Common resident birds, an endemic subspecies of Taiwan, 29-30 cm in length. Males and females share the same body color and are similar in size. It has a long and deeply forked tail, which curves out at the end, giving it its Chinese name. An allied species, the Bronzed Drongo, can be found in medium and low altitude mountains. It is often seen singly or in small groups, perching on branches or along power or telephone lines. The flight of the Black Drongo resembles the rising and falling of the waves on the sea, giving a sense of beauty and elegance. While in flight, it can slow down and switch directions swiftly. It breeds between April and July, building cup-like nests among branches or in telephone poles. During the breeding season, Black Drongos are highly territorial and would attack people or animals that come near their nests, including birds of prey. (Photo courtesy of Lu Wei-yuan)
