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. This was when the bird flew in and landed on his spot.When all efforts failed, he resorted to Amy and Bernadette's help since they are biologists to shoo the bird away. Bernadette comments that none of their education included classes on birds and bird-shooing. The girls made him conquer his fear and he ends up being infatuated by the bird, thus the name Lovey-Dovey. He even had Bernadette took a picture of him and the bird to put it on a mug, a calendar and a mouse pad. When Sheldon decided to keep the bird, he opened the window sill to retrieve her nest and that was when Lovey-Dovey flew away. A frustrated Sheldon found his console with the bird's nest containing one egg. He eventually told Leonard that he is going to be a mother.
- Despite Sheldon claiming that Lovey-Dovey had laid eggs, they have not been mentioned since The Ornithophobia Diffusion.
- In "The Flaming Spittoon Acquisition", the picture that Bernadette took of Sheldon and Lovey-Dovey can be seen as Sheldon's profile picture on Facebook.
