Seeing red

I recently came across these two robins fighting on the pavement. After watching them for a while they moved into some bushes and I managed to get a few shots. Not the best but I thought it was worth sharing. They looked exhausted, I don't know how long they had been fighting but they pretty much just laid on the ground for about half an hour with their feet gripped on each other, The one of the left did not look in a good state as you can see most of the feathers on his head had been removed. I left them well hidden in the bushes, but I don't know what the outcome was.
