How do birds migrate long distances?
Birds have fascinated humans for centuries with their ability to fly. But what’s even more impressive is their ability to migrate long distances, often crossing continents and oceans. How do they do it? Let’s take a closer look.
Why do birds migrate?
Birds migrate for various reasons, including breeding, feeding, and avoiding harsh weather conditions. In the northern hemisphere, many birds breed during the summer months when food is abundant. As winter approaches, the food supply dwindles, and temperatures drop, making it difficult for them to survive. To escape the harsh conditions, many birds fly to warmer regions where food is available.
How do birds navigate during migration?
Scientists believe that birds use a combination of celestial and terrestrial cues to navigate during migration. Birds can detect the earth’s magnetic field, which helps them navigate directionally. They also use the sun and stars to navigate during the day and night. Some birds can even detect the polarization of light, which helps them determine their location.
What are some of the longest migrating birds?
The Arctic Tern holds the record for the longest migration of any bird. They fly from their breeding grounds in the Arctic to their wintering grounds in the Antarctic, covering a distance of around 70,900 kilometers each year.
The Bar-tailed Godwit holds the record for the longest non-stop flight of any bird, flying over 11,200 kilometers from Alaska to New Zealand without stopping.
Which birds migrate to and from South Africa?
South Africa is a popular destination for many migratory birds. One of the most famous is the European Bee-eater, which migrates from Europe to South Africa each year to breed.
The Amur Falcon is another bird that migrates to South Africa from Asia, covering a distance of over 12,900 kilometers.
The Lesser Flamingo also migrates to South Africa from various parts of Africa to breed.
