About 100,000 bats have fallen from the sky and died during a heatwave in Australia that has left the trees and earth littered with dead creatures.
In scenes likened to "an Alfred Hitchock thought bubble", a heatwave across the north-east state of Queensland in recent days caused mass deaths of flying foxes from an estimated 25 colonies.
Health experts have warned residents not to touch the dead creatures amid concerns about the spread of virus or bites and scratches from bats that may still be alive. At least 16 people have been are receiving antiviral treatment after coming into close contact with a bat.
The stench from the rotting carcasses has begun to disturb residents of Brisbane and large towns. Authorities have dispatched rubbish collectors to pick up thousands of carcasses from populated areas.
The RSPCA said the heatwave could have a devastating effect on the state's wildlife.
"The heatwave was basically a catastrophe for all the bat colonies in south-east Queensland," a spokesman, Michael Beatty, told ABC News.
