Just like an empty zoo, I have no egrets.
Our egrets don't need no stinkin' zoo..... We have 4 or 5 species of them who hang out at the two alligator farms here. They show up near the first signs of Spring, start building nests to win over their woman for the season..... court... get a temporary wedding license, mate... guard the ensuing eggs, then feed the chicks when they arrive until Mom can't stand their aggressiveness (R41X100), then they make sure they can fly, even if that means knocking them out of the nest... Hang around for a few more weeks, then the alligator farms are quiet until the next Spring.(groan)
I've only been to the one in St Augustine. It's fun....I have pretty decent birding photography equipment but even with a phone camera, you can get close enough to them to get some nice pictures.
The farms were created to raise alligators for their skin and meat.... but the birds found out... the gators keep all the crawling predators away... Their eggs... then the chicks.. are safe in the nests because the gators can't climb trees, but they eat anything that walks. So now, the gator farms make more money from the tourists than gator skin or meat.
