How do butterflies migrate over such long distances?
Butterflies migrate by using environmental cues like the sun, wind, and seasonal changes, often travelling in generations rather than one individual round trip. The monarch butterfly is famous for journeys of thousands of kilometres.
Which animal has the longest migration in the ocean?
The Arctic tern is famous for the longest migration of any animal, and it migrates through the oceans from the Arctic to the Antarctic and back.
Why do some birds migrate by night?
Night migration helps birds avoid daytime heat and some predators, and it can make navigation by stars and magnetic cues easier. It also leaves the day free for feeding.
Why do salmon swim upstream to spawn?
Salmon return to freshwater to lay eggs because their life cycle is split between ocean and river habitats. Many species also navigate back to their natal rivers using smell and other cues.
What is a migratory flyway?
A migratory flyway is a major route used by birds during seasonal migration. These routes connect breeding and wintering grounds across continents.
What is a stopover site in bird migration?

When was the first long-distance bird migration tracked by science?

Which bird migrates at the fastest recorded ground speed?
The common swift is among the fastest migratory birds, with rapid, energy-efficient travel that can exceed 100 km/h in favorable conditions.
Which bird has the largest migration distance between breeding and wintering grounds?
The Arctic tern is the classic record-holder, moving between Arctic breeding areas and Antarctic waters each year over a distance of about 70,000 kilometers round trip.
Which sea turtle makes the longest migrations?
Leatherback turtles make some of the longest migrations of any reptile, with some traveling thousands of kilometers across oceans.
