The bird has pretty long thin legs and is the size of an 8 week old chick.And he is defintely a juvenile birdIt definitely looks like some type of water fowl, but without webbed feet? I think that this bird is a juvenile based on the down feathers. Apparently there are 349 species of bird where you live and none of them look exactly like this but I think that's because it's a juvenile. This is as close as I could get, and it's a type of very small Herron. How big is your bird?
