Yellow cockatiel with orange cheeks, lost near campus

I lost my yellow cockatiel, Sunny, yesterday around 3pm. He's a small parrot, about the size of a sparrow, with bright yellow feathers, gray wings, and distinct orange cheek patches. He wears a light blue plastic leg band with the number 24-BR. I last saw him near the Krannert Center for the Performing Arts on Goodwin Ave, then he flew toward Lincoln Street by the campus library. It has sentimental value—he was a gift from my daughter, and we’re really worried about him. If you spot him, please reach out. I’m ready to come collect him from Champaign Urbana as soon as possible.
