American Bittern

We have had this bird in our yard for 3 days now..... I have seen it fly once, it's wings are gorgeous!
We couldn't figure out what it was. Well, we have confirmation from a neighbor (who is very well educated with animals) that it is a Bittern. According to the MaineBirding site I think it is the American Bittern. My neighbor said it's very unusual that it's in my yard as they are normally very secretive animals. They live in marshes and swamp areas.
It's been eating worms I think pretty steadily here....
I love birds.
