Yes sad and sadlier is that his tale is not uncommon. All birds want to be free birds (and should be IMO). But pet birds sometimes escape and usually meet a dire fate. At least this guy was safe from prey by a hungry fox or coyote, or rascal dog, cat...endless dangers out there.
You did a good thing Dave.
He looks both grateful and happy in both your pictures.
our best to you and Kirsten, suzie
