I'm not sure about the ID (American Tree Sparrow) I've given. Just managed this quick shot of a not very pleasant pose before the bird disappeared, but hopefully it will be enough for a definite ID. It was seen at West Thumb Geyser Basin, Yellowstone National Park, on 15 September 2012. Thanks to Matthew and Zunzuncito for correcting my ID. Much appreciated! www.allaboutbirds.org/guide/White-crowned_Sparrow/id
