the bird's behavior and genetics with the aim of reintroducing the species to part of its historical habitat. On this Esri Story Map, created by Holly Eagleston of the U.S. Fish & Wildlife Society, readers can learn more about the masked bobwhite quail and the efforts to protect this endangered species. This story map, which features maps, photographs, diagrams, and more, will be of interest to bird lovers as well as those interested in learning more about the work of the Buenos Aires National Wildlife Refuge.
