This is a video, recorded in Germany, about crane migration.
Translated from the site of Dwingelderveld national park (also in Drenthe province):
Young cranes born
This spring, for the first time baby cranes were born in Dwingelderveld. It’s been expected for a few years, because in 2004 already a crane had been discovered in the Dwingelderveld, and since 2007, there were four breeding attempts, but things always went wrong during the egg stage. Now the attempt is successful: the first young cranes hatched, after four weeks. They were two. One died after a few weeks, the other chick is doing well.
Once-common great crane back in UK: here.
At midday on 20 June 1922, a remarkable group of people from different countries met in London and concluded that the only effective answer to the threats facing birds across the continents had to be through co-ordinated international action. So was born the International Council for Bird Preservation (now BirdLife), 90 years old today: here.
