Tulsa River Park Trails - Two Western Kingbirds Attacking A Squirrel (6-18-24)

I first saw the two Western Kingbirds dive bombing the squirrel in the baseball field. The squirrel got on the other side of the fence so I could get some video. I was really confused by the red spot on one of the Western Kingbird. I checked and found out that they all have the red spot, but it only is rarely seen.
