Touch of nature

At first it was a hilly landscape, then for a number of years a large gravel pit.
Subsequently, the lake was established when the gravel excavation was over
So then plants took over and afterwards animals arrived, mostly birds in many sizes.

They are not at all tame, nor real wild.
They watch people move,
we are probably in the category:
gulls, loose dogs, foxes, rats and so then us humans.
