Togian White-eye Zosterops somadikartai

Justification
This newly described species has a very small range in which habitat degradation is likely to be causing the population to decline. However, it is not known to be severely fragmented or restricted to few locations, therefore the species is classified as Near Threatened. Further information may lead to the species being uplisted in the future.

Taxonomic note
Zosterops somadikartai was described as new to science by Indrawan et al. (2008).

Identification
c. 11 cm. Forehand and forecrown (to above eye) and lores black. Dark, slaty grey, bare, fleshy eyering with some tiny white white feathers visible at extremely close range. Upperparts from rear crown to back citrine. More olive on side of head, rump yellow-tinged olive-green. Upperwing-coverts olive-green, flight-feathers and tail feathers with yellowish olive-green edges and blackish tips. Chin and throat sulphur-yellow, upper breast pale grey, lower breast and bell white. White underwing-coverts. Iris dark red, bill black, pale flesh at base of lower mandible. Legs metallic horn. Voice Thin sweet warble, similar to that of Z. atrifrons but less modulated. Twittering chirrups heard from small moving flocks.

Distribution and population
Zosterops somadikartai is native to the Togian Islands, Indonesia. Its population size has not been quantified owing to its recent discovery, but is has been described as uncommon and localised, and the population is suspected to be declining owing to habitat destruction (del Hoyo et al. 2008, Indrawan et al. 2008).

Population justification
The population size of this species has not been quantified but is has been described as uncommon and localised.

Trend justification
Population trends are not available for this species owing to its recent discovery, however the population is suspected to be declining owing to ongoing habitat loss (Indrawan et al. 2008).

Ecology
This species has been recorded in low bushes near mangroves, gardens, coconut groves, secondary shrub, and in logged-over forest from sea level to 100 m (del Hoyo et al. 2008, Indrawan et al. 2008, D. Indrawan in litt. 2010). It typically roosts in shrubs which are 5-15 m tall. Its diet is comprised of insects, including caterpillars, which are gleaned from branches and beneath leaves. It forages in pairs or small flocks of up to five individuals, often visiting dense, low shrubs (del Hoyo et al. 2008, Indrawan et al. 2008).

Threats
The extent and quality of suitable habitat on the Togian Islands is likely to be decreasing owing to conversion and overexploitation of resources (del Hoyo et al. 2008, Indrawan et al. 2008).

Conservation Actions Underway
The Togian Islands have been declared a national park (del Hoyo et al. 2008). Conservation Actions Proposed
Assess the population size and establish a monitoring programme to establish trends. Establish ecological requirements. Identify and assess threats.
