Justification of Red List category
This species has a small range and is experiencing a continuing decline due to the ongoing loss and degradation of its habitat. It is therefore classified as Near Threatened.
Population justification
This species is reasonably common (with encounter rates of 25 birds/hr [Safford 2013]), although less common above 1,000m (Louette 2004). Based on descriptions of abundance, and assuming only a proportion of its restricted range is inhabited, this species is not thought to number more than 10,000 mature individuals. Therefore, it is tentatively placed in the range of 2,500-9,999 mature individuals.
Trend justification
The population is suspected to be slowly declining owing to on-going habitat loss and degradation. Deforestation rates have been low over the past three generations, amounting to 4% (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Given that the species can tolerate degraded areas and clearings, any population decline is likely to be slower than this, therefore the decline is not expected to exceed 5% over three generations.
This species is endemic to Grand Comoro, Comoros.
It is found in forest, as well as clearings and degraded areas on Grand Comore, Comoros (Louette and Herremans 1985).
Its habitat continues to be threatened by destruction for agriculture (Fishpool et al. 2020).
Conservation Actions Underway
A protected area (national park, biosphere reserve or resource management area) on Mt Karthala has been proposed, but is not yet forthcoming (Louette and Stevens 1992, Safford 2001).
Conservation Actions Proposed
Conduct more field surveys to establish the current population, range and status of the species. Develop a land-use strategy for the island (Safford 2001).
Create a protected area on Mt Karthala, extending below the native forest edge in the south, in order to encompass most of the known range of this species (Louette and Stevens 1992, Safford 2001). Consider reforestation of grasslands on the central ridge (Safford 2001). Develop an environmental education programme on the island (Louette and Stevens 1992). Encourage locally-organised ecotourism as an alternative source of income for inhabitants of the Mt Karthala area (Safford 2001).
