Hehe since no one got it (it was just a silly little one day competition-type thing), it was taken from our roof! I've been taking all my pictures from the last few days from the windows on our roof, and this was taken looking down diagonally.
Thank you for your comments :)
I don't have a clue but it could be a kind of balcony railing.
I have good news:
The three baby robins are on their way to Meet the World. I miss them already. It was quite an emotional experience for me.
