Conservationists Use Microphones and Big Data to Count Disappearing Frogs

Many people believe the red-legged frog is the amphibian in Mark Twain's first successful short story, "The Celebrated Jumping Frog of Calaveras County." But it's now on the endangered species list. It was over-hunted; people loved to eat its legs. To get an accurate count of how few of these frogs are left, scientists in Santa Cruz are trying something new. They’re teaming up with a tech company that specializes in big data and sound.
