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.
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). [43] Flying in the V formation has been the subject of study by researchers.
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. [2] [5] Alpine chough: Pyrrhocorax graculus: Corvidae: 8,000 metres (26,500 feet)
Most goslings will stay by their parents' side for the first year of life then grow apart from the adults. Young geese who fly together are known as "gang broods" and typically fly south together ...
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.
Greylag geese tend to pair bond in long-term monogamous relationships. [27] Most such pairs are probably life-long partnerships, though 5 to 8% of the pairs separate and re-mate with other geese. [27] Birds in heterosexual pairs may engage in promiscuous behavior, despite the opposition of their mates. [27]
Canton will see a large volume of birds migrate overnight this week, according to a bird migration tracker. Up to 13k birds expected to fly over Canton Wednesday night. Here's why
