My male budgerigar flew away unintentionally (I didn't think he wanted to escape) last Saturday when I was cleaning the cage. I could see him flying in a confused way. I still have a female in the cage and she chirps loudly a lot these few days. She and I miss the male. I should have clipped off some of his aviation feather... 1) Is there any chance he will fly back here? 2) I know budgerigars are hardy but will he survive outside?
