Yellow-bellied marmots are back out of hibernation. I think that only the adults are visible at present. Soon there will be mating, and then, after about 30 days of gestation, we will see pups nursing.
A marmot watches the world.
Often only the head of the marmot is seen as it lounges. Here is the full marmot walking. 
And another of it standing up watching something.
Lovely to see!
