Recently, my son and I went to Crandon Park on Key Biscayne for a short outing. He went swimming and I watched the birds. (That's a white ibis.)
I got totally absorbed in a crow v. human drama taking place at a picnic table behind me. A family had brought what looked like shrimps to barbecue for lunch but they wanted to go swimming first. It didn't take long for a couple of crows to start poking (beaking) around and getting into the food. It took the dad several trips out of the water and up the beach before he finally secured the food. I think the crows eventually would have figured out how to access even the coolers, but Nick and I left before it all played out.
