It is suspected by the authors of these two studies that tales of the geese flying at 8,000 m (26,000 ft) are apocryphal. [8] Bar headed geese have been observed flying at 7,000 metres (23,000 ft). [9] The bar-headed goose migrates over the Himalayas to spend the winter in parts of South Asia (from Assam to as far south as Tamil Nadu. [10]
Canada geese fly in a distinctive V-shaped flight formation, with an altitude of 1 km (3,000 feet) for migration flight. The maximum flight ceiling of Canada geese is unknown, but they have been reported at 9 km (29,000 feet).
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.
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.
Upland geese occupy the southern South American Continent (southern and central Chile and Argentina) and the Falkland Islands, with a continental distribution ranging from central Chile/southern Argentina to Tierra del Fuego, near Antarctica. Lesser Magellan geese usually reside in Patagonia or southern Chile and migrate north during the winter ...
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 ...
[15] [16] Asian birds migrate to Azerbaijan, Iran, Pakistan, northern India, Bangladesh and eastward to China. [14] Greylags also occur as very rare winter migrants to South Korea and Japan. [17] In North America, there are both feral domestic geese, which are similar to greylags, and occasional vagrant greylags. [13]
The word "goose" is a direct descendant of Proto-Indo-European *ǵʰh₂éns.In Germanic languages, the root gave Old English gōs with the plural gēs and gandra (becoming Modern English goose, geese, gander, respectively), West Frisian goes, gies and guoske, Dutch: gans, New High German Gans, Gänse, and Ganter, and Old Norse gās and gæslingr, whence English gosling.
