Ichthyaetus audouinii (Audouin's Gull)

Synonyms: Larus audouinii (homotypic)

Wikipedia Abstract

The Audouin's gull (Ichthyaetus audouinii) is a large gull restricted to the Mediterranean and the western coast of Saharan Africa and the Iberian peninsula. The genus name is from Ancient Greek ikhthus, "fish", and aetos, "eagle", and the specific audouinii and the English name are after the French naturalist Jean Victoire Audouin. It breeds on small islands colonially or alone, laying 2–3 eggs on a ground nest. As is the case with many gulls, it has traditionally been placed in the genus Larus.
