What is a Guam flying fox?

The Guam flying fox (Pteropus mariannus), also known as the Mariana fruit bat, is a critically endangered species of flying fox in the family Pteropodidae. It is endemic to the Pacific island of Guam, Mariana Islands.

The Guam flying fox is one of the largest bats in the world, with a wingspan of up to 3 feet (0.91 m). It has a dark brown or blackish fur, with a pale face and a long, pointed snout. The Guam flying fox is primarily frugivorous, feeding on fruits, nectar, and pollen from various plants, including fruits of the banyan tree and the mango. It also plays an important role in seed dispersal, contributing to the regeneration of native forests.

Unfortunately, the Guam flying fox has faced significant population declines due to various threats, including habitat loss and degradation, hunting, and predation by introduced species such as the brown tree snake. Conservation efforts are ongoing to protect the remaining population of the Guam flying fox and restore its habitat, with a goal of securing the long-term survival of this unique and ecologically important species.
