Camouflaged Magpies

Took a walk down to Älandsbro for some lazy exercise. It’s lazy because it’s either flat or downhill nearly all the way but I’m just slightly under the weather so lazy exercise is good, definitely better than no exercise.
I passed this tree on the way and liked the mix of blue sky and white cloud behind the near silhouette.
As I took the picture a magpie flew out of the tree and once home I noticed two others sitting there.  Close inspection revealed five magpies perched there but in these conditions black and white patterning provides great camouflage.
