Geronticus eremita (Northern Bald Ibis)

Wikipedia Abstract

The northern bald ibis, hermit ibis, or waldrapp (Geronticus eremita) is a migratory bird found in barren, semi-desert or rocky habitats, often close to running water. This 70–80 cm (28–31 in) glossy black ibis, which, unlike other members of the ibis family, is non-wading, has an unfeathered red face and head, and a long, curved red bill. It breeds colonially on coastal or mountain cliff ledges, where it typically lays two to three eggs in a stick nest, and feeds on lizards, insects, and other small animals.

EDGE Analysis

The Northern Bald Ibis has a very distinctive appearance, with a bare red face, neck and throat and long, narrow feathers projecting from the back of the head and neck, forming a dark ‘ruff’. Unfortunately the numbers have continuously declined over the centuries due to unidentified natural events like climate cooling.
