Here is a goldfinch followup from our southern neighbor state, and since no photos were posted of Oregon birds. While visiting with my brother last week near San Jose, he pulled out a series of his older bird slides. It was a treat to see the attached photo taken in his backyard. I've never seen such a bird myself although I saw many many hundreds of lesser goldfinches growing up on the San Francisco peninsula. This form was originally called the Arkansas Goldfinch which I had always assumed was because it was first discovered in Arkansas. But their distribution doesn't go nearly that far east. The name comes from their discovery on the headwaters of the Arkansas River in Colorado. Wayne has described their status.

PS, if you enjoy quizzes, how many species do you see at his feeder?
