Some days you are the window.
Some days you are the bird.
For the record, I always feel bad when a bird flies into one of our windows. We have adjusted our annual window-cleaning time (we do it in fall or very early spring when migrating birds have departed or have not yet returned). We have also experimented with different curtains that could discourage birds from flying into the window (we have no idea if anything works).
Unfortunately, everyone has days like this. I was not at home when this bird imprint was made on the window, but I didn’t find a pile of feathers below the window. I hope that means the outcome for the bird was better than expected.
Sometimes, that is all the victory you can wish for.
