During the 1950s and 60s, the natural habitat of Rodrigues Island was extensively cleared for timber, firewood, and farming (5) (6), leaving it one of the most degraded tropical oceanic islands in the world (4), and significantly decreasing the warbler population (5). Then, in 1968, one of the most severe cyclones to ever have hit Rodrigues struck and, with a search in 1969 failing to find any warblers, it was thought to have wiped out one of the island’s endemic birds (5). Thankfully the species had not gone extinct and numbers have since recovered slightly, primarily due to an increase in forest cover through habitat protection and afforestation (5).
However, many threats to this species still remain. Introduced predators, particularly rats, may be limiting the Rodrigues warbler’s ability to recover (5), and cyclones and droughts are a continual potential threat, particularly given the warbler’s restricted location and small population (2) (5). In addition, any further destruction or degradation of the remaining suitable habitat may seriously threaten this species’ existence (2) (6).
