LC
Common Bulbul Pycnonotus barbatus



Justification

Justification of Red List Category
This species has an extremely 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 increasing, 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 to abundant. The population in Liberia is estimated as 3 million individuals and In southern Mozambique, the population is estimated as 5-10 million individuals. However, these countries cover only a small percentage of the species's total range so the global population is likely much higher (del Hoyo et al. 2005).

Trend justification
The population is suspected to be increasing owing to ongoing habitat modification and degradation, which favours the species (del Hoyo et al. 2005).
