Taiwan is located in the subtropics. It has high rainfall and high humidity. The Central Mountain Range bisects the island north to south. Its peaks, including many high ones, run in an unbroken chain. The island is home to an abundant variety of fauna and flora. Over 60 percent of the island's wild animals live at medium to high elevations. There are 27 different species of diurnal birds of prey in Taiwan, all of which belong to the order Falconiformes. They are big and strong with short, broad beaks that are shaped like hooks. Their claws are sharp and they are very good flyers. Mainly, they feed on other animals. The impression they give people is of fierceness and grandeur. At the top of the food chain, they require large habitats. Once their habitat becomes polluted or too small, or their prey becomes scarce, their numbers decline or they even disappear from an area. This is an issue deserving everyone's attention. Conservation efforts need to be bolstered. To make a general appeal for people to cherish our natural ecological resources,this Directorate has specially chosen four endangered diurnal birds of prey that are currently the target of conservation efforts as the subject matter for a set of eight stamps. The four native birds that have been chosen are (1) Spizaetus nipalensis the Hodgson's Hawk Eagle; (2) Spliornis cheela the Crested Serpent Eagle; (3) lctinaetus rnalayensis, the Indian Black Eagle and (4) Milvus migrans, the Black Kite. Four of the stamps will have face values of NT$5.00 and the other four face values of NT$10.00. The stamps are printed in horizontalse-tenant pairs, each pair consists of one stamp with the subject bird in flight and another stamp of the bird standing still, with a continuous vista of background scenery running across the pair from stamp to stamp. Professor Li Ling-linq of the Zoology Department of National Taiwan University served as planning consultant for these stamps.
