not the best photos taken through reflecting glass, at the back of a large aviary, but showing the size comparison of two of the hybrids with demoiselle crane. You can see the bird on the right is using the typical spoonbill sweeping technique while feeding off the ground. The bird on the left is the one with the short bill (it is a little larger than the long-billed hybrids).
See this earlier photo which has a comment thread:
