Birds are one of several species of animal that migrate every year. Unlike animals such as hedgehogs, mice, bears, etc they do not hibernate. Instead, they fly to another part of the planet where it will be warmer for the season – and where they can find plenty of shelter and food.
Why do birds migrate?
The main reason why birds migrate is that they know food will become scarce in winter. Most birds will migrate to places like Africa, where there will be plenty of food. Other birds change from the northern hemisphere to the southern hemisphere and vice versa – where the opposite hemisphere will become warmer as it nears to summer there.
Are there exceptions?
In places like the Amazonian Rainforest, in Brazil, birds don’t have to migrate because the Amazon is located close to the equator, in which case it would be warm in any season and there would be enough food for them to live.
However, some species of birds don’t migrate. They stay for the winter. Such birds in the northern hemisphere include blackbirds, robins, etc. They will usually feed on the berries found in hedgerows, worms and other insects and maybe bread or bird food from bird lovers.
When do birds arrive from their migration?
Birds that have migrated arrive back from early-spring to mid-spring. Usually from around March to May. A good time to spot a certain species of birds back from migration is around the first few days of May, very early in the morning (around dawn).
How many of them migrate?
The known amount of species of birds that migrate every year is 4000. That’s 40% of all the bird species on Earth. Swallows, ospreys, turtle doves, geese, Arctic terns, emus and chaffinches are among those 4000 species. Smaller birds include hummingbirds, flycatchers and warblers.
Which bird migrates the furthest?
Out of all the 4000 known species, Arctic Terns are known to travel the furthest. Each year they migrate 20,000km. They depart from Shetland to the Antarctic from the beginning of August to the end of October and they return back to Shetland from around end of March to the beginning of June.

The link to the routes of migratory animals is very nice. I found it very informative.
ReplyDeleteThanks Azka!
DeleteYour report is very interesting and it looks very Original, kenza! And we discussed the link you sent in Session 4 and we learnt new things such as the routes,speed,size,and time taken to fly(travel of migration) of migratory birds.
ReplyDeleteThank you for sending the link!
DeleteThank you so much Zainab! I'm glad you found the link interesting too! No problem! :)
DeleteThank you for posting my research work! I'm glad you found the route map interesting too! :)
