「鳥」與「隹」都是由鳥的外形演變而來,衍生許多有此偏旁的鳥類漢字,於此簡單列舉常見鳥類漢字加註圖示說明。注意「鳥」是獨體漢字,而「隹」僅是部首,不單獨成字。
隹:雞、雀、雁
鳥:鴨、鵝、鴿、鴉、鷹、鷗、鶴
Both 「鳥」 and 「隹」 are from the shape of birds. There are many Chinese characters contain these two parts. Here I pick some common characters for example. Be aware that 「鳥」 is a Chinese character but 「隹」 is only a radical.
