Fork Tailed Drongo (Dicrurus adsimilis) Displaying His Forked Tail


The fork-tailed Drongo, also called the common Drongo, African Drongo, or savanna Drongo is a type of small passerine bird of the Old World tropics. The fork-tailed Drongo is a common and widespread resident breeder in Africa south of the Sahara. These insect-eating birds are usually found in open forests or bush. Two to four eggs are laid in a cup nest in a fork high in a tree. These are aggressive and fearless birds, given their small size, and will attack much larger species, including birds of prey if their nest or young are threatened. The male is mainly glossy black, although the wings are duller. It is large-headed and has the forked tail, which gives the species its name. The female is similar but less glossy. It is fairly easily distinguished from other black birds by its red eye. It is also very easy to see, as its habit of hawking insects from open perches means that it is conspicuous. Although normally a diurnal bird, there have been examples of Drongos taking advantage of the artificial lighting to take moths late into the evening. The fork-tailed Drongo has short legs and sits very upright whilst perched prominently, like a shrike. The bill is black and heavy. It flycatches or takes prey from the ground and is attracted to bush fires. Observations show that the fork-tailed Drongo in Africa are capable of using deceptive mimicked alarm calls to steal food from birds like pied babblers and animals such as meerkats. Sometimes when a predator is approaching, Drongos act as sentries and warn their neighbours with genuine alarm calls, but Drongos also earn quarter of their daily calories by sounding a false alarm, when the other animal finds food. When the meerkats and babblers flee from the non-existent predator, the Drongo steals their food. Researchers have considered the possibility that Drongos possess theory of mind, not fully shown in any animal other than humans, but there are still significant doubts about this capability.
