Well maybe not so fierce because I have only observed it eating bugs but the Mississippi Kite is fun to watch. They have excellent eye site and are quite capable at capturing flying insects like Dragonflies and beetles. They can put on quite an aerobatic show when when they find a target. They will head off to South America for the winter but I hope they hang out around our house a bit longer.
Shot with my Canon 7d2 and a Tamron 150-600mm lens at 600mm. I rented this lens just to get closer shots of the Kites. Still getting used to the focal length and hoping to get some sharper pictures soon.
