Geographic Range [top]

Range Description:

Xenocopsychus ansorgei has a localised distribution on the escarpment of western Angola, where it is confined to four areas, eastern Namibe and Huila, N'Dalatando in Cuanza Norte, Mt Soque in Huambo and the Gabela area in Cuanza Sul (Dean 2000). In May 2012, three pairs were recorded in the Zebra Mountains of northern Namibia, c.240 km south of the closest previously-known population in Angola, with birds since recorded at other nearby sites with suitable scree slopes (Swanepoel 2013). It is common where it occurs.

♦ Continuing decline in subpopulations:	Unknown
♦ Extreme fluctuations in subpopulations:	No	♦ All individuals in one subpopulation:	No
♦ No. of individuals in largest subpopulation:	100

Habitat and Ecology [top]

Habitat and Ecology:	The species is present at 690-2,200 m (del Hoyo et al. 2005). It is found in caves and on rocky grassland slopes and cliffs with nearby forest, feeding on insects. The species is reportedly also seen in riverine forest and thick undergrowth on forested slopes (del Hoyo et al. 2005). It forages on or near the ground. Breeding takes place in September-November, with pairs producing two broods in rapid succession. The nest, in which 2-3 eggs are laid, is an open cup of twigs, grasses and dead leaves, lined with plant material, and situated on a rock ledge under an overhang (del Hoyo et al. 2005).
Systems:	Terrestrial
Continuing decline in area, extent and/or quality of habitat:	Unknown
Generation Length (years):	3.8
Movement patterns:	Not a Migrant

Threats [top]

Major Threat(s):	This species's fairly limited range may make it vulnerable to alterations to its habitat. This would probably be most likely driven by the spread of small-scale cultivation and livestock farming.
