Most important, welcome to WhatBird.
Second, I think your bird is a Green Heron but there are other candidates like the American Bittern. I am not good at IDing so get more opinions.
Finally, you are in the general discussion section. There is a separate forum where the experts hang out called "help me identify a bird".
Here is a link to get you there, you may want to repost this bird in that forum.
