Help me identify this bird.

This bird is one of many I saw in a feeding frenzy in one of my very tall backyard trees. About a half dozen birds around five thirty pm. were swirling and twirling in the area around the top of the trees. I grabbed my camera to take pictures. I thought they were goldfinches due to the yellow bellies, but their heads are quite different and these are much bigger. As you can see, the tails appear to have yellow also. They were very bright yellow on the bellies, which is why they caught my eye.

Possibly a Barn Swallow.
