Crystal Precision By Mario Cea, Spain

Every night, not long after sunset, about 30 common pipistrelle bats emerge from their roost in a derelict house in Salamanca, Spain, to go hunting. Each has an appetite for up to 3,000 insects a night, which it eats on the wing. Its flight is characteristically fast and jerky, as it tunes its orientation with echolocation to detect objects in the dark.
