Han character 𪄮

𪄮 is a variant of 雇, a name for birds said to signal when to farm and raise silkworms. The Han-era Shuowen Jiezi, an early Chinese character dictionary, gives this bird-name explanation; 雇 also appears in oracle-bone inscriptions. The Zuo Zhuan, a chronicle of the Spring and Autumn period, describes nine bird-named farming officials. Dictionaries also list 𪄮 as a variant of 顧, “look back,” so context decides the reading.
