American pikas know a thing or two about getting ready for winter 💪❄️ Though this treeless, rocky slope may appear inhospitable to most, it’s the perfect spot for American pikas to store their gathered foliage for the winter. | National Geographic Animals

Found in rocky mountain areas, American pikas are known for the “haystacks” they create. This well formed pile is composed of plants like grasses, sedges, and thistles that the pika collects and stores as a winter food source. After the built up vegetation has a chance to dry, this little critter will move the haystack inside of its den deep in the rocks for safekeeping. Catch another glimpse of this species during the premiere of the Photo Ark special this Saturday at 10/9pm central on NatGeo W
