Slender-billed Curlew

The slender-billed curlew (Numenius tenuirostris) is an extinct species of curlew formerly native to Eurasia and North Africa. Isotope analysis suggests the majority of the former population bred in the Kazakh Steppe despite a record from the Siberian swamps, and was migratory, wintering in shallow freshwater habitats around the Mediterranean. This species has occurred as a vagrant in western Europe, the Canary Islands, the Azores, Oman, Canada, and Japan.

In November 2024, the species was declared globally extinct, with the last irrefutable sighting of the slender-billed curlew identified from Morocco in February 1995.
