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.
Flock (birds) Red-billed queleas form enormous flocks—sometimes tens of thousands strong. A flock is a gathering of individual birds to forage or travel collectively. [1] Avian flocks are typically associated with migration. Flocking also offers foraging benefits and protection from predators, although flocking can have costs for individual ...
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 ...
A swarm-like flock of starlings. Flocking is the behavior exhibited when a group of birds, called a flock, are foraging or in flight. Sheep and goats also exhibit flocking behavior. Computer simulations and mathematical models that have been developed to emulate the flocking behaviours of birds can also generally be applied to the "flocking ...
In fall and winter, local birds will flock together, while many in the north will move down south to spend the cold months, according to the Carolina Bird Club. When spring comes, adult American ...
A flock of barnacle geese during autumn migration. Examples of long-distance bird migration routes. Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Migration is inherently risky, due to predation and mortality.
Birds are typically observed to fly in V-shaped formations or J-shaped formations, the latter commonly known as echelon. The first study to attempt to quantify the energy saving of a large flock of birds was Lissaman & Schollenberger [6] who provided the first, albeit notably flawed, [1] estimate for a 25-member flock of birds. A most ...
When in a flock, the birds take off almost simultaneously, wheel and turn in unison, form a compact mass or trail off into a wispy stream, bunch up again and land in a coordinated fashion. [20] Common starling on migration can fly at 60–80 km/h (37–50 mph) and cover up to 1,000–1,500 km (620–930 mi). [24]
