[Immature Dark-eyed Junco]

Crater Lake National Park, Oregon, July 18, 2007

Immature juncos can be trickly due to their stripes. If you have any doubt as to whether its a junco, look at the tail feathers. Of course, this one is an Oregon Junco (oreganus group). Presumably, it is the local subspecies, thurberi (Thurber's Junco).
