You only list one redwing black bird, but there a few different ones. The one shown is a bi color Red and white. There are All reds, Red-black and yellow, and all Yellow colors on the wings. The colors do not often mix. So if you see a flock they will be the same color. You don't see as many yellow, but all are very common.
