This is a huge flock! Did you see any evidence of nesting? It looks like there could be a nesting area to the right of the photo, and it looks like there are several yearling Greater Flamingos within the flock. Thanks for posting these photos!
@Summer Tanager I didn't see nests when I was there but they were (almost) definitely a breeding flock because there were younger birds in there. The enclosure also goes back much further than can be seen in the photo.
