Northern Cardinal 3 Males

These two were playing "Follow the leader" or harrasing each other, not sure which. The one is much more grey on his back and is a bit slimmer than the other two. The bird on the higher branch seemed to be the boss. The smaller, more grey one followed the other two, but kept to a nearby tree and was 3rd to the feeders. There is a 4th one in a previous spotting who looks different than these 3 because he has a feather sticking out on his right side near his wing.
