The Rattling Cisticola occurs in savannas, especially those dominated by thorny trees and bushes, and woodland. It feeds mainly on insects and other invertebrates, but have also been observed taking nectar from aloes.
Rattling Cisticolas are usually seen in monogamous pairs or family groups, and breed in spring and summer. They construct ball-shaped nests near the ground in a shrub or tuft of grass. The female takes sole responsibility for incubating the clutch of 2-5 eggs for 2 weeks, with the chicks leaving the nest about the same length of time after hatching. Adults are approximately 15cm long and weigh around 16g.
According to the IUCN the Rattling Cisticola is of least concern, and it occurs from Ethiopia southwards. In South Africa it is commonly found through most of Kwazulu-Natal, in Mpumalanga, Limpopo, Gauteng, North West, the eastern reaches of the Northern Cape and the north-western parts of the Free State, often being one of the most numerous bird species where they’re found.
