Every year, the pipistrelle bat, the painted lady butterfly, the Eleonora's falcon a
nd the Blackcap undertake mysterious migrations. From North to South and East to Wes
t, from Scandinavia to South Africa and from the Baltic to the Atlantic, these anima
ls' journeys have crisscrossed all of Europe and Africa for thousands of years. Thes
e discreet journeys cover thousands of kilometres, and trigger puzzles that scientis
ts are still trying to understand today. Just over our heads, or a few miles from ou
r coasts, some of these migrations bear witness to the species' extraordinary abilit
y to adapt, incorporating changes that have been slowly forged through evolution
Others testify to the ever-increasing influence of man's impact on the environment
With the help of field experts and state-of-the-art technology, we will track these
astonishing species and hope to reveal the mysteries and secret pathways of their mi
grations Thanks to miniature transmitters, satellite monitoring and DNA analysis, th
is series uncovers incredible journeys, unsuspected behaviour and habits that are cr
ucial to the survival of these great migrators
