The artificial hummingbird maneuvers using its flapping wings for propulsion and attitude control. It has a body shaped like a real hummingbird, a wingspan of 6.3 inches (160 mm), and a total flying weight of 0.67 ounces (19 g)—less than an AA battery .
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. Though machines may differ in form, they are usually built on the same scale as flying animals.
The modern concept of U.S. military UAVs is to have the various aircraft systems work together in support of personnel on the ground. The integration scheme is described in terms of a "Tier" system and is used by military planners to designate the various individual aircraft elements in an overall usage plan for integrated operations.
Using a real taxidermy pheasant head and pheasant wings, the research team tested the creation of a drone with flapping wings. The purpose was to create a drone that could more naturally blend in ...
The result of this exercise was the DelFly I, a 50 cm wingspan, 21 grams flapping wing MAV equipped with a camera. The DelFly I was able to fly both fast and perform slow hovering flight while providing reasonably stable camera images. In 2007, the DelFly II was created: a 28 cm wing span 16 gram flapping wing MAV equipped with onboard camera ...

Fleets of dozens of mysterious UFO drones are surveilling America’s most sensitive military sites, and the Pentagon admits it can’t do much to stop the aerial intruders, according to a new report.
For intelligence and reconnaissance missions, the inherent stealth of micro UAV flapping-wing ornithopters, imitating birds or insects, offers potential for covert surveillance and makes them difficult targets to bring down. Unmanned surveillance and reconnaissance aerial vehicle are used for reconnaissance, attack, demining, and target practice.
