Andaman Serpent-eagle Spilornis elgini

Justification
This species has a small, but not severely fragmented range, in which it is thought to be quite common, but may have a very small population with an unknown subpopulation structure. The forests of the interior of the Andaman Islands are coming under increasing pressure from agriculture and development schemes and this species is likely to decline concurrently. It therefore qualifies as Near Threatened.

Distribution and population
Spilornis elgini is endemic to South Andaman island, India, where it has been considered common (BirdLife International 2001).

Population justification
This species's population is preliminarily estimated to number 1,000-5,000 mature individuals, pending further research. This is roughly equivalent to 1,500-7,500 individuals in total.

Trend justification
There are no data on population trends; however; the species is suspected to be declining at a slow to moderate rate, owing to habitat degradation and hunting.

Ecology
The species occurs in the rainforests of the interior of the islands. It appears to be ecologically separated from Crested Serpent-eagle S. cheela, which inhabits coastal forests on the same island.

Threats
Although forest remains extensive on the Andamans, loss and fragmentation of cover continues and is perhaps accelerating. The human population on larger islands is rising rapidly and habitat is consequently under mounting pressure from agriculture, grazing and logging. Hunting is also apparently common on the islands and may affect this species.

Conservation Actions Underway
CITES Appendix II. Conservation Actions Proposed
Survey to assess the size of the population. Regularly monitor the population at selected sites across its range. Investigate its abundance in forest at different levels of perturbation. Protect significant areas of intact interior forest in the Andaman islands. Quantify the impact of hunting on populations. Conduct awareness campaigns involving local residents to engender pride in the species and prevent hunting.
