  2. Bird flight - Wikipedia

    en.wikipedia.org/wiki/Bird_flight

    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.

  3. List of soaring birds - Wikipedia

    en.wikipedia.org/wiki/List_of_soaring_birds

    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. [1] Bird of prey.

  4. List of birds by flight speed - Wikipedia

    en.wikipedia.org/wiki/List_of_birds_by_flight_speed

    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.

  5. List of birds by flight heights - Wikipedia

    Bird Image Species Family Maximum height Details Rüppell's vulture: Gyps rueppellii: Accipitridae: 11,300 metres (37,100 feet). [1] [2] Vultures use their excellent eyesight to scan the landscape below from a relatively static aerial position. Instead of flying over a larger distance, they use elevation to expand their field of vision. [3]

  6. Flying and gliding animals - Wikipedia

    en.wikipedia.org/wiki/Flying_and_gliding_animals

    The smallest flying vertebrates are the bee hummingbird and the bumblebee bat, both of which may weigh less than 2 grams (0.071 oz). They are thought to represent the lower size limit for endotherm flight. [citation needed] The smallest flying invertebrate is a fairyfly wasp species, Kikiki huna, at 0.15 mm (0.0059 in) (150 μm). [23] Fastest.

    The table contains a list of the largest birds living on this planet by wingspan, at maximum, assumed to be reliable by experts and verified records, at least 3 m (9 ft 10 in). Rank Image

  8. V formation - Wikipedia

    en.wikipedia.org/wiki/V_formation

    Eurasian cranes in a V formation (video) Birds flying in V formation. A V formation is a symmetric V- or chevron-shaped flight formation.In nature, it occurs among geese, swans, ducks, and other migratory birds, improving their energy efficiency, while in human aviation, it is used mostly in military aviation, air shows, and occasionally commercial aviation.

  9. Origin of avian flight - Wikipedia

    en.wikipedia.org/wiki/Origin_of_avian_flight

    In order for birds to balance these forces, certain physical characteristics are required. Asymmetrical wing feathers, found on all flying birds with the exception of hummingbirds, help in the production of thrust and lift. Anything that moves through the air produces drag due to friction. The aerodynamic body of a bird can reduce drag, but ...
