what country's only native mammals are 2 types of bats
Before man accidentally and intentionally introduced various mammals into New Zealand, the only native land mammals were two species of native bats.
At least two species of bat are known to feed on other bats: the spectral bat, also known as the American false vampire bat, and the ghost bat of Australia. One species, the greater noctule bat, catches and eats small birds in the air. Predators of bats include bat hawks, bat falcons and even spiders.
