What does the pika say when it stops munching on cute flowers? “Eeep!” “Eeep!” “Eeep!” These calls may sound the same to us, but they sound very different to pikas. They can even recognize individual pikas by their calls. They also happen to be one of the most territorial animals, frequently involved in chases and fights — kind of like its famous cartoon counterpart, Pikachu. | Center for Biological Diversity

Listen to the call of the pika. Sometimes referred to as rock rabbits, pika calls are used for individual recognition, predator warning signals, territory defense, or as a way to attract a mate. #PeekIntoTheWild | Center for Biological Diversity

The collared pika will make thousands of collection trips during July and August to gather around 12 lb of “haypiles” by the season’s end. 🐇 Bring the sounds of nature into your home this #NationalWildlifeDay and stream #Immersions on discovery . | Science Channel
