@silicatefondue @65dBnoise Do you suppose that was a grouse roosting under the snow? I can’t see the tracks on the left well enough to identify.
The tracks on the left looked like a mouse hopping through the fresh snow. It then burrowed under, but the owl still got it. Further up the trail there was another such encounter but with more disrupted snow -perhaps that was a grouse that flapped a bit during the event.
