That link makes me think I should just put some blinds on the window.
The Robin has to be worn out after a few hours of that.

You mean that you can see out from the basement to outside? Of course, you're on the dark side of the window which can see to the bright side. The bird is on the bright side and when it's completely dark probably just sees a reflection. As you get close enough, you break the reflection, he sees you, and then goes away.

It's similar to how in the movies when there's 1-way glass, the folks that are watching through the glass are usually in a dark room (best example that I can think of is NCIS).

light behind the window, you can see through it. Dark behind the window, it reflects light from in front.
