4/7/2021— This Tufted Titmouse woke me up at 8:00 AM to loud chirping and banging outside my window.
Recently, I put out a nest box on my window sill. In case my presence would deter birds from nesting in it, I applied 1-way window-film. Unfortunately, it blocks sunshine from entering my room and it’s reflective on the outside.
I believe this Titmouse was attacking his reflection, thinking it was a rival bird. (I decided to name him “Ansel,” which means “protecter.”)
I drew highlighter on the window to get him to stop, but he hasn’t come back yet so I’m not sure whether it worked or not.
I do have a bird feeder on my windowsill as well, but, since Tufted Titmouse nesting season is beginning, I figured it was probably more likely he was attacking things to protect his nesting territory or claim a new one.
Will birds attack anywhere on their territory or only near their nest? Does he want my new birdhouse?
