Eurasian cranes in a V formation (video) Birds flying in V formation. A V formation is a symmetric V- or chevron-shaped (or two sides of a triangle) 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.
Only 10 of the tagged geese were ever recorded above this altitude, and only one exceeded 6,500 m (21,300 ft), reaching 7,290 m (23,920 ft). All but one of these high-altitude flights were recorded at night, which along with the early morning, is the most common time of day for geese migration.

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 ...

It hosts over 250 bird species and serves as an important resting and feeding site for migrating and wintering waterfowl, [8] including more than 35,000 Canada geese and 15,000 ducks using the Atlantic Flyway during the fall migration. [9] The refuge is home to one of the highest concentrations of nesting bald eagles on the Atlantic coast. [10]
The adult geese will fly down to the ground and then "squawk" up at their babies to try and convince them to follow. It doesn't always work, however, which means the adults can be up there for a ...
