- ‘The soprano is so-called because its echo-locater, or ultra-sonic voice, is higher pitched than that of its fellow pipistrelle.’
- ‘Western pipistrelles and Mexican free-tailed bats have staked their own claim on the chutes and shafts.’
- ‘The jerky flight of the pipistrelle gave rise to the ancient name for bats - the flittermouse.’
