Pteropus tonganus Quoy & Gaimard

Tongan Fruit-Bat (Pteropus tonganus)

The Tongan Fruit-Bat occurs with several subspecies in an area that stretches from New Guinea to the Cook Islands in Central Polynesia, whereby the form, that can be found in Polynesia, represents the nominate race.

These animals reach a wing span of more than one metre and spend the day more or less sleeping in roosting trees, where they sometimes form giant colonies.

In most parts of its geographic range the species is an important source of protein and is therefore heavily hunted, but also because the Fruit-Bats, being frugivores, can cause enormous damages in fruiting trees. Hence the species has become rare in some parts of its geographic range, in others it has even disappeared completely.

In the Kingdom of Tonga in contrast Tongan Fruit-Bats are considered as property of the royal family and therefore are protected from hunting – a very effective protection.

On the Cook Islands, the eastern most edge of its distribution area, the Tongan Fruit-Bat is called moa kirikiri, which means ‘leather chicken’. On the Fijian Islands it is called beka, bekua (in the west part of Viti Levu), beka dina or doli (on Kadavu).

Emoia cyanura (Lesson)

Blue-tailed Skink (Emoia cyanura)

This ‘species’ in fact isn’t a species in the common sense, it is most probably not monophyletic, that means the species’ name covers more than one species.

The Polynesian populations extend from Fiji into central Polynesia (Cook Islands, Society Islands) and east Polynesia (Tuamotu Archipelago). The western populations may be native, the central and eastern, however, were most probably imported by early Polynesian settlers.

There is still a lot to discover ….
