What a cutie! PLEASE, before you start trying to get the bird to get attached to you home, put an ad in the paper, post something about it on the internet, and try EVERYTHING you can to find the owner. I bet the owner is missing their birdie terribly, and is probably worried sick.

As for the wing clipping, it would be best (In my opinion) to bring it to the vet, get it's wings clipped, and have it get a checkup-- in case any injuries occured during the flight.

Good luck, and keep us updated!
