Yellow-bellied Marmots are out of hibernation. I didn’t see any a few weeks ago, but yesterday I saw over a dozen of them on the talus.
The first one spotted lounging on a rock was fairly small, and so was likely a female. Female marmots average about two-thirds the weight of males.
This is a marmot’s time to mate. Here a male is attempting to mount a female, but she just ran off.
A male basks in the midday sun.
