Brewer's Sparrow in the sage brush (I think...)
The Cedar Waxwing picture was also taken at the side of the nature preserve along Teton Park Road (Grand Teton National Park). The Brewer's Sparrow pictures were taken at while we were camping with some friends at Taylor Fork, near Big Sky. Sparrows are by nature tricky to identify (especially for me!) but I did my best to narrow down the list, and feel like it's a close match.
