Right side
鸟 - pictograph of a bird in profile (eye, body, claw, tail), simplified from the more elaborate
鳥. The indexing radical, naturally so:
鸻 is a plover, one of the short-billed shorebirds that scurry along beaches and mudflats. Same bird-family:
鸡 chicken,
鸭 duck,
鹅 goose,
鹰 eagle,
鸽 dove,
鹭 egret.
