Habitat loss is potentially a significant threat to the Rotuam myzomela, as virtually all primary forest in Rotuma has been cleared for agriculture (2). Fortunately, there is extensive secondary forest which the Rotuma myzomela is able to inhabit (3).
Severe weather, such as cyclones or flooding, also poses a threat to the Rotuma myzomela. Considering its extremely small range, such natural events could have a disastrous effect on the species (3).
As with many species restricted to islands, introduced predators are a constant threat. The Pacific rat (Rattus exulans) is already an invasive species on the island, but its effects on the Rotuma myzomela have yet to be investigated. The introduction of the black rat (Rattus rattus) or domestic cat could have a devastating impact not only on the Rotuma myzomela, but also on Rotuma’s other wildlife (3).
