Endangered Species Act Turns 40! Tucson Citizen Scientists Study Endangered Bat

A bat detector gives off a static crackle as a bat zooms by and dodges a mist net by mere inches. Another swoops too low, flying into the net on its way to steal some sugar water from a nearby hummingbird feeder. Research biologists work quickly to untangle the delicate nocturnal mammal, weigh, and measure it before releasing it back into the cool, Sonoran Desert night air.
