In Ibisses there is no visual difference between the sxes but males have normaly larger bills as females. Because the bill of the bird on the photo is quite large I would say it´s a male. They live in the Asiatic wetland-walk-through-.aviary together with some waterfowl, several storks, crowned pigeon and some more birds, there is a nice waterfall and a ´hanging´bridge. A samll stream is running throught the aviary
