I do believe I'm enjoying goldfinches as much as I do the hummingbirds! There's one or two of the bright yellow-and-black males at my feeder most any time, and I have counted as many as eight gathered around.
From what I understand by way of the Internet, it looks like my goldfinches are going to pair up and leave for awhile in July or August to raise their families; they will be sorely missed. When they return, they won't be gold again until next year.
They like Niger seed, which makes it costly to keep them in food. But their color and their behavior is worth it. I do hope they stay around for the winter.
