LC
Buff-banded Rail Hypotaenidia philippensis



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 <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 trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, 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). For these reasons the species is evaluated as Least Concern.

Trend justification
The overall population trend is stable, although some populations have unknown trends (Wetlands International 2006).

Distribution and population

Hypotaenidia philippensis has a distribution spanning much of Indomalaya, Australasia and Oceania. It occurs in the Cocos (Keeling) Islands (to Australia), the Philippines, Indonesia, Palau, Papua New Guinea, the Solomon Islands, Australia, Norfolk Island (to Australia), New Zealand, New Caledonia (to France), Vanuatu, Fiji, Tonga, Samoa and Niue (to New Zealand) (del Hoyo et al. 1996). The subspecies macquariensis, of Australia's Macquarie Island, went extinct in the late 1800s (Hamilton 1894).
