戴菊Regulusregulus，探索奇妙的鸟类

雀形目，戴菊科

体长：9～10厘米；体重：5～4克

戴菊喜欢在海拔1 500～2 500米的山地森林中生活，常集成小群在针叶树上活动，为树木清除各种寄生虫。它们个头小，又喜欢在树丛中不断飞跃穿插，想要观赏、拍摄它们十分不易。在兴奋或紧张时，戴菊会张开额头的菊黄色羽冠，那是它们最漂亮的时候。

Small but lively,Regulus regulus tends to live in groups in montane forests at an altitude of 1.5 to 2.5 kilometers.Coniferous trees are its favorite habitats.Regulus regulus is characterized by its chrysanthemum yellow crest,which spreads when it feels excited and nervous.
