The Andersen bare-back flight fox ( Dobsonia anderseni ) is a flying fox from the genus of bare-back ugly dogs ( Dobsonia ). It occurs on the Bismarck Archipelago and on the Admiralty Islands . The type epithet honors the Danish zoologist Knud Christian Andersen (1867–1918).
features
The sizes and weights of five males and three females collected on Manus Island and now in the Australian Museum . The head-trunk length in the males is 153.0 to 187.5 mm, the tail length 27.4 to 32.0 mm, the forearm length 127.2 to 131.4 mm, the shin length 59.5 to 61.4 mm mm, the ear length 26.9 to 28.5 mm and the weight 248 to 258 g. The females are smaller. Their head-trunk length is 131.8 to 136.0 mm, the tail length 22.2 to 40.0 mm, the forearm length 113.6 to 122.0 mm, the shin length 49.3 to 56.2 mm , the ear length 22.0 to 25.6 mm and the weight 135 to 197 g. The fur is very dark. The head is black-brown, almost black. The coat is dark brown. The underside is sepia-colored with a dark ocher-colored wash in the middle of the lower abdomen.
Occurrence
The distribution area of the Andersen bare-backed flying dog extends to the islands of Bagabag , Boang , Dyaul , Emirau , Karkar , Lihir , Manus , Mussau , New Britain , New Ireland , Sakar , Tabar , Tolokiwa and Umboi .
Way of life
In the sleeping caves, the Andersen blackbacked batwing dog forms large colonies. They make a pok-pok-pok sound during the flight . Individuals ready to mate were observed between June and August. Lactating females, often caught outside of the caves with Japanese nets , never carried young with them, while females caught in caves had young with them. The females probably leave the young at the roost while they are looking for food and carry them with them when they are disturbed at the roost.
Systematics
The taxonomic status of the Andersen blackbacked batwing dog is controversial. While Wim Bergmans and Sukaeri Sarbini (1975, 1979 and 1985) assume a species status, Karl F. Koopman (1982) is of the opinion that the Andersen bare-backed flying dog represents a subspecies of the Moluccan bare-backed bat ( Dobsonia moluccensis ).
