Looks like you have some happy finches, too!
It's hard to tell from your photo, but that may be a purple finch at your feeder. They are native and look quite similar to the invasive and often more common house finch.
The house finch has brown streaks on his flank down under his wing, like the one in my photo with the 3 birds. The purple finch is white/ tinged with pink on his flank.
