Probably shouldnt,,,,, but I am just gonna say one thing.
first off, everyone has had some great points!
I am impressed with his decision. Although it
might have been best to let the hawk eat it's prey, can you imagine the backlash he would have gotten if he did do that, and it was found out? Pigeons are a tough prey item to get, simply because, they are faster than hawks. The only way for the hawk to catch them is when they are not paying attention. If the hawk was successful at capturing it, it is a avid hunter, who likely caught another prey item the same day.
I think the pigeon probably was okay. Pigeons have a large amount of blood, partially due to their high body temperature. Even a small cut means lots of blood, so I do not think the pigeon was injured severely. I would guess it recovered and flew away. I think it was a better choice than trying to train a adult pigeon who has been free to do whatever it's whole life, to live in a cage. a young one though, it would have worked out better. So, was he supposed to let the hawk eat it when the pigeon was coming to him for help? Am I supposed to not chase a hawk away off of one of my birds if it is caught, just so the hawk might not starve?
the pigeon may have been hurt, but not suffering. It was standing without problem. My birds have had cuts, missing toenails, broken legs, a slice in the back, and all have recovered with little intervention. I'm sure that one did the same.
hard to see, but that is a a deep cut, after it was washed out. there was also one under the wing and in the stomack. A little rest and it was flying next week.
