Standardwing Semioptera wallacii

Justification
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.

Taxonomic source(s)
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.

Distribution and population
Semioptera wallacii is found on Halmahera, Kasiruta and Bacan, Indonesia (del Hoyo et al. 2009).

Population justification
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).

Trend justification
The population is suspected to be in decline owing to on-going habitat loss (Frith and Beehler 1998). A recent study by Vetter (2009) used remote sensing techniques to track the rate and spatial pattern of forest loss in the Northern Maluku Endemic Bird Area between 1990 and 2003, and project rates of deforestation over the next three generations for restricted range bird species found in this region. This study estimated the rate of forest loss within the geographic and elevation range of Standardwing to be c.8.4% between 1990 and 2003, and projected the loss of c.16.6% of forest in its range over the next three generations (estimated by BirdLife to be c.24 years, based on an estimated generation length of c.7.9 years) (Vetter 2009).

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).

Threats

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.
