This is a list of Saint Helena, Ascension and Tristan da Cunha animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE)[a] and continues to the present day.[1]
Numerous animal species have disappeared from Saint Helena, Ascension and Tristan da Cunha as part of the ongoing Holocene extinction, driven by human activity.
Middle Pleistocene remains, but speculated to have survived until settlement due a 1584 mention of doves in the island. It was the fourth largest pigeon ever (after the dodo, Rodrigues solitaire, and Viti Levu giant pigeon) and likely flightless, which would have made it easy prey of humans or introduced mammals.[3]
Most recent remains at Prosperous Bay dated to around 1640. The species nested on the ground and was vulnerable to predation by cats and other introduced mammals.[2]
André Thévet in 1555. It was flightless or a poor flyer and nested on the ground, making it vulnerable to hunting and predation by introduced mammals.[3]
Described from subfossil shells in 1875. It probably disappeared due to habitat modification caused by introduced goats, pigs, and rabbits, or predation by rats, mice, and the centipede Scolopendra morsitans.[13]
^The source gives "11,700 calendar yr b2k (before CE 2000)". But "BP" means "before CE 1950". Therefore, the Holocene began 11,650 BP. Doing the math, that is c. 9700 BCE.
