Most parrot rescues for unwanted pet birds deliberately try to keep their locations a secret. When some of those bird species can retail for several thousands of dollars, there is a strong incentive for criminals to get there hands on these animals. Hopefully it wasn't some nut that released them into the wild. They will be cat or hawk food in less than a week, providing they don't starve becassue they don't no how to forage.
I had a cockatiel get out once (I don't clip their wings). She was kinda fussy and I always joked about "she doesn't like me".
But within 2 days, she literally flew in and landed at my feet. As if to say "It's SCARY out there, and I'm hungry!!"
