One of a few nutcrackers that

and I were chasing around. There was a resident heard of elk near by that was attracting a lot of dumb tourists. There were a few flying around and chattering along with some magpies so we took chase. And after a while managed to hang out with the magpies and nutcrackers for a while before it started getting dark.
There was also some sort of flycatcher, and a weasel too.
