Glossy Ibis are waders with a long curved bill so they can probe the soft mud looking for critters that live there. They hunt by feeling movement with that long down curved bill and are quick snatch up anything that moves. Mostly this includes insects and their larvae, worms, snails and mussels, crabs and crayfish. Every so often fish, amphibians, lizards and snakes are on the menu as well. I have just recently found out that the ibises have been recently found to be more closely related to pelicans than storks. The magic of DNA.
