What bird is this?

Not a pet obviously but I'm not sure what category to put this in. We saw this bird in South Orange yesterday, looks like a heron maybe? It was quite large. Picture isn't great, sorry. It was standing very still.

Hard to see, but guessing Egret.

heron. Black capped night heron us my guess. 

Joy is correct.  It is a heron. Unfortunately it or one of its kind has been visiting our pond

It was too big to be a black capped night heron, it was pretty large. Someone else thinks it was a great blue heron. 

Here's a photo from further away but with a tree for scale. Whatever it was I hadn't seen on at the pond before, it was pretty cool.

Their wing span is really big.

ETA - they need space to get aloft.  I chase them away from our pond.

yes - that last pix makes it a great blue. Too big for a night heron.

Definitely a great blue heron.  They are actually pretty common around her in lakes and streams.

It's a great blue heron.  I wonder why s/he's still hanging around here.  I would think it'd be too cold here now.  I hope it makes it through the winter.
