I saw this one on the side of the road a couple of years back, and almost hit it as I came around a corner...so I stopped and tried to get it out of the road, and it wasn't prepared to leave its kill...
I drove my car super slowly right up until it disappeared under my bumper, but eventually picked up its kill and flew off!
I once saw a young Red Tail dive bomb a cat. The cat turned and gave him a “what the hell??” look and the hawk decided that maybe this wasn’t meal material and flew off.
Redtails and hawks in general can carry about 1/3 to 1/2 of their weight. The larger female redtails can weigh about 3 pounds or a bit more and can fly off with one pound or so, a sqirrel. When they kill or find dead animals, such as squirrel road kills, they like to eat it on the ground or carry it a short distance to a low tree limb. That's why this one did not want to get out of the road since they are not good heavy lifters.
There is a video of a cat confronting a hawk on the ground. Eventually the hawk flies away with its prey, but had to drop if about 50 feet away. (I won't link the video since the lying title is click bait, which got this SOB 2 million views.)
Owls, on the other hand, are the heavy lifters. Great Horned Owls that are 3 pounds can supposedly carry 8-9 pounds. Cats and small dogs, look out!
There are all kinds of fake videos of hawks carrying large animals. It won't happen.
Great photography!
It's common that hawks get run over as they don't fly out of the way of cars if they have their prey.
My great-grandaddy X50 was a T Rex!
