(Portland, OR) -- The Oregon Zoo is raising three of the world's rarest bat pups, helping to bring them back from the brink of extinction. They are Rodrigues Flying Fox pups, so named because of their expressive furry faces and pointy ears. They're native only to the Island of Rodrigues, in the Indian Ocean, where habitat destruction and a cyclone reduced their population to less than a hundred bats in the 1970s. Now, the population has rebounded to around 20-thousand. Zoo visitors can see the babies in the bat cave, located in the Africa Rain Forest exhibit.
