To test the idea systematically, Bruce Anderson of the University of KwaZulu-Natal in Pietermaritzburg, South Africa, and his colleagues closely monitored flowers in the wild, leaving some of them as they were and removing the perches from others. The only pollinator seemed to be the malachite sunbird (Nectarinia famosa).
