It was pretty fun to watch the Clark's nutcrackers (a mountain jay) steal the dog's food out of the bowl, while intimidating the dog. The dog was an Australian Shepherd, and she would back up a bit, and watch, then dart forward and snap her jaws at the nutcracker. The nutcracker would retreat, then come back in when the dog wasn't looking.
I remember camping in California and there were these huge jays in the mountains....they were blue, but as I recall they were a brighter blue than the Eastern Jays. I thought those were called mountain blue jays or something like that. Neat birds.
