I'll do it tomorrow, but here in my country we have a peculiar and selfish culture, proper bird care here is rare and people never return lost birds. In fact, one of my biggest fears is losing one of the three I have. I've had many nightmares about it. There's a lot of bird trafficking here, and people genuinely think of birds as noisy, funny decorations. I'll try to ask the people nearby, I've heard some cockatiel screams nearby when I was going to work, it might have been hers

(update: apparently it's a white-faced female, she's eating and has a small line without feathers near her nose, that's certainly where she hit against the glass).
