Parrot 911 helps return parrots, you can post there.
Also work on recall trsing in your house. Some parrots need to learn how to fly down from a high place, as if they haven't learned to fly well this is scary.
Put a little sign by each door,that says something like parrots safe?
When weather is nice, secure cage doors and feeding doors, bottom tray of cage a d roll it outside and sit with your parrot at all times. Nice for parrot and helps them learn not to freak if they get outside by mistake. There are also travel cages and packs , you an your birds can go for a walk,.
