The queer case of the peculiarly beautiful bird outside the glass window...

It was a summer evening and one of the few favourite professors had just dismissed the Manufacturing Strategy class, having passionately discussed lean production with a somewhat interested class.
"He" had, without being his unusual self, given the slip to the professor and others, disappearing in a nonchalant manner soon after the class was over.

The next ten minutes were a Godsend.

Going down the solitary stair corridor (there is only one in the institute after all!) He saw a peculiarly beautiful bird outside the glass windows. They were all shut, and the bird was repeatedly hitting the glass with its beak, trying to get in.
It was probably male, given that its feathers on its crown were a golden red while the rest of its body was covered in feathers of another gradient shade.

If He tried to open the window for the bird, He would scare it away.
He wanted to let it in.
But after a full ten minutes, the bird finally flew away.

So what if he now opened one of the windows?

He waited for a while before the corridor became busy.


Just outside the institute building, other birds were flying and people were volunteering for shots.
The shots originated in a camera of course...
