Its called an EGRET....many people call them "cranes"
(edit)Wow....Colson...your quick.....if you happen to have a KOI pond...you will hate these birds!!!
There is not a bird you will come to hate more (and love more) than a wild peacock. Our neighborhood is full of them.
Advantages
-----------
1) Good "watch birds", if anyone even walks down the street at night they let you know
2) It's quite cool to look out your picture window in the morning and sometimes see a male peacock showing it's colors, it mesmerizes you
3) Good at keeping bugs out of your plants yards
Those advantages are good enough to make me not entirely hate them, and I like them much more than my wife, who hates them because:
Disadvantages
-------------
1) They poop like a dog (size wise). I've never seen a bird do that.
2) They have a tendency to eat your plants as well as your bugs. We finally have figured out what they will and won't eat (plus I have to keep our garden chicken wired at all times).
3) The loud screeching bothers some people (but not me, reminds me of the Fort).
4) They are very "regal" animals. They will NOT get out of the way of your car, even if it's coming at them at 30 MPH. They wait for you to get out of their way....lol.
All in all, I think it's amazing that we have wild peacocks in our neighborhood, it's just not something you see all the time in Florida. And it's only our U-Shaped street, they don't go anywhere else. I'll take the advantages over the disadvantages (although I wish they didn't eat so many flowers, just have to trial and error to see which one's they don't like, we know now

).
Thank you so much, Colson! That explains why sometimes people around here call them egrets, and sometimes they call them herons.
It's so confusing to this old Ohio farm kid, who doesn't want to teach my kids the wrong names for stuff.

You're welcome! They're one of my favorites here in Florida!
