Dicruridae – Drongos
The drongos, Dicruridae, are a family of passerine birds of the Old World tropics. They are related to the Rhipidurinae (Australasian fantails), Monarchinae (monarchs and paradise flycatchers) and Grallininae (magpie-larks).
Drongos are mostly black or dark grey, short-legged birds, with an upright stance when perched. They have forked tails and some have elaborate tail decorations. They feed on insects which they catch in flight. Several species of animals and birds respond to drongos’ alarm calls, which often warn of the presence of a predator. They have been shown to utter hoax alarm calls in order to benefit from the false alarms as other birds scatter leaving them to the food source. (Fork-tailed or common drongos in the Kalahari desert are known to use alarm calls in the absence of a predator to cause animals to flee and abandon food, which they eat, getting up to 23% of their food this way.)
These insectivorous birds are usually found in open forests or bush. They sit very upright whilst perched, like a shrike.
Two to four eggs are laid in a nest high in a tree. Despite their small size, they are aggressive and fearless, and will attack much larger species if their nest or young are threatened.
