Yellow cockatiel with orange cheeks, missing near Broad Street

Yesterday around 3pm I lost my bright yellow cockatiel with orange cheek patches. I last saw him outside the Starbucks on Broad Street in Birmingham, near Five Ways, right in the heart of the West Midlands. He's a small cockatiel, mostly yellow on the head and chest with olive-green wings, and a silver band on his right leg. He tends to perch on my shoulder and chirps when he's excited, which makes him easier to spot in a crowd. This bird means a lot to me—he was a gift from my sister, and I’m really worried he’s out there on his own. If you spot him, please drop me a message so we can reunite him with his family.
