Lesser flamingos flying in formation. When in gliding flight, the upward aerodynamic force is equal to the weight.In gliding flight, no propulsion is used; the energy to counteract the energy loss due to aerodynamic drag is either taken from the potential energy of the bird, resulting in a descending flight, or is replaced by rising air currents ("thermals"), referred to as soaring flight.
The red kite soaring.. This is a list of soaring birds, which are birds that can maintain flight without wing flapping, using rising air currents.Many gliding birds are able to "lock" their extended wings by means of a specialized tendon.
This is a list of the fastest flying birds in the world. A bird's velocity is necessarily variable; a hunting bird will reach much greater speeds while diving to catch prey than when flying horizontally. The bird that can achieve the greatest airspeed is the peregrine falcon (Falco peregrinus), able to exceed 320 km/h (200 mph) in its dives.
Anatidae. 8,200 metres (27,000 feet) This height was attained by a flock of whooper swans flying over Northern Ireland, and recorded by radar. [2][5] Alpine chough. Pyrrhocorax graculus. Corvidae. 8,000 metres (26,500 feet) This height was recorded on Mount Everest.
Dynamic soaring is a flying technique used to gain energy by repeatedly crossing the boundary between air masses of different velocity.Such zones of wind gradient are generally found close to obstacles and close to the surface, so the technique is mainly of use to birds and operators of radio-controlled gliders, but glider pilots are sometimes able to soar dynamically in meteorological wind ...
Rüppell's vulture (Gyps rueppelli), also called Rüppell's griffon vulture, named after Eduard Rüppell, is a large bird of prey, mainly native to the Sahel region and East Africa. The former population of 22,000 has been decreasing due to loss of habitat, incidental poisoning, and other factors. [3] Known also as Rüppell's griffon, Rueppell ...
The Andean condor (Vultur gryphus) is a South American New World vulture and is the only member of the genus Vultur. It is found in the Andes mountains and adjacent Pacific coasts of western South America. With a maximum wingspan of 3.3 m (10 ft 10 in) and weight of 15 kg (33 lb), the Andean condor is one of the largest flying birds in the ...
Ornithopter. Pteryx Skybird radio-controlled ornithopter. 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 ...
