Informal bird rescue

I met someone recently who takes in birds (mostly small birds like parakeets) locally from people who no longer want or cannot take care of them. He makes sure they are healthy, and provides care for them if they are not.
He then places them free of charge into homes that will take good care of them.
I think this is a good deal for parakeets, as I have heard more than once of people who no longer have the time or desire to have their little birds just releasing them into the wild.
I don't think this is a good choice: either the bird is unsuccessful in living in the wild and it dies, or like Quaker parakeets are so successful that possession of them is now outlawed in some jurisdictions because of the damage they are said to cause.

my uncle used to do that w/ love birds...he used to breed them too....and my ex's dad breeds birds too..and takes care of them...he takes care of parakeets to those really pretty bright ones..forgot what theyre called...to quails...but then i found out that he uses quails for a different reason which made me sad...but he helps out the other birds
