The White-browed Coucal (Centropus superciliosus) is a medium-sized bird, 14" (41cm), which is shy and secretive, calling from thick cover. Due to its call, many safari guides call this 'the water-bottle bird', because of its bubbling "woo-woo-woo-woo" notes, that fall, before rising with a stammer at the end.
The White-browed Coucal is often found in bushed or wooded grasslands, or lakeside thickets. It is closely related to the Cuckoo, although it is not parasitic and raises its own young, making grassy, domed nests in tall grass or thick vegitation. The Coucal is good at relationships and pairs for life. If one bird dies, the other spends days in mourning.
They are not good fliers, possibly due to their bulk, so they rarely wander from their territory. Although they appear ungainly, Coucals spend much of their time walking stealthily through vegetation, in search of food - which includes insects, as well as eggs, baby birds, reptiles and amphibians.
