Fork-tailed Drongo

Dicrurus adsimilis

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The fork-tailed drongo is a glossy black bird with red eyes and a deeply forked tail, very common in the African savannahs. It catches insects in flight from a perch and is notably aggressive: it mobs raptors far larger than itself. Its most celebrated behaviour is a form of deliberate deception that has become a classic case study in animal cognition.

Fun facts

  • It lies to steal food: it gives false predator alarms, including imitations of the alarm calls of meerkats and of other birds, so that they abandon their prey and it can take it.
  • It switches strategies to keep the deception working: if one kind of false alarm stops having an effect, it changes to another species' call, which shows that it adjusts its tactics to the victim's response.
  • Most of the time, however, its alarms are genuine, and the meerkats and other animals heed them precisely because the drongo is reliable eighty per cent of the time.
