AT this time of year people living in France roughly from the north east corner to the south west will spot a real wonder of nature.
The migratory route of the crane (la grue) from northern Europe to Spain sees the birds cross over France, and the massive flocks high in the sky are a real sight to see.
It is estimated that there are around 160,000 birds in the west of Europe and when migrating they fly at an altitude of between 200m and 1km.
For more details take a look at the European Crane Working Group.
