I used to think American Goldfinches were unusual. That was before we came to southeast
At the office, we have four feeders filled (and filled and filled) with thistle seed. The Goldfinches particularly enjoy eating at these. Filling the feeders is one of the responsibilities of whoever is staffing the office. Two feeders are filled with black oil sunflower seeds. They attract the Goldfinches, Western Meadowlarks, and Black-headed Grosbeaks. There are other birds feeding there, as well, but they are so shy I haven't been able to identify them, much less get a picture.
A birdhouse on one of our fence posts here houses a family of Barn Swallows.
A pair of Mourning Doves also lives nearby. Sometimes they visit the sunflower seed feeder.
