What were all of these snowy egret doing on the roof of the shelter at the fishing pier at Fort Desoto?
They were waiting for some clueless guy pulling up bait fish and dumping it on the pier before putting it in his bucket. The guy dumped out the fish and then turned his back on the fish to get something out of his cart before he was going to put the bait fish in his bucket. The birds swooped down and had a feast before he realized what was going on and scared them away. There was still plenty of fish left but it was funny to watch.
After the snowy egrets left, Harry, the hybrid great blue heron and great egret, decided to swoop down and grab a fish before they were all picked up.
