LC
Southern Brown-throated Weaver Ploceus xanthopterus



Justification

Justification of Red List Category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but the species is described as uncommon in much of its range (Fry and Keith 2004).

Trend justification
The population is suspected to be in decline owing to disturbance of its wetland habitat in south Mozambique and Botswana (Fry and Keith 2004). There have been no recent records from some areas where it was previously recorded, however there do not appear to have been significant declines in least Malawi or Zambia ( F. Dowsett-Lemaire and R. Dowsett in litt. 2005, P. Leonard in litt. 2005, S. K. K. Olofson in litt. 2005).

Distribution and population

This species is endemic to south and east Africa, where it occurs in South Africa, Namibia, Botswana, Mozambique, Zimbabwe, Zambia, Malawi, Tanzania and the Democratic Republic of Congo.

Ecology

This is a social species which breeds in papyrus, reedbeds and shrubbery overhanging water, at around 1,750 m elevation (van Perlo 1995). Colonies of up to 300 nests have been found in areas of suitable habitat.

Threats

Disturbance of its wetland habitat threatens the species in south Mozambique and Botswana (Fry and Keith 2004).
