Two different White Ibises

Above is a comparison of a photo Geoff Malosh took of the Middle Creek White Ibis with a photo of the ibis I took at Conejohela Flats.

Although these pictures show different sides of the bill, Geoff has another picture that shows both sides of the bill are similar in the Middle Creek bird. The dark/light pattern on the bills is quite different, confirming that these are different birds.

Any comments?
