worldMigrating is probably the most amazing things that birds do. Migration is when birds travel from living in one place to living in another. The time that they migrate is often decided by the seasons. We are very lucky living in the UK because our weather is ideal for birds that migrate. We have warm summers (not too hot) and cold winters (but not too cold). Our weather pattern means that some birds can stay here all year, some birds come here just for our warm (not too hot) summers and other birds come for our winter (not too cold). What makes them need to move about and make these fantastic journeys? FOOD! Because we have so many birds that migrate to and from the UK we are lucky enough to be able to have 400+ bird species on the British list. There is so much amazing science about migration that people write books about it!

We see House Martins, Swifts and swallows in the summer and then they fly south, to warmer countries in Africa, in the autumn. In the UK there are many other birds - the warblers, such as Blackcaps, Chiffchaffs (the first to arrive) Willow warblers, Cuckoos... It is a very long list! I love the arrival of the Nightingale - the beautiful song that tells me "Spring has arrived" The RSPB: Nightingale.
