Originally posted by WPRESTO The little fellow in the first picture is a PIKA. They like to live in jumbled rocky moraine deposits. They collect grass stalks, preferably with seed heads, and set them out to dry on the rocks, then take them in later to "storerooms" down in the jumble of the moraine. Pikas are lagomorphs = they are in the same group as rabbits & hares rather than being rodents.
The rodent in the last picture is probably a hoary marmot. Marmots are big rodents, perhaps second in size to beavers in North America.
And you're lucky to get such a good image of the pika, They are a bit nervous-quick and tend to be in and out of their maze within rock piles quickly and frequently. I waited about forty minutes to a shot of one, but it kept appearing where the tele was not pointed, and disappearing before I could swing and focus. I did get two images eventually, but no where near as good as your image (chromes, as I recall I was using either a ZX5n or a *ist).
Yes. They were both on the same talus slope. There were five marmots, one female adult and four pups. At least two Pikas, maybe three.
The trick to shooting pikas is to see where they are, climb the rocks and sit or stand in one place for 10-15 minutes. Eventually they will poke their heads up and you can get a shot. There were caches of food stuffed between rocks in a dozen or more places. They don't hibernate like the marmots, they live under the heavy snow burden and eat their stored food.
The marmots will go into hibernation very soon, probably within the month.
