The grey-backed camaroptera is vocal, and gets its alternate common name, the bleating warbler, from its very loud alarm call which sounds like the bleating of a lamb. They also make another loud call that sounds like two stones being banged together. These birds skulk around in dense brush and are often heard, seldom seen. The grey-backed camaroptera binds large leaves together low in a bush and builds a grass nest within the leaves. The normal clutch is two or three eggs.
