Despite usually living near running water, and unlike most members of the Ibis family, Waldrapp Ibis doesn't wade. (Wiki/zoo observation)
The genus name Geronticus means "old man" in greek and refers to their wrinkled bald heads, and eremita is a Latin reference to them being "desert hermits". Waldrapp is German for "forest crow". (wiki, several sources)
Thanks to the fossil record, we know that he Waldrapp Ibis (and/or its close ancestor) has been around for at least 1.8 million years!
