|Black-headed ibis (Threskiornis melanocephalus)|
The ibises ( //) (collective plural ibis;  classical plurals ibides   and ibes ) are a group of long-legged wading birds in the family Threskiornithidae, that inhabit wetlands, forests and plains.  "Ibis" derives from the Latin and Ancient Greek word for this group of birds. It also occurs in the scientific name of the cattle egret, (Bubulcus ibis), mistakenly identified in 1757 as being the sacred ibis. 
Ibises all have long, down-curved bills, and usually feed as a group, probing mud for food items, usually crustaceans. They are monogamous and highly territorial while nesting and feeding.  Most nest in trees, often with spoonbills or herons. All extant species are volant, but two extinct genera were flightless, namely the kiwi-like Apteribis in the Hawaiian Islands, and the peculiar Xenicibis in Jamaica.  The word ibis comes from Latin ibis  from Greek ἶβις ibis from Egyptian hb, hīb.

The African sacred ibis was an object of religious veneration in ancient Egypt, particularly associated with the deity Djehuty or otherwise commonly referred to in Greek as Thoth. He is responsible for writing, mathematics, measurement and time as well as the moon and magic.  In artworks of the Late Period of Ancient Egypt, Thoth is popularly depicted as an ibis-headed man in the act of writing. 
At the town of Hermopolis, ibises were reared specifically for sacrificial purposes and in the serapeum at Saqqara, archaeologists found the mummies of one and a half million ibises and hundreds of thousands of falcons. 
According to local legend in the Birecik area, the northern bald ibis was one of the first birds that Noah released from the Ark as a symbol of fertility,  and a lingering religious sentiment in Turkey helped the colonies there to survive long after the demise of the species in Europe. 
The mascot of the University of Miami is an American white ibis named Sebastian. The ibis was selected as the school mascot because of its legendary bravery during hurricanes. According to legend, the ibis is the last sign of wildlife to take shelter before a hurricane hits and the first to reappear once the storm has passed. 
A short story " The Scarlet Ibis" by James Hurst uses the sable-hued bird as foreshadowing for a character's death and as the primary symbol.
