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.
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.

Canada geese, like humans, are monogamous, and couples often stay paired up for life — making an ideal home environment for orphaned goslings. Flocks will foster abandoned goslings without a peep."
For the past 10 years, Hummingbird Central has tracked hummingbirds' northward migration. Ken Freeman, a Hummingbird Central staff member, says the site relies on "citizen spotters" to report ...
Adult geese are often seen leading their goslings in a line with one parent at the front, and the other at the back of the "parade". Like most geese, the cackling goose is naturally migratory, with their overwintering range being most of the U.S. (locally in Western Canada, the West Coast of the U.S. and northern Mexico). The calls overheard ...
