Outline of Final Research Achievements |
Finlayson’s squirrel, Callosciurus finlaysonii, is distributed in lowland forests throughout South-East Asia. Its pelage colour is conspicuous red, black and white. To understand the ecological meaning of the pelage coloration, we measured and compared across different seasons, ages, body weight and sexes. The color characteristics of the pelages did not differ between the sexes, ages, body weight and seasons, which indicate that the unusual pelage colour cannot be explained as social signals. Colour vision tests revealed that C. finlaysonii can discriminate the colour of conspecific white, black, and red pelages from the colour of sympatric other species, which indicate that the pelage colour could be useful clues for species recognition.
