The Oriental Cuckoo Probably Breeds in Mt. Rokko

Abstract

On 15 Mag 2004, we found a carcass of cuckoo species, probably depredated, in a forest on Mt. Rokko. We also found a fresh egg with the carcass. The cuckoo was identified as the Oriental Cuckoo Cuculus saturatus by the body size, color pattern of the tail feathers, and characteristic color pattern of the wing-edge. The egg was also identifie das that of the Oriental Cuckoo by its size and shape. Although we did not find a nest parasitized by the Oriental Cuckoo, these facts strongly suggest that the Oriental Cuckoo breeds in the forests of Mt. Rokko, where it has been considered not to breed.
