This 2015 video is called Common Cranes. Dancing birds in springtime.
From Dutch NOS TV today (translated):
There are more and more breeding cranes in the Netherlands. According to BirdLife in the Netherlands, this year there was a record number of 32 pairs, ten more than last year and four times as many as in 2014.
Twelve of the 32 breeding pairs also got chicks. BirdLife has counted twenty chicks and only seven of them fledged. This is because there was too little food because of the drought.
Also, predators could now more easily reach the nesting and sleeping places. “It is a disappointing end result”, says BirdLife.
