Have you ever seen a pigeon chasing another pigeon?

I did. In the center square today. I laughed, then tripped. I thought it was so adorable. I don't know it that is some pigeon mating thing, or one was just being a bully, or playing. I always heard pigeons were not so smart, or rat with wings, but nonetheless, it was adorable. One porker pigeon was chasing a skinnier one around, on foot. Other people did not think it was so funny...
