Bats hunt using echolocation, in which they send and receive high frequency sounds to locate prey. when bats hear the sounds of others, they typically begin hunting in the same area. as the number of bats hunting in the area increases, individuals become more successful at locating and capturing prey. some populations of bats live in areas with high levels of noise pollution, such as near heavily trafficked bridges. how might the hunting behavior of bats be affected by such an environment?
