The greater double-collared sunbird (Cinnyris afer, Linnaeus 1766) is a 14 cm passerine in the family Nectariniidae, resident in southern, eastern and northeastern South Africa, Eswatini, and eastern Lesotho. The adult male is unmistakable: iridescent metallic green on the head, throat and back with a broad scarlet breast band separated from the green by a narrow metallic blue border. It feeds primarily on nectar, probing tubular and cup-shaped flowers across fynbos, forest edges, montane shrublands and gardens; it supplements its diet with fruit and, especially when raising young, insects and spiders. As a regular visitor to bird-pollinated genera including Aloe, Erythrina, Tecoma and Leonotis, it functions as an incidental pollen vector across its range and is a highly garden-attractable species wherever nectar-rich Southern African natives are grown.
