Groundhog whistle call

Описание: Woodchucks use a whistle call to sound the alarm when a predator or other threat is spotted. They don’t alarm nearly as much as other marmots, but they use their whistle enough to have earned the nickname “whistle pig” (although the yellow-bellied marmot shares this nickname in the west). Why do woodchucks sound the alarm even when they live alone? One reason may be that woodchucks usually live close to other woodchucks, and even though they are competing for resources it is still advantageous to all be on the lookout for predators. There is also fascinating evidence that woodchucks listen closely for alarm calls from other small mammals, especially eastern chipmunks (Tamias striatus), and that chipmunks may also use woodchuck alarm calls as an alert system.
