F---ing Robin, Part 2

OK I woke up today and that freakin' bird was back at it, attacking the same glass door. All he does is poop on the patio and then flap into the sliding door. He doesn't even try other windows, it's just the same spot every time. I have no idea what he wants.

Here are some videos I took of this bird bein' stupid.

That bird was so dumb, the perspective of this drawing is all wrong.
