Schouteden's Swift Schoutedenapus schoutedeni

Justification
This little-known species is presumed to have a small population which is almost certainly declining as its forest habitat is severely threatened. It is, therefore, classified as Vulnerable.

Identification
17 cm. Dark-coloured swift. Appears all black in the field with medium-forked tail. Similar spp. May be impossible to separate in the field from Scarce Swift S.myoptilus. Voice Unknown.

Distribution and population
Schoutedenapus schoutedeni is known with certainty from only five specimens to the east and north-east of the Itombwe Mountains in the eastern Democratic Republic of Congo (DRC), where it appears to be resident. However, there are possible sightings from Bwindi Forest, Uganda (near the border with the DRC), and from Mt Tshiaberimu to the north-west of Lake Edward (DRC) (Sarmiento and Butynski 1997), which indicates that the species may have a less restricted range than previously thought (T. Butynski in litt. 1999).

Population justification
The population is assumed to be small (<10,000) owing to the lack of confirmed records other than five specimens collected during 1956-1972. It is placed in the band 2,500-9,999 individuals, equating to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification
The population is suspected to be declining in line with the clearance and degradation of forest within the species's range.

Ecology
Until recently, the species was known only from clearings in transitional and lowland forest, at low and intermediate altitudes (c.1,000-1,470 m), but there are now indications that it may also be found over montane forest (up to 2,700 m; T. Butynski in litt. 1999). Breeding takes place in February or March.

Threats
Habitat loss is the most likely threat as the Itombwe Forest is under increasing pressure from pastoralists, farmers, pit-sawyers, miners and hunters (Omari et al 1999), although this may be reduced by its recent designation as a community reserve (A. Plumptre in litt. 2007). Clearance for agriculture has increased dramatically in the past few years as corn crops have failed, causing famine (Omari et al 1999). The human population in the area is increasing rapidly, and thousands of refugees from Burundi and Rwanda live in camps at the base of Itombwe's eastern escarpment and to the north (Omari et al 1999).

Conservation Actions Underway
Itombwe Forest has recently been gazetted as a community reserve, although the boundaries still need to be defined (A. Plumptre in litt. 2007). No other potentially relevant conservation action is known. Conservation Actions Proposed
Conduct field surveys in the Itombwe Mountains to determine its distribution more accurately and to assess its population size. Once a baseline population estimate has been obtained, continue to monitor population trends. Monitor rates of habitat loss and degradation within the species's range. Ensure effective protection of Itombwe Forest Community Reserve. Increase the area of suitable habitat that has protected status.
