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.
The greater bird-of-paradise (Paradisaea apoda) is a bird-of-paradise in the genus Paradisaea.. Carl Linnaeus named the species Paradisaea apoda, or "legless bird-of-paradise", because early trade skins to reach Europe were prepared without wings or feet by the indigenous New Guinean people; this led to the misconception that these birds were beautiful visitors from paradise that were kept ...
Waterfowl flyways in the United States. The Atlantic Flyway is in violet. The Atlantic Flyway is a major north-south flyway for migratory birds in North America. The route generally starts in Greenland, then follows the Atlantic coast of Canada, then south down the Atlantic Coast of the United States to the tropical areas of South America and the Caribbean.

The passing of the Migratory Bird Treaty Act of 1918 in the United States resulted in a need for more information on bird migration. Frederick Charles Lincoln was put in charge and improved methods for trapping and banding, developed record-keeping procedures, recruited banders, fostered international cooperation, and promoted banding as a tool for research and wildlife management.
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.
For larger birds, flying in flocks reduces the energy cost. Geese in a V formation may conserve 12–20% of the energy they would need to fly alone. [ 30 ] [ 31 ] Red knots Calidris canutus and dunlins Calidris alpina were found in radar studies to fly 5 km/h (2.5 kn) faster in flocks than when they were flying alone.
The East Atlantic Flyway is a migration route used by about 90 million birds annually, passing from their breeding areas in the United States, Canada, Greenland, Iceland, Siberia and northern Europe to wintering areas in western Europe and on to southern Africa. [1] [2] It is one of the eight major flyways used by waders and shorebirds. [3]
The bush curlew is sometimes recorded in flocks, but when the breeding season occurs, the number of birds in a locality is the usually just a mating pair. [8] Like other ground-nesting birds, the females only select a site to lay the eggs and provide no other adornment to the nest; care of the site is performed by both parents.
