|Scientific Name:||Semioptera wallacii|
|Species Authority:||Gould, 1859|
|Red List Category & Criteria:||Near Threatened ver 3.1|
|Facilitator/Compiler(s):||Butchart, S., Ekstrom, J., Symes, A. & Taylor, J.|
This species appears to rely on primary forest, and has been uplisted to Near Threatened following recent information on forest loss in its small range, in which suitable habitat is declining and may already be very fragmented. On-going forest loss is inferred to be driving continued declines in its population.
|Range Description:||Semioptera wallacii is found on Halmahera, Kasiruta and Bacan, Indonesia (del Hoyo et al. 2009).|

|Population:||The global population size has not been quantified, but the species is reported to be generally common on Halmahera and Bacan (Frith and Beehler 1998).|
|Habitat and Ecology:||This species inhabits primary, secondary and logged rainforest in the lowlands and hills, from sea-level to 1,000-1,200 m, but mostly above 250 m, occurring rarely in mature secondary woodland (del Hoyo et al. 2009, Burung Indonesia in litt. 2014). Although it occurs in secondary forest, lek sites have only been found in primary forest (Burung Indonesia in litt. 2014).|
The primary threat to the species is habitat loss through commercial logging for timber, and clearance for shifting agriculture, mining, settlements and plantations of oil palm, coffee, rubber and timber species (Vetter 2009, Burung Indonesia in litt. 2014). Another potential threat is posed by wildfires, which have devastated areas on other Indonesian islands, with the chances of such fires being increased by the conversion of forest to scrub and grassland and the opening up of forests for road construction, as well as selective logging and fragmentation (Vetter 2009).
Conservation Actions Underway
The species occurs in Aketajawe Lolobata National Park (Halmahera) (Burung Indonesia in litt. 2014).
Conservation Actions Proposed
Carry out surveys to assess the species's population size. Conduct regular surveys to monitor the population trend. Track rates of habitat loss through regular studies of satellite images. Increase the area of suitable habitat with protected status.
