Birds flit everywhere at 11,500 feet, on the slope of Leidy Peak. Perhaps they're enjoying the last days of summer. Steve managed to catch a few of them sitting still. Above is a White-Crowned Sparrow, identified by Sweetbay. Thanks for the help!
Bill S. at Wild in Idaho tells us the photo above is of an immature mountain bluebird, or perhaps a female. I have trouble identifying the little gray ones,
