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.
A common pattern in North America is clockwise migration, where birds flying North tend to be further West, and flying South tend to shift Eastwards. Many, if not most, birds migrate in flocks. 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.
They also fly over the peaks of the Himalayas on their migratory path. [4] Whooper swan: Cygnus cygnus: 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.

Moments before the bird landed on the field, fans had spotted a flock of geese flying low near the stadium lights in a "V" formation. About 80% of birds migrate at night, preferring the cool of ...

Birds from interior Alaska start migrating earlier during autumn and fly farther south to winter. [17] Due to their migration, white-fronted geese are commonly sought after by waterfowl hunters, all across the country.
