Alsophis antiguae

Other common names:
sajdaki: Great Bird Island Racer
Remarks: Extinct on Barbuda and the main island of Antigua. Confined to Great Bird Island by the 1980s, but reintroduced to three more offshore islands: Green, Rabbit, and York (Daltry 2006b, 2006c, 2007; Daltry & Mayer 2010). The subspecies sajdaki is thought by some to represent a full species (Hedges, Couloux & Vidal 2009; Wallach, Williams & Boundy 2014), which would render antiguae extinct, however, there is evidence against this proposition (Daltry & Mayer 2010).
Extinct in: Antigua & Barbuda (Antigua, Barbuda).
Distribution (incl. reintroductions): Antigua & Barbuda (Great Bird Island, Green Island, Rabbit Island, York Island).
