LC
Whiskered Flowerpecker Dicaeum proprium



Justification

Justification of Red List category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). Therefore, this species is now listed as Least Concern.

Population justification
The global population size has not been quantified, but the species is described as uncommon to locally common in forest edge and secondary growth above 900 m on Mindanao (Cheke et al. 2001).

Trend justification
The population is suspected to be in decline owing to ongoing habitat destruction.

Distribution and population

Dicaeum proprium is endemic to Mindanao, Philippines, where it is found at Mt Mayo, Mainit, Manticao, Misamis Oriental, Mt Kitanglad on the lower slopes of Mt Nangkabulos, Mt Piapayungan at Saronayan, Lumba-Bayabao, Mt Apo, Lake Sebu, Mt Matutum at Tupi, and Mt Sugarloaf at Burakan Hill. Although previously considered an uncommon, low-density species, and hence as threatened, recent evidence of its occurrence on Mt Kitanglad and on Mt Apo, Mindanao's two largest mountains, suggests that its overall numbers may be moderately high.

Ecology

It is found in primary forest, forest edge and second growth above 800-900 m.

Threats

Despite its ability to survive in second growth, and its absence from the lowlands, forest loss is assumed to have had some impact at the lower limit of its altitudinal range.

Conservation actions

Conservation Actions Underway
None are known.

Conservation Actions Proposed
Estimate net forest loss within its altitudinal range. Determine its population density, and use this to inform population estimates. Protect areas of suitable habitat.
