  2. Bird flight - Wikipedia

    en.wikipedia.org/wiki/Bird_flight

    Bird flight is the primary mode of locomotion used by most bird species in which birds take off and fly. Flight assists birds with feeding, breeding, avoiding predators, and migrating. Bird flight includes multiple types of motion, including hovering, taking off, and landing, involving many complex movements.

    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.

  4. 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 ...

    However, some creatures can stay in the same spot, known as hovering, either by rapidly flapping the wings, as do hummingbirds, hoverflies, dragonflies, and some others, or carefully using thermals, as do some birds of prey. The slowest flying non-hovering bird recorded is the American woodcock, at 8 kilometres per hour (5.0 mph). [26]

  6. List of birds by flight heights - Wikipedia

    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] A bird strike was recorded at this height in 1973. Common crane: Grus grus: Gruidae: 10,000 metres (33,000 feet)

  8. Delta formation - Wikipedia

    en.wikipedia.org/wiki/Delta_Formation

    Birds use the delta formation to fly farther when they are flying as a group. In order to maximize the effect birds will switch the lead when they get tired to allow the flock to fly farther. Birds have evolved to maximize the formation and can sense the birds around them and can position themselves in the best possible spot.
