Echolocation is a bat’s prime method of finding food and orienting itself, but it also helps the animals find and keep their mates, according to a new study. Bat calls contain detailed information an individual’s identity, which helps male bats avoid rivals and helps females find their partners.
Like germophobes who avoid the mall during flu season, North America’s most common bat species is changing its social behavior as a result of disease, new research says. Little brown bats, which have been decimated by a fungus known as white-nose, are turning into loners.
Ever wonder exactly where grizzly bears live on this continent? Or where you might find Myotis lucifungus, the fuzzy, adorable little brown bat that is currently threatened with extinction because of white-nose syndrome? Now you can track them on Google Maps, thanks to a new program that aims to plot the location of every single living thing on Earth.
For animals and animal-inspired machines, launching into flight takes lots of energy. Some animals have evolved to achieve air not by accelerating and lifting off, but by jumping and then using their wings or flaps of skin to glide — like sugar gliders, for instance, or grasshoppers. Now a new Swiss robot can do this, too.
The hundreds of millions of bats in the U.S. are in serious trouble, threatened by such hazards as wind turbines and a fungal infection called white-nose syndrome, all while facing the uncertainty of a changing climate. Most bats hide in caves during the day and live in the air at night, making them notoriously difficult to study. But if scientists are going to help them, they need to be able to track them.
