An adolescent robin took refuge on our back patio (under the big oak tree) during a huge rainstorm a few weeks ago. That he would poop on the chair he was perched on was inevitable. Luckily, this chair is very easy to clean up.
Watching the birds around my house brings me great joy. Even when they shit all over my stuff. Shit happens in the course of living an awesome life. Deal with it and move on.
You don't need to ignore the shit or pretend it isn't happening, but sometimes you might and that's ok, too, I suppose. As long as it isn't hurting anyone. I could have cropped the photo so you didn't see the guano, but I decided not to. Shit happens. It's part of life. And I don't want to ignore that, even in a photo of an adorable adolescent robin.
