American Goldfinch - Added To MY Backyard Bird Feeder Visitor Log

We have had a few new visitors to our feeders recently and they're all colored gold.  Or yellow.  They're American Goldfinches and you can see one of them in the photo above.  We have both - what I think are - males and females.  Males with a much more striking gold and the females with their winter plumage.  I snapped the photo above out of kitchen windows one morning recently.  And we knew what it was immediately.  But we went to the Field Guide anyway.  Here's the listing for the American Goldfinch below:

The one you see above is at our squirrel-proof feeder that I've filled with thistle seed. 

Let's call this one the fifth species that we've documented as part of our [backyard bird visitor's log] here on the blog. The other four from this Winter/Spring:

• Red-bellied woodpecker
• House Sparrow
• Male and Female Cardinals
• White-breasted Nuthatch
