This image was one of the Top Ten Winners in the Challenge ‘All Creatures Great and Small with Attitude!’ on 2nd Feb 2017,
within group The Beauty of Nature ! , and earlier had been among works Featured there.
Duloch Park, Dunfermline, Fife, Scotland.
About 1600, Wednesday 3rd March 2010.
The crow was really perched just as shown; there’s no digital photo trickery, no combining of images, here!
The only manipulations I used?
I cropped the image to show only the bird and the trolleys;
enhanced its eye (which was in shadow) by adjusting contrast and brightness, to bring out its beadiness (!);
and edited out the supermarket name (a distraction) from the nearest handle.
