The Cranes are Calling

On my after-work-walk, I heard the first cranes of the season, just when I walked under trees. I hurried to an open space, so I could see the sky, and still didn’t spot them for a while. When I finally did, they were very high up, and I only had my phone with me. 
So my attempt to blip the cranes ended in a) photos without any birds in them (on the left) and b) photos with dark, pixelated smudges (on the right).

I also added the picture of a sundial at nearby Schloss Freudenberg that I originally wanted to blip. But cranes, however pixelated, take precedence.
