This is a video of griffon vultures flying in southern France.
In the Netherlands, the South European griffon vulture is usually a very rare bird.
However, these days one can see flocks of over fifty of them in Belgium and the southern Netherlands.
Maybe they went north because too strict rules in Spain, where they nest, against cattle carcases in nature, cause a lack of food.

It is to be hoped they will fare better than Eurasian black vulture Carmen, who died in the Netherlands a few years ago.
