Sheldon had tried several failed attempts to scare her away, which included knocking on the window, mimicking a cat's meow, drawing a cat's face on a paper then mimicked the cat's meow again, and trying to use his "Bird Death Ray" to shoo away the bird, which only succeeded in shattering the glass. He later put on a Boba Fett helmet, held a broom, opened the window, and tried to shoo the bird away again. The bird flew in and landed on his spot.
