I wish these had turned out better. The overcast sky's and low light didn't help. This Redtail was defending its territory no matter what size the other bird was. Must be breeding season. The first picture is the redtail attacking a Turkey Vulture and the second he is attacking another larger red-tail. It was awesome to watch this..The last two pictures I was running through the brush and mud so I missed the contact by a fraction of a second, but you get the idea.
