唐人一改六朝以來以詠物角度把鶴寫入詩中的方式，而以更真實、白描的創作態度觀鶴、寫鶴，白居易更是唐代詩人最值得注意者。在白居易詩中，鶴是最常出現、意義最為複雜的鳥類形象。總的說來，白居易筆下的鶴，不再專注歌詠鶴之神態形儀之美，而賦予更豐富更複雜的形象與寄託。其一，他雖延續六朝以來的意象傳統，但表達的是個人在仕隱衝突過程中的不自由感和內慚感。其二，鶴不僅與白居易的晚年生命有密切聯繫，更成為他日常生活的陪伴者和觀照自我年齡身體的對象。這個特色的形成當然與東都洛陽的養鶴風氣有關，但更值得注意的是白居易以一種親切、無隔的情感態度來觀鶴。其三，鶴乃是白居易晚年在園林中進行遊戲性詩歌創作的主角，但這種遊戲又與詩人本身的處世態度和政治感懷有關。惟有透過這三類鶴形象的把握，才能展現白居易詠鶴的獨創性，瞭解其是以鶴來作為個人生命歷程的真實映現。
