||43 cm. Large, green bird, dark green to paler green on the underparts with diagnostic (within its range) orange crest. In flight, shows bright crimson wing-patches. Juvenile a duller version of adult. Voice Typical kow kow kow of green turacos but higher-pitched and more rapid delivery. Song readily distinguished from Green Turaco T. persa by spacing between first note and rest of song. Hints Very secretive and difficult to see but has loud, distinctive call which can be heard for up to 1 km in hilly areas. Singing most frequent during the breeding season.

This species is listed as Endangered because it has a very small range, which is severely fragmented and suffering a continuing decline owing to pressure from human use on its montane forest habitat.

|Range Description:||Tauraco bannermani is mainly restricted to the Bamenda Highlands in western Cameroon, but small populations exist on nearby Mt Mbam (Njabo and Languy 2000) and, most recently discovered, at Fossimondi and Fomenji to the south-west (Nkembi et al. 2006). It is only likely to survive if the Kilum-Ijim forest, the largest remaining montane forest area in the Bamenda Highlands, is preserved (D. Thomas in litt. 1996). Research in 1994-1995 found the species in several remaining forest remnants in the Bamenda Highlands and seemingly able to survive in very small forest fragments (<1 km2) (McKay and Coulthard 1996). However, follow-up surveys in 2000 found some of these forest fragments had almost completely disappeared, with T. bannermani either absent or with only a few pairs remaining (Njabo and Languy 2000). In Kilum-Ijim, it is unlikely that more than 1,000-1,500 pairs occur (Forboseh and Ikfuingei 2001). In 2003-2009 it was regularly seen/heard in Mendongbuo (Big Babanki) and adjacent montane areas, recorded at 9 out of 23 forest counting points (Reif et al. 2006, Sedláček et al. 2007, Hořák et al. 2010).|

|Population:||The total population is estimated in the range 2,500-9,999 individuals based on data given by Forboseh and Ikfuingei (2001). This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.|
Trend Justification: This species's population is suspected to be decreasing rapidly, in line with habitat loss and degradation within its range.
