LC
Golden-backed Bishop Euplectes aureus



Justification

Justification of Red List Category
Although this species may have a restricted range, it is not believed to 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 common (Borrow and Demey 2001).).

Trend justification
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Distribution and population

This species is endemic to northern and central Angola, where it occurs along the coastal plain from Benguela and Cuanza Sul to Luanda, Bengo and southern Cuanza Norte, and inland along the Cuanza River to Dondo.

Ecology

This species occurs on floodplains and rank vegetation in savanna woodland on the coastal plain, and also in Acacia scrub and abandoned cotton fields (Traylor 1960). It may make small seasonal movements from wet to drier habitat.

Threats

Although the species has a relatively small range, suitable habitat (such as the flood plain of the Cuanza River and other low lying marshes in the area) is extensive and not easily impacted upon. However, during seasonal movements, it could be susceptible to habitat changes at the drier end of its range (Stattersfield et al. 1998, Dean 2001).
