Yellow-streaked Greenbul Phyllastrephus flavostriatus


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 common to locally abundant (del Hoyo et al. 2005).

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 has a large, discontinuous range in East Africa. Race alfredi, sometimes considered a separate species, is a restricted-range taxon and is found in the Tanzania-Malawi Mountains EBA. The species is present in numerous forest reserves and other protected areas (Fishpool and Tobias 2005).


The species occupies lowland, mid-altitude and montane forest, riverine forest, thick bush and bamboo thickets from sea-level to 3000 m, where it feeds primarily on arthropods but also on fruit, usually foraging in the middle and upper strata. A noisy and conspicuous bird, it is often seen in small groups and mixed-species flocks (Fishpool and Tobias 2005).
