Mystery Window with Birds

I took this around the corner from our building, on the short Passage Foubert, going to our local supermarket. The window is on the first floor (the first above the ground floor), and I stretched as high as I could to take the shot; the lower border is exactly at the bottom of the window. The reflected windows are in a big apartment building across the street behind me.

I'd like to take more birds, but that's not possible in Paris. I've added this to my reflections series.
