Right bird radical (Kangxi #196) — simplified from
鳥, a 5-stroke contraction of the standalone bird-pictograph (which kept the eye, beak, body, and tail). Carries the meaning:
鹅 is the domestic goose. Same radical anchors
鸡 (chicken),
鸭 (duck),
鸽 (pigeon),
鹏 (giant bird) — the whole poultry-and-bird family.
