I know. It is sad. I have one big window I need to do something about. I've had a couple of bluejays crash into it, even with the curtains closed. And lately, some of the finches have been flying up under the patio at the kitchen window. No crashes, but it's very strange. The finch feeders have always been along the edge of the patio and there have always been a lot of finches, but they just started the buzzing the window things....and it isn't because the feeders are empty.
