This is a Hazel (Corylus avellana) bush during a summer shower.
Now leaves should be falling, but this year they don't fall that much. To turn yellow or red and to detach themselves from the branches, they need some cold days or nights. Well, this autumn is too warm, so there is still a lot of green in the forest.
Those Hazel leaves, oval shaped, dented, with visible veins and a typical little point at the end, got paler, but just a little bit.
There are individual differences between bushes, all the same. Under a Hazel a bit further on there are already a lot of fallen leaves.
In some weeks there will be nothing but naked boughs.
An old Hazel bush looks like a big bunch of trunks and branches that come out of the ground at roughly the same spot; when the oldest of them die, new shoots develop near them.
