The Saint Helena dove (Dysmoropelia dekarchiskos) is an extinct species of flightless bird in the family Columbidae.

[1] It was endemic to the island of Saint Helena in the South Atlantic Ocean.

(USNM 175956) left ulna, (175957 and 175958) proximal fragments of left ulnae, (175959) proximal end of right femur, (175962) distal end of right humerus"[3] It was a fairly large bird with short wings relative to body size and robust legs, with among the most extreme morphological adaptions of flightless columbids, akin to that of the dodo, Rodrigues solitaire and Viti Levu giant pigeon.

However, no accounts of the bird exist (Introductions were made very early on in the history of Saint Helena, and the accounts are therefore less useful) and Lewis (2008) suggests the bird became extinct prior to or during the Last Glacial Maximum.

[2] It has been suggested on morphological grounds that it is most closely related to Streptopelia turtle doves.
