On the 1st February 2010 BirdLife International has officially started the annual Spring Alive Campaign. What is it all about? From now until the end of Spring, children from all around Europe will observe and record their first personal sightings of four migratory bird species: White Stork, Barn Swallow, Common Swift and Common Cuckoo. With those observations BirdLife creates a map showing when and how these birds arrive in Europe, in other words, how spring progresses throughout Europe. Good luck with your observations!
