We have rather a large garden with bird feeders at the far end, in the line of sight. However, if we make a move our feathered friends see us and scarper so it's difficult to get good shots of them. In the first picture you can see how far away the feeders are... to get that picture my camera was on full zoom. Of course you can't see what I was trying to capture, but the second photo reveals all. I enlarged the same picture, using the camera's own facility, so that we could see who has been pinching all the birdseed. Because of all the messing about the picture is poor quality but you can make out the perpetrator of the crime.
