Japanese Flying Squirrel Male Competition | Pteromys volans orii

During the breeding season, male Japanese dwarf flying squirrels (Pteromys volans orii) sometimes confront one another, usually in the context of competition for a female. Here, the one above has just snuck up behind the individual below, which made a quick turn to look up at the intruder. The animal looking up was in the midst of enjoying a snack, the flowers of a Japanese alder (Alnus japonica) that are visible in his mouth. A frantic battle between the two males soon ensued.
