There’s a heat wave in Australia and it’s killing thousands of bats

Campbelltown, home to a large bat colony, is about 36 miles (50 kilometers) southwest of Sydney.

"The temperature hit 46 degrees Celsius and our flying-fox colony went down. WIRES volunteers helped as many as possible," said Ricardo Lonza, founder of Help Save the Wildlife and Bushlands. WIRES is a local wildlife rescue group.

Australia has seven species of flying foxes, which feed on fruit, flowers, pollen and nectar. One of those species is critically endangered and two others are classified as vulnerable, according to the Australian government.

Conservation groups also have been hosing down koalas too keep them cool, as heat stress can severely harm them as well.
