It breeds in coniferous forests of Siberia and winters mainly in India. The song of the Siberian Chiffchaff only vaguely resembles that of the Common Chiffchaff. It is much softer, less regular, but more melodic, and can be likened to the song of the Willow Warbler. Its calls are thin and monosyllabic, rather like a Eurasian Bullfinch call."}
