Check out this whistle pig!! That’s the actual nick name of this hoary marmot. The largest species of ground squirrel in North America comes about this nick name honestly, as when it is startled, it will let out a high-pitched whistle to alert all other marmot in the area of danger! Although it’s hard to tell, this photo was taken in the midst of a very loud whistle! 📸: forrest.galante . . . . . . . #animalsofinstagram #animalplanet #animaloftheday #wild #wildlife #outdoors #animals #wildanimals #conservation #nature #animallovers #instanature #wildgeography #wildlifeonearth #extinctoralive
