The ibises (collective plural ibis[1]; classical plurals ibides[2][3] and ibes[3]) are a group of long-legged wading birds in the family Threskiornithidae. They all have long down curved bills, and usually feed as a group, probing mud for food items, usually crustaceans. Most species nest in trees, often with spoonbills or herons. The word ibis comes from Greek, originally borrowed from Ancient Egyptian hîband also followed from the root hb.
