The Saint Helena hoopoe (Upupa antaios), also known as the Saint Helena giant hoopoe or giant hoopoe, is an extinct species of the hoopoe (family Upupidae), known exclusively from an incomplete subfossil skeleton. The incomplete skeleton, which was found in 1975 by the palaeontologist Storrs L. Olson, consists of both coracoids and the left femur. It is presumed to have become extinct soon after Saint Helena was discovered and colonized in 1502, due to a combination of habitat destruction and the introduction of predators such as black rats, and domestic cats.
