Grey Heron

Captured on a midday walk across the Roman Bridge of Salamanca (the origin of which dates perhaps to 16-13 BC)..  The heron was below us, providing an unusual perspective. We observed him for quite a while, but he didn't catch anything as far as we saw. The extra is utterly different:  two construction workers in the city behind a large semitransparent screen, green and blue. I promise to return tomorrow to a subject more characteristically Salamancan :)
