Weird Heron from Brigantine

This heron was standing far out in the marsh grasses at Brigantine yesterday afternoon. At such a distance, identification proved to be a challenge, especially since its appearance was a bit nonstandard. Great Blue Heron seems like the best bet because of the bird's grim expression and the strip of white feathers extending down the bird's neck from its chin to its abdomen. Nothing clearly contradicts that identification. so I guess I will chalk it up to a common bird at a weird viewing angle.
