The flag rongo ( Dicrurus paradiseus ) is a Southeast Asian songbird.
features
Of the 63 cm of the body length alone, 35 cm are accounted for by the long, forked tail, the elongated outer feathers of which have a long, wire-like quill with a broad flag at the end, the flag . The dark plumage shimmers blue-green. Another characteristic is the loose, backward-curved hood.
The call of the flag drongo sounds metallic, the song contains melodic, whistling tones, as well as imitations of other birds.
The on Sri Lanka living subspecies Dicrurus p. ceylonicus lacks the elongated tail feathers.
Occurrence
The distribution area of the flag trongo extends from India eastward over the Himalayas to southern China and southward to the islands of Borneo , Java and Bali . It lives mainly in rainforests and bamboo forests.
behavior
The flag rongo feeds primarily on insects. He looks for them in the foliage or catches them in flight. He often joins groups with other insect-hunting birds in order to scare away insects from the vegetation together and to be able to capture them more easily. The flag rongo is considered to be aggressive and fearless and also attacks larger birds when they threaten its brood.
On the Nicobar Islands, flag drongos cooperate with hawks and Nicobar shrews in foraging.
Reproduction
The bowl-shaped nest is built in the fork of a high tree made of plant material and glued with cobwebs. The clutch consists of three to four eggs.
