"Travelling at 20mph, with wing beats not visible to the human eye and flying mostly at night the bats are notoriously difficult to photograph."Those tongues.
"They are so detailed you can even see the night creatures slurping from the pool with their little pink tongues."
Photos were taken by Kim Taylor of Surrey, England. Here's Kim and his home-made set-up:
He suspended ropes to direct bats to a narrow swooping zone, used an infrared beam that triggered flash bulbs when a bat broke it, and attached a device to his camera that listened for ultrasonic squeaks which opened the shutter.
I love seeing this kind of devotion to a project.
