A bat paddling water

In March this year, I was fortune to capture grey-headed flying-foxes playing in the water in Australia. The Grey-headed flying-fox is the largest bat species in Australia, and they primarily feed on nectar, pollen, eucalyptus, rainforest trees, and the fruits of vines. Unlike other pollinators such as bees and birds, flying-foxes can transport pollen over longer distances and disperse larger seeds, making them crucial for the health and regeneration of Australia's native forests. According to the Australian Federal Environment Protection and Biodiversity Conservation Act of 1999, the Grey-headed flying-fox is listed as a vulnerable species due to a rapid decline in their population in a relatively short time. During the summer, only on days when the temperature reaches over 30 degrees Celsius, the flying-foxes gather near ponds at sunset. They fly low over the water's surface and wet their bellies in a unique manner. These wet-bellied creatures then land on nearby trees and lick the thirst-quenching water from their fur. In the scorching summer, in some parks in Sydney, you can always witness an incredible spectacle: flying-foxes dipping their bellies into the river at the speed of a dragonfly touching the water. They continuously flap their wings in an attempt to stay cool, and the speed must be just right because bats do not swim, and an accidental water entry can lead to drowning. Capturing flying-foxes playing in the water is extremely challenging. They emerge only as the daylight fades, fly at high speeds, and the ponds are vast. The spot where flying-foxes land in the water is elusive and hard to determine. To capture them, you must use a 400 or 600mm telephoto lens, and your shutter speed needs to be very fast; otherwise, the photos will be underexposed. If you raise the ISO too high, the photos will be filled with noise. Even in such adverse shooting conditions, you only have a brief window of about ten minutes because nightfall is imminent.
