Tina, hi. I'd like to see the wings of Rusty's yellowish feeder bird; I was thinking Goldfinch as well. We'll have to wait for Rusty's next photo!
Rusty and Tina:
Here's a link to a checklist of Wisconsin birds, arranged to go along with your field guide and, most importantly, showing the abundance by season. This is a good tool to narrow down the potential choices.
