Switched on

This morning I  thought I could see a touch of red on my favourite rowan tree on the ridge above the house.    An hour later my eye was drawn to a red splodge  further down the hill, and it turned out to be this  huge clump of rowan berries.   

Then I saw some more on a tree above the front lawn. 

It was almost as if they were all  switched on by nature today because they must have been there yesterday , and only slightly less vibrant.   Yet I didn't spot them.
