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.
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.
The black kite can reach an altitude of around 37,000 feet especially during their migratory flight to and from West Africa in the second week of September and the last week of May annually. [citation needed] Andean condor: Vultur gryphus: Cathartidae: 6,500 metres (21,300 feet) [7] Mallard: Anas platyrhynchos: Anatidae: 6,400 metres (21,000 feet)
Some geese return to the same nesting ground year after year and lay eggs with their mate, raising them in the same way each year. This is recorded from the many tagged geese which frequent the East Coast. Canada geese fly in a distinctive V-shaped flight formation, with an altitude of 1 km (3,000 feet) for migration flight.
Migrating flock Greylag goose can gather in very large flocks of thousands of individuals. Greylag geese are gregarious birds and form flocks. This has the advantage for the birds that the vigilance of some individuals in the group allows the rest to feed without having to constantly be alert to the approach of predators.
The triple whammy of record warmth, very little snow and lack of ice in Wisconsin during the winter of 2023-24 has made headlines.. The birds have noticed, too. Many species are migrating to the ...
These spatial differences lead to different departure times for white-fronted geese leaving their breeding areas. 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.
An alternative definition is that a flyway is the entire range of a migratory bird, encompassing both its breeding and non-breeding grounds, and the resting and feeding locations it uses while migrating. [2] There are four major north–south flyways in North America and six covering Eurasia, Africa, and Australasia.
