Thank you, Andrew, for photos of the real bird. Here is another Lanius cristatus. Identified by Anthony Furness http://anthonyfurnessphoto.se from our painting.
Lanius cristatus
He/she is from this beautiful Japanese watercolour that I have known all my life and now have the good fortune to own.
Yes, 2 of them in our garden today. Brown Shrikes both, Lanius cristatus. They speak for themselves. Enjoy.

Very interesting, Hilary. It is a different race from ours as we see lucionensis which has a pale grey forehead. The richness of the colour suggests a male but perhaps not.
I saw that it was a little different from yours. I’m just amazed that the artist painted this bird in such detail that we (or those who’s are expert enough) can recognise it.
