These little guys are highly entertaining, when you can get them to cooperate. The American Pika is typically found above timberline in talus fields darting up and down and around the big rocks. I’ve found that it is usually best to just plop your butt down in the middle of a spot where they likely are and wait. It doesn’t take long for them to forget you are there and they then go about their business.
This little one popped its head out only 10 feet from me and sat there, contemplating what the big form was intruding on its domain. It quickly backtracked finding another route that wasn’t quite so close.
