Unknown things about bats

According to a study published in the British journal Nature , a group of scientists from Princeton University (USA) said in addition to the ability to locate by sound, large brown bat species (scientific name is Eptesicus fuscus ) there is also a magnetic " compass " inside the body, which helps to accurately orient the flight back to the nest.

Scientists have used a radio receiver to track the flight back to the bat's nest. The "experimental" bats were released in a position about 20 km from their nest and divided into different groups. The first group allowed to fly under normal magnetic conditions correctly identified the direction of the nest. Meanwhile, the other two groups were allowed to fly in conditions that the fake school could not find their way back to. This finding confirms that bats have used the body's natural " magnetic compass " to determine the direction of flight.

The journal Nature also published another study showing that bile-sucking bats called Anoura fistulata live in Ecuador's Andes forest, with a tongue length of 85 mm, 1.5 times longer than their bodies. Bats with this strange tongue type often suck nectar deep in the flower stalk, so they not only rely on nectar but also help pollinate flowers.
