WE HAVE BIRD!
Perhaps some of you birders out there may know what is going on here. Briefly, there is a small sparrow that has fallen in love with our passenger side bedroom window. There are two other, much larger windows on that side of the rig, but he continues to haunt that one.
Here is the routine: As the clock strikes eight o'clock in the morning, he lands on the tiny edge of the window and jumps straight up - much like I've seen bunnies in the desert do - and pecks at the top of the window frame. He is able to sustain this behaviour for hours on end, with a few coffee breaks in between - this is, after all, the Pacific Northwest! We thought there might be bugs there that he was eating, but no sign of anything.
Because my husband is strictly a night person, this bird was creating a very unpleasant situation for sleeping in mornings. So we put some clear duct tape on the window frame to discourage his landing there. Well, it didn't stick entirely, thus provided a suitable purchase for him. Took that down and put up a piece of heavy plastic over the side of the window that he had been attacking. Not surprisingly, he moved to the other half of the window, although this proved more difficult for him.
So another piece of plastic was needed. This time we used a black plastic leaf bag - tres elegante! But it seems to have done the trick. For two mornings in a row, there has been no bird at the window at any time of the day.
We are assuming that he could see the reflection of the forest of trees that surrounds us, and that he was trying to fly into said trees, but his brain was apparently not firing on all its cylinders to give him the message that he wasn't actually landing in a tree!!
