Geographic Range [top]

Range Description:Sylvietta philippae is found in north-west and west Somalia and adjacent parts of Ethiopia (Urban et al. 1997) up to 80 km from the border (L. D. C. Fishpool in litt. 2006), but may be more widespread in Ethiopia (Ash 1982). There are also several records in the Bogol Manyo area in south-east Somalia (J. Ash in litt. 2007), and recent records from near Inaafmadow in north-west Somalia (Mills and Cohen 2015). In Somalia it has been described as widespread but not particularly common, and given the size of its range it may not be at risk (J. Miskell in litt. 2006).

Population [top]

Population:The global population size has not been quantified, but the species is described as fairly common (del Hoyo et al. 2006).

Trend Justification:  The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
Current Population Trend:Stable

Number of mature individuals:UnknownContinuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No
No. of individuals in largest subpopulation:100

Habitat and Ecology [top]

Habitat and Ecology:It is a bird of semi-desert, frequenting fairly dense thickets of Acacia and Commiphora on rocky ground and red sandy soil, where it feeds on minute beetles and other insects (Urban et al. 1997). It has been noted as fairly common at about 300 m elevation, and ranges up to 900 m (Urban et al. 1997).

Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):5
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): At one site in Ethiopia the species is possibly threatened by exploitation of its scrub habitat for charcoal production and extraction of gum and resin (EWNHS 1996). As it appears to be restricted to denser areas of thicket it could be sensitive to habitat alteration through fuelwood collection or grazing.
