| 2009 IUCN Red List Category (as evaluated by BirdLife International - the official Red List Authority for birds for IUCN): Least Concern Justification 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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to 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. Family/Sub-family Psittacidae Species name author (Gmelin, 1788) Taxonomic source(s) Dowsett and Forbes-Watson (1993), Sibley and Monroe (1990, 1993) Taxonomic note Poicephalus robustus (Sibley and Monroe 1990, 1993) was split into P. robustus and P. fuscicollis by Perrin (2005) and Wirminghaus et al. (2002), in the latest of a series of attempts to justify species status for P. robustus robustus, but nothing in this recent review supplies new or at least clear evidence either of the parapatry of the forms robustus and suahelicus or of their use of different habitat (the suite of habitats used by suahelicus is inadequately covered). Therefore this split is not accepted until better evidence is provided.
