While it is true that there is a tendency among more southern examples of th 

 species to a more brownish tone of coloration, the difference is far from being sufl 

 ciently constant to warrant their subspecific separation. The extremes of grayne 

 and brownness are shown in specimens from Guayabo, Costa Bica, while the seri 

 from Nicaragua and Panama, respectively, show both styles of coloration.
