United Nations declared 2011 the International Year of Forests. To coincide with this, the South African Post Office chose forest birds as its theme for a new set of stamps in the South African bird series.In South Africa, indigenous forests cover only about 0,25 percent of South Africa\’s land surface. With a few exceptions, such as the forests of the Knysna area and the KwaZulu-Natal coastal dune systems, forests are small, usually occupying less than 1 000 ha. These forests provide shelter to some of South Africa\’s most spectacular birds.The birds depicted on the set of five stamps are the green twinspot, olive bush-shrike, Cape parrot, Knysna turaco (lourie) and the African crowned eagle. The artwork is by Andre Olwage.
