At a total loss. Bird poop IN my car?

Sorry, I have no idea where to post this, please recommend a sub if it doesn't fit here.

So, there was no bird poop in my car when I parked at work this morning. I locked my doors, my windows & moon roof were closed, I went to work.

Got out of work, found a single shat-out blueberry, and these bird poop stains on the center console. (I ate blueberries in the car this morning.) How could this have happened?? How could a bird get into a sealed car?

I did a quick scan and found no other poop, no feathers, nothing in the engine, still runs fine, I am just totally at a loss and could use any help because I feel like I'm going crazy lol.

2007 Honda CRV if that helps
