As the Saint Lucia oriole is found on a single island, with a range of no more than 620 square kilometers, and has a very small population size of around 1,000, it is extremely vulnerable to any destructive activities within its range. Indeed, the Saint Lucia oriole has become notably less abundant since the first surveys of the species were conducted, with the likely agents of this decline being habitat loss, pesticide use and parasitism by the shiny cowbird (Molothrus bonariensis) (4). Many of Saint Lucia’s forests are being encroached upon by agriculture, with vast areas converted to banana and coconut plantations, and other less favourable habitats, although rainforest habitat is relatively well protected (4) (5). This has also had the adverse affect of increasing the population of the shiny cowbird, as this species favours disturbed, cleared areas, and as many as three quarters of Saint Lucia oriole nests may be parasitised by this species (4) (6). Furthermore, like all other island endemics in the Caribbean, the Saint Lucia oriole is vulnerable to destructive, chance natural events, such as hurricanes, which have the potential to destroy much of the species’ population and habitat within a very short space of time (7).
