Building nests!

I wanted to attend the departmental interview rounds for one post of full-time professorship at the university today.  As PhD students we were invited to be present.  However, was stuck in traffic and didn't reach in time.  So I was waiting outside the room, just in case someone else comes out and I could sneak in.  Then I decided to sit in the PhD room exactly opposite to the room where the interviews were being conducted.  As I opened the room, I saw a pigeon inside and then noticed one of the windows slightly open.  I chased the pigeon out but by then realized that it had been in for some days.  Just as I was hoping that it had not built its nest, I saw it under the table - not exactly a full-fledged nest but some twigs and leaves.  What's more, found two eggs in it! 

My desire to join in the interview presentations and questions flew out of the window, just as the pigeon!  I then searched and found a small lid, big enough for the pigeon to sit in, and then tried to re-arrange the twigs; placed the eggs in it and put the whole thing on the window sill outside.  But then had doubts if the eggs would roll down and crash on the pavement below.  Moreover the sun was beating hard and directly on the eggs - not a good thing!  So then, searched for a cardboard box, placed the whole thing inside the box.  But then it occurred to me that someone might accidentally grab the box in - and thereby disturb the 'ongoing construction of the nest' and break the eggs.  So put a small note on it.
