Sounds provide important environmental cues
Today’s Video of the Day from the Smithsonian Tropical Research Institute investigates the difference between regular noise and sounds that provide important environmental cues.
While it is known that bats require twice the amount of energy to fly once they become wet, the experts wanted to determine if rain may also hamper their ability to hunt.
The researchers studied two species of bats that hunt in very different ways and at different times of the day.
The team played recordings of heavy downpours and set up surveillance cameras to monitor how the bats would respond.
The study revealed that both bat species relied on sounds to decide whether or not to leave the roost.
