Alsophis antiguae
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Antiguan racer faces extinction primarily due to the introduction of non-native predators, particularly black rats and mongoose, which prey heavily on eggs, juveniles, and adults. Habitat destruction from coastal development and tourism infrastructure has further reduced available nesting and foraging areas. The species' extremely limited range on Great Bird Island makes it exceptionally vulnerable to any environmental disturbance or predator incursion.
Habitat
The Antiguan racer inhabits dry coastal scrubland and rocky shoreline areas on Great Bird Island, preferring areas with dense vegetation cover for shelter and hunting. The species utilizes both terrestrial and semi-arboreal microhabitats within this extremely limited 2.5-hectare range.
