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?
