This morning was the 2nd time in the last week that a woodpecker has woken me up early by banging on the (vinyl) bedroom window frame. Yelling at it from the bed does no good. Last time, I banged back on the window from the inside, and that didn't stop it either. Opening the curtain, window or door is a sure method to get my heart rate up even further and to make it harder for me to fall back asleep, and by then the bird is gone anyway.
