I was wondering that what if we have a bird let's suppose that I've an African Grey parrot. I feed him well , I take good care of him. What if I let him out of his cage one day , will he return back? Given that he's released into the open air.
Are you talking about letting him go outside freely? This is not a good idea for a number of reasons. I know in my area, all birds have serial numbers on their ankles and if your bird gets out, you will face a hefty fine for it. They can be very damaging to crops and cause issues with other bird populations.
