This squirrel, which appears to have dyed its fur is the Red-tailed squirrel, Sciurus granatensis (Sciuridae), one of the most conspicuous species of mammals in natural and disturbed environments in the Neotropics, found from northern Costa Rica, Panama, Colombia, Ecuador, Venezuela, Guyana and some Caribbean islands [1].
Red-tailed squirrels are medium-sized. Their color varies greatly across the range of the species, especially in different habitats [2].
Due to the wide phenotypic variation according to fur coloration, Emmons (1990), proposed three phenotypes: the phenotype 1, located in northern Colombia which is characterized by having bright orange-red tail and back, and white belly; phenotype 2, present in the eastern, with the back and tail colored in olive-brown to dark reddish, and orange belly; the phenotype 3 of the west coast of Ecuador and Colombia, with black olive back, legs and feet red to orange, and black-tipped tail [3].
