LC
Principe Seedeater Crithagra rufobrunnea



Justification

Justification of Red List Category
Although this species may have a small 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 race thomensis is described as common and the nominate race is described as scarcer than thomensis (Clement et al. 1999).

Trend justification
Some survey work has suggested that it may prefer primary forest (see Dallimer et al. 2012). However, it may also occur in a range of degraded habitats such as plantations, edge habitats and even in city gardens (Clement 2018). Therefore, the population is tentatively suspected to be stable in the absence of evidence for any declines or substantial threats.
