Scorching heatwaves linked to climate change have caused thousands of Australian bats to drop dead after flapping their wings in a desperate bid to cool off, scientists say.

On one day alone in 2002, up to six per cent of the flying foxes in nine colonies in New South Wales, southeast Australia, died when temperatures hit 42C, according to the study. Most alarming, said the biologists, was the mortality rate among young bats, which was as high as 50 per cent.
