An ornithopter (from Greek ornis, ornith-'bird' and pteron 'wing') is an aircraft that flies by flapping its wings. Designers sought to imitate the flapping-wing flight of birds, bats, and insects. Designers sought to imitate the flapping-wing flight of birds, bats, and insects.
The history of ornithology largely reflects the trends in the history of biology, as well as many other scientific disciplines, including ecology, anatomy, physiology, paleontology, and more recently, molecular biology. Trends include the move from mere descriptions to the identification of patterns, thus towards elucidating the processes that ...
Terrestrial Entomopter model. An Entomopter is an aircraft that flies using the wing-flapping aerodynamics of an insect. The word is derived from entomo (meaning insect: as in entomology) + pteron (meaning wing).
The Snowbird is a human-powered ornithopter that was built as a project of the University of Toronto Institute for Aerospace Studies (UTIAS). Snowbird was the first human-powered ornithopter to fly straight and level.

Ornithopoda (/ ˌ ɔːr n ə ˈ θ ɒ p ə d ə /) [2] is a clade of ornithischian dinosaurs, called ornithopods (/ ˈ ɔːr n ə θ ə ˌ p ɒ d z, ɔːr ˈ n ɪ θ-/). [3] [4] They represent one of the most successful groups of herbivorous dinosaurs during the Cretaceous.
Ornithoptera alexandrae, the Queen Alexandra's birdwing, is the largest species of butterfly in the world, with females reaching wingspans slightly in excess of 25 to 28 cm (10 to 11 in).
Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly.
