The white-browed coucal (Centropus superciliosus) is a species of cuckoo in the Cuculidae family. It is found in sub-Saharan Africa. It inhabits areas with thick cover afforded by rank undergrowth and scrub, including in suitable coastalregions.
The southern subspecies is sometimes split as Burchell’s coucal, Centropus burchelli. According to popular Southern African lore, this species’ distinctive call, which resembles water pouring from a bottle, is said to signal impending rainfall, earning the bird the affectionate moniker rainbird. source
