the.com/ornithopter

A plane that flaps instead of flies, because wings worked for birds first.

means A flying machine that propels itself by flapping wings rather than using fixed wings or rotors.

from Built from Greek ornis/ornithos, 'bird,' plus pteron, 'wing' — the same pteron that gives us 'helicopter' (spiral-wing) and 'pterodactyl' (wing-finger). The term took shape in the 1800s as inventors sketched and built wing-flapping contraptions chasing the dream of true bird-like flight, long before fixed-wing planes won out as the practical path to the sky.
