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.
Greater white-fronted geese are 64–81 cm (25–32 in) in length, have a 130–165 cm (51–65 in) wingspan, and weigh 1.93–3.31 kg (4 lb 4 oz – 7 lb 5 oz). [4] [5] They have bright orange legs and mouse-coloured upper wing-coverts. They are smaller than greylag geese. As well as being larger than the lesser white-fronted goose, the ...
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 ...
Snow geese breed from late May to mid-August, but they leave their nesting areas and spend more than half the year on their migration to-and-from warmer wintering areas. During spring migration (the reverse migration), large flocks of snow geese fly very high and migrate in large numbers along narrow corridors, more than 3,000 mi (4,800 km ...
