Would a domestic bird, one who has been born and raised in a cage or a pet shop where it is always given food in the exact place ever since birth, be able to survive if it escaped into a suburb with a fair amount of both trees and roads/cars/everything else one would find in a suburb? Even if its wings were not clipped?

It isnt just about finding food. Its more about predators which the bird may not have a natural instinct opr defense mechanisms to avoid. So many predators out there from other carnivorous birds to cats and dogs, rats and whatever carnivorous animals you have too, where you live.
if you bird has escaped the need to find it is urgent.

If it s a domestic bird like a parrot, then good luck . Parrots with their crazy colors and everything just draw hawks and other predators to them.

If you lost it, then call all local shelters, put up fliers, do everything you can to get it back -- quick.

If you plan on releasing it (i know some crazy folks that do that.), then think again: You won't be giving it freedom, you'll be sentencing it to death.
