A great deal of research has been conducted regarding Titanis walleri over the years. The bird's body has been discussed many times over for many different reasons, but mostly for descriptions of the known skeleton and its relationship to other Phorusrhacids. Beyond descriptions many have studied the age of the birds and their genus. Some of the most cursory treatments of the bird are actually references in papers on the "Great American Interchange" that occurred when South American and North America came into contact with one another for the first time.
