Brown Ibis?

While on a break from my meeting today I spotted these birds (which I had seen before, but this time I finally got a picture that someone besides me could actually see them in). Are these ibis? If they are white ibis they are juvenile but I haven’t seen any white ibis around and honestly this is the first time I have ever seen these birds on our campus. This is about a mile from the Columbia River. Any thoughts?
