Ibis is the common name for any of the long-legged wading birds of diverse genera comprising the subfamily Threskiornithinae of the family Threskiornithidae, characterized by a long, slender beak that curves downward. These stork-like birds belong to the same family as the spoonbills, but the spoonbills have a flat beak that does not curve downward and is somewhat enlarged at the tip. There are about thirty species of ibises, placed into 12 genera.
Overview and description
The ibis family, Threskiornithidae, includes two groups of large terrestrial and wading birds, placed into two subfamilies: the ibises, comprising the subfamily Threskornithinae, and the spoonbills comprising the subfamily Plataleinae.
It was formerly known as Plataleidae. The spoonbills and ibises were once thought to be related to other groups of long-legged wading birds in the order Ciconiiformes, including the storks, the herons, and the bitterns. But recent study suggest that they belong to the Pelecaniformes.[1] Whether the two subfamilies are reciprocally monophyletic is an open question. The South American Checklist Committee's entry for the Threskiornithidae includes the following comment "Two subfamilies are traditionally (e.g., Matheu & del Hoyo 1992) recognized: Threskiornithinae for ibises and Plataleinae for spoonbills; because the main distinction has to do with bill shape, additional information, especially genetic, is required to recognize a major, deep split in the family." ([1])
The ibises (pronounced [ˈaɪbɨ̞sɨ̞z]) 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 hîb.
Folklore
The Sacred Ibis was an object of religious veneration in ancient Egypt, particularly associated with the god, Thoth. 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.[2]
