Sound up 🔊! Do Mondays just make you want to scream? Well, you're not alone. American pikas scream all the time. In fact, they're notoriously vocal. They, chirp, sing and scream as a way to protect their territory. We think they do a great job. There is also research that indicates pikas can recognize other individual pikas by their call! So behold, the mighty & otherwise utterly cute roar of the American #pika! The Center has been working to protect squeaky little pikas under the Endangered Species Act since 2007. 🎥: National Park Service
