NECTAR IN THE GARDEN
Like the hummingbirds of the Americas, Africa’s sunbirds and sugarbirds are specialised nectarivores (feeding primarily on nectar produced by flowers), but supplement their diet with some protein by eating small insects, especially when feeding their chicks. Both sunbirds and sugarbirds are incredibly well adapted to collect the energy-rich nectar from flowers and in doing so, usually pollinate the obliging flower. However, sunbirds and sugarbirds have developed slightly different ways to collect the nectar. Both sunbirds and sugarbirds have long, thin bills that enable them to reach deeply into a trumpet-shaped flower to get to the sweet nectar right at the back of the flower. Their tongues are even longer than their bills, and in the case of sunbirds, the sides of their tongue roll up to form a tube through which the nectar can be sucked up using capillary action. A sugarbird’s tongue, however, has a fine brush on the tip used to lap up the nectar.
Many flowers make use of these birds as sole pollinators, enticing them with the reward of nectar. In the process pollen is dabbed on the bird’s forehead. When the bird drinks nectar from the next flower, the pollen is brushed off onto the flower’s stigma and the flower is pollinated. Both types of birds are especially fond of the colours red, orange and dark pink, and therefore most bird-pollinated flowers are red in colour.
There are at least six different species of sunbird as well as the iconic Cape Sugarbird in the Garden Route. The sunbirds, in particularly the males, are usually superbly colourful with iridescent blue, green, red and purple feathers. Attract some of these gorgeous birds to your garden by planting the nectar-providing flowers that supply them with the energy they need for survival. This list of indigenous plants (bulbs, succulents, shrubs and trees) will provide nectar-rich flowers to attract sunbirds and sugarbirds to your garden.
