Probably this is White-faced Ibis (Plegadis chihi)- cheek colors just starting to show.
Excerpts from:
http://www.birds.cornell.edu/AllAboutBirds/BirdGuide/
A dark wading bird with a long, down-curved bill, the White-faced Ibis is a western replacement for the Glossy Ibis. Similar in appearance and habits, the two species can be distinguished only by slight differences in coloring of the face and legs.

Glossy Ibis (Plegadis falcinellus)
A dark wading bird with a long, down-curved bill. Although the Glossy Ibis in North America lives primarily along the Atlantic Coast, it also can be found in Europe, Africa, Asia, and Australia.
# White-faced Ibis is extremely similar, but shows a white feather border completely surrounding the face during breeding season, has a red face and eyes, reddish legs or red around leg joints.
