Rare Earthtones

By Adam Brock

At one point last spring, I became obsessed with finding a recording of a bird call that I could use as a ringtone… and gave up after a couple hours of coming across bad recordings and paywalls. But now my search has finally come to an end: the Center for Biological Diversity has come out with Rare Earthtones, a collection of free ringtones of the sounds of rare and endangered North American animals.

After perusing their selection for a couple minutes, I ended up springing for something even better than a bird call: a killer whale.
