LC
Philippine Green-pigeon Treron axillaris



Justification

Justification of Red List category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 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). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). 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 (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.

Population justification
This species is considered to have a high dependency on forest habitat, and tree cover is estimated to have declined by 6.7% within its mapped range over the past three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). It is therefore tentatively suspected that this rate of cover loss may have led to a decline of between 1-19% in the species' population size over the same time frame, with a best estimate of reduction being 5-9%.

Trend justification

Distribution and population

The population is suspected to be in decline owing to high hunting pressure, and it is now uncommon or rare in parts of the range (Gibbs et al. 2001).

Ecology

Occurs in lowland evergreen forest (Gibbs et al. 2001). Breeding behaviour has been reported in May and June (Gibbs et al. 2001).

Identification

c. 28 cm. A medium-sized green pigeon with a grey crown (whitish forecrown), bright yellow fringes to wing coverts and flight feathers, blue-grey legs and a red base to the bill. Male has a maroon back, in the female this is green. Similar spp. T. aromatica lacks the red base to the bill, has a smaller and much darker maroon area on the back and has a more clear cut, larger and bluer crown patch extending further onto nape. T. phayrei lacks the red base to the beak, and also has an orange-yellow breast patch and pinkish red feet. T. affinis also lacks the red base to the bill. Thick-billed Pigeon T. curvirostrata has red legs and feet, bare skin around the eye and has rufous undertail coverts.
