These questions are important to us if we are to enjoy the presence of sunbirds and other nectarivorous birds in our gardens. But the questions are far more important to plants, because nectar-feeding birds pollinate specific plants, enabling them to produce seeds. This mutual relationship fosters plants dependent on the birds, while the birds in turn rely on the plants for food.

As cities grow, they tend to crowd out natural areas, and residential areas are often avoided by birds. If the development of towns and cities means that nectar bearing plants and nectar-feeding birds become isolated in small fragments of natural habitat, both birds and plants will suffer. However, urban areas with gardens can be made less hostile and some brave or adaptable birds will enter and use these new habitats.

Urban environments that allow nectar feeding birds to move between fragments of natural habitats are especially important in the Western Cape, for two reasons. Firstly, Cape Town and the greater Boland suburbs are in
