Just a caveat - how many times do pictures get copied the wrong way
round? Or even on purpose, as it fits the overall layout better?
I found a (cheap) little booklet called 'Shorebirds of North America' (or
similar) with a frontispice of Hilbre Is, Dee Estuary, England ( it
must be cheap if they do not find a suitable picture from the area
covered) which is the mirror image.
Don't try to find your way across the tidal flats by this picture.
