I even warbled a Mae West type ditty. The male bird sings a series of warbled notes to defend his nesting territory. Males duet melodiously with a warbled "cheery cheery" answered by "cheery to you". These birds have a flute-like warbled song. Their call is a thin 'few'; while their song is warbled high 'chur chur'. Its call is "chissick" or "cheree", and the song is a warbled "zee-zeree-chereeo". Its song is a warbled "zee-zeree-chereeo".
