A Chinook helicopter flew over a crocodile farm, prompting a mating frenzy among the reptiles, who may have mistaken the noise for a thunderstorm.

You might expect the whirring blades of a helicopter to spark concern or annoyance from animals in the vicinity. But for the reptilian residents of a crocodile farm, a low-flying chopper seemed to signal mating season.

“All of the big males got up and roared and bellowed up at the sky, and then after the helicopters left they mated like mad,” John Lever, owner of the Koorana Crocodile Farm in Queensland, Australia, told ABC.
