This is a video of a grass snake.

Translated from RTV Oost in the Netherlands:

In the Kuinderbos near Kuinre, last year 2,500 grass snakes were born. Staatsbosbeheer says this after counting empty eggshells.

One third of young grass snakes survives into adulthood; the rest gets eaten by other animals. The numbers of grass snakes in the Kuinderbos are among the highest in the Netherlands.
