Its surprising how fast even lower intelligence animals learn that humans can provide food. There is a creek in an urban park nearby where egrets have made a small rookery. The bird spends part of each day just standing on the east end of the fishing area. If you pay it a fish, nearly any creek fish will do, it holds still for you. You can do just about about anything near it eccept touch it and it just waits. Lots of selfie takers with that bird.
