Bird flight. A flock of domestic pigeons each in a different phase of its flap. 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 ...
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 ...
A tau emerald (Hemicordulia tau) dragonfly has flight muscles attached directly to its wings. Insects are the only group of invertebrates that have evolved wings and flight. Insects first flew in the Carboniferous, some 300 to 350 million years ago, making them the first animals to evolve flight.
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.
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.
Cladogram based on a study by Eric Pasquet and colleagues published in 2007. [ 1 ] The drongos are a family, Dicruridae, of passerine birds of the Old World tropics. The 31 species in the family are placed in a single genus, Dicrurus. Drongos are mostly black or dark grey, short-legged birds, with an upright stance when perched.
Many birds migrate in flocks. For larger birds, it is assumed that flying in flocks reduces energy costs. The V formation is often supposed to boost the efficiency and range of flying birds, particularly over long migratory routes. All the birds except the first fly in the upwash from one of the wingtip vortices of the bird ahead.
The bar-headed goose is one of the world's highest-flying birds, [4] having been heard flying across Mount Makalu – the fifth highest mountain on earth at 8,481 m (27,825 ft) – and apparently seen over Mount Everest – 8,848 m (29,029 ft) – although this is a second-hand report with no verification.
