Lina's Sunbird Aethopyga linaraborae



Justification

Justification of Red List category
This species occupies an extremely small range, but as it occurs in montane forest within this, it appears to be relatively secure at present and is therefore classified as Near Threatened. Careful monitoring of potential threats is needed.

Population justification
The global population size has not been quantified, but the species is described as fairly common within its very small total range (Cheke et al. 2001).

Trend justification
The population is likely to be stable given the rugged and inaccessible mountains within its range, as it is generally too steep for agriculture. Habitat degradation due to mining may affect the population in some parts of its range (Mohagan et al. 2015), although the extent to which this may cause burden needs further monitoring.

Distribution and population

Aethopyga linaraborae is endemic to Mindanao, Philippines, where it is currently known from Mts Mayo, Puting Bato (Tagub) and Pasian in the eastern provinces of Davao del Norte and Davao Oriental. However, it has also been recorded in the lower montane forest of Mt. Hamiguitan at an elevation of 1,000-1,100 m (Mohagan et al. 2015). It is relatively common in suitable habitat within its altitudinal range; assuming that it generally occurs in all available remaining habitat above 1,000 m, its total range likely comprises c. 1,200 km2, but it is unlikely to be seriously threatened in the present or near future.

Ecology

It occupies montane mossy forest from 970-2,000 m and above. Breeding appears to take place in May, but may happen at other times of year.

Threats

As it occurs in rugged and inaccessible mountains that contain few commercial tree species and generally are too steep for agriculture, it is unlikely to face significant threats at present. However, habitat destruction by mining activity may be prevalent near Mt. Hamiguitan (Mohagan et al. 2015). 

Conservation actions

Conservation Actions Underway
None are known.

Conservation Actions Proposed
Monitor potential threats within its altitudinal range. Grant protection to areas of suitable habitat to safeguard against future threats. Monitor important areas (such as area surrounding Mt. Hamiguitan) regularly to strengthen conservation action (Mohagan et al. 2015).
