via Infocus. The grey-headed flying fox is the largest bat in Australia — and one of the most vulnerable. Once abundant, there are now only around 300,000 left. The main threats include loss of habitat, extreme-temperature events and human persecution (roosting in numbers, eating cultivated fruit and an undeserved reputation for bearing disease brings it into conflict with people). The bat is now protected throughout its range, but its future remains uncertain. Photographer Ofer Levy spent several days in Parramatta Park in New South Wales photographing the bat’s extraordinary drinking behavior.
