From the outside in daylight my large front porch windows are nearly as reflective as mirrors. Birds often mistake them for open space fly zones.
Today I watched in horror as a stalwart resolute Towhee fell for the visual illusion, flying full tilt into the window, impacting, bouncing recoiling, reversing and then trying it yet again!
The second impact bounced him out onto the lawn, where he laid stunned, feet pointing to the sky for perhaps a minute.
I watched helplessly as eventually he struggled to rise, then into the air he drunkenly took wing, away from the porch, turned and flew directly back onto his delusion of freedoms space. The sound of the impact sickened me.
One minute alive the next he lay dead on the stone porch. A victim of his instinctive inherit perseverance for freedom.
We humans; perhaps all living creatures are not so different than this little bird, our innate instincts can and often do lead us down the wrong paths, even to bad endings. I buried the little downed flyer beneath my favorite Birch tree in the garden. To ensure that our Barn Cats did not add the indignity of being eaten to the little flyer's untimely demise.
