bird of prey, desolate, rough, daring, bravery
鷙 centers on the fierce, aggressive nature of a bird of prey: daring, rough, and brave. The desolate sense is a less common extension, perhaps evoking the starkness of a predator's domain.
鷙 combines 執 (which may contribute a phonetic element) with 鳥 (bird), suggesting a bird characterized by the qualities of 執—perhaps tenacity or fierceness. The exact historical development is uncertain.
A bird (鳥) that seizes and holds on tightly (執) is a bird of prey—daring, rough, and brave.
For ゴウ, imagine a bold hawk letting out a fierce 'gou!' cry as it dives: gou -> ゴウ, capturing the daring spirit of a bird of prey.
