Plegadis is a bird genus in the family Threskiornithidae. The genus name derives from Ancient Greek plegados, "sickle", referring to the distinctive shape of the bill.[1] Member species are found on every continent except Antarctica as well as a number of islands. The glossy ibis is easily the most widespread of the three species. Plegadis contains the following three species:
