Ibis

The ibises (pronounced /ˈaɪbɪsɪz/) 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.
