PIKAs are very successful species (fossils found from Upper Oligocene) populating mountain talus slopes above the timberline. They are hardly visible, mostly when they carry a chunk of grass they collect. Could be recognized by their high-pitched warning sound which is higher than a much larger animal, marmot.
Good lucky shots, Jederick!
Thanks for the info, Paul and luck is the one of the main ingredients in wildlife photography!!
