Zi Collection, Upper Volume Radical: Bird (niǎo) Page 701, Entry 08 Pronounced hū (rising tone) Refers to a type of bird. Originally written as "鸱", the variant form adds the "bird" radical. Pronounced yuè (rising tone) Meaning is the same. Xu Collection, Middle Volume Radical: Bird (niǎo) Page 1037, Entry 06 Pronounced hé (rising tone) Quoting from Zhang Chao's "Ode to the Green-Clad Woman" (Zhang Chao·Qingqingyi Fu): "A Sui pearl to strike a kite, Tang Xi to cut mallows, a mandarin duck to peck at a mouse, how is it different from a 'gu'?" Note: Zhang Chao's ode originally wrote "鸱", which was mistakenly written as "䲻", and then further mistakenly written as "䲻". The "Zi Bu" (字彙補) incorrectly assigns the pronunciation "hé (rising tone)" to "䲻", which is a significant error.
