My pet budgie flew away

Around 8-9 AM, I noticed that there was only one budgie in the cage, I thought the other one must have went in her nesting box like usual. 10 minutes passed, then 20, but she didn't come out. So I opened the nesting box aaaaand she wasn't there. Just like that, she was gone. And the thing is , I was in the same fucking room. No sound of cage opening, no sound of wings flapping, just gone.Quite a Way to start makar sankranti isn't it?
