I'm on top of the world, 'ey! 🎶 Meet the American Pika! This tiny, mountain-dwelling mammal is often called the “rock rabbit” and is known for its "eeep!" calls and adorable habit of collecting wildflowers to dry into “haypiles” for winter snacks. Pikas are super sensitive to heat and climb to higher elevations as temperatures rise. #WildlifeWednesday #Wildlife #Pika #Mammals #Mountains #PublicLands #Nature #NationalParkService 📸: NationalParkService Images: Pikas in DenaliNPS
