Trioceros johnstoni
Trioceros johnstoni is occupying montane and sub-montane forests at altitudes between 1,000 and 2,500 m (3,300–8,200 ft) in the Albertine Rift of eastern DRC, western Burundi, western Rwanda, and southwestern Uganda, but also tolerates agricultural and semi-urbanized areas, if trees remain present.
This species has a large distribution, of which 80% is estimated to consist of suitable habitat (IUCN Assessment).
However, its range is clustered into several isolated patches, the pertinent populations may represent separate forms/species:
RUWENZORI: form typical by red eyes in males
BWINDI: form typical by light blue eyes in males
RWANDA, BURUNDI: form typical by dark blue eyes in males
