Fork-tailed Drongo

Common resident. Differs from all similar black birds in prominent forked tail, the outer feathers splayed outwards; cf. [Common Square-tailed Drongo], which has only a shallow fork in its tail. Other features are deep ruby-red eye and powerful bill. Sexes alike; immature as illustrated. Utters a variety of unmusical twanging notes interspersed with imitations of other bird calls, especially those of owls and other birds of prey. Occurs singly or in pairs in almost any non-forest habitat with trees. Noisy and aggressive.
