I’m not super familiar with falcon, it was mostly red tails and sharp shinned hawks where I grew up. Smaller birds were always hyper aggressive with the larger predatory birds. I assumed they were trying to chase the larger birds away from their nest or out of their territory. I’ve never seen a red-tail go after a bird. Its usually snakes, mice, and rabbits.
