Today, the International Union for Conservation of Nature (IUCN) has officially declared the Slender-billed Curlew (Numenius tenuirostris) extinct, marking the first known global extinction of a formerly widespread migratory bird species whose range included mainland Europe, North Africa, and West Asia. The last confirmed sighting of the species was at Merja Zerga, Morocco, just over thirty years ago, on 25 February 1995.
