Stuhlmann's Sunbird

The Rwenzori double-collared sunbird, also called Stuhlmann's sunbird or the Rwanda double-collared sunbird, is a species of bird in the family Nectariniidae. It is found in the Ruwenzori range of mountains in south central Africa. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. It is sometimes considered to be a subspecies of the greater double-collared sunbird. Some authors consider this bird to be part of a species complex with Cinnyris afer, where it joins Ludwig's double-collared sunbird and Prigogine's double-collared sunbird. As with other closely related species, each inhabiting different locations, there are subtle similarities and differences between the local populations, and their taxonomic treatment depends on the views of the taxonomist.
