It feeds on insects and other invertebrates. The nest is a cylindrical cup of reed stems and leaves lined with finer material. The breeding season is from May to July; the 3-6 eggs are incubated for 13 or 14 days by the female alone.
In Egypt, it is a common resident breeder in the Nile Valley and Delta.
