Was kinda hoping they wouldn't release her and that they would use her as an ambassador bird (live Bev has suggested).
For a wild breeding bird that has all its faculties, captivity as an ambassador bird can be a definite decrease in her quality of life. Peregrines are not easily trainable birds (for the most part) as adult captures and from the way this one can fight, captivity could be extremely hard on her, despite the best efforts of I'm sure some very capable and considerate people. We had a peregrine that lost its wing and therefore had to be kept and it never did calm down enough to work effectively as an ambassador. Beautiful bird, great handler, but he almost always hurt himself when he was "working". That's stressful on the bird and the handler(s).
Besides, given her willpower, determination and sheer bloody-mindedness, wouldn't you prefer those genes in the wild than her entertaining in a mall somewhere. And before you ask, putting a bird into a breeding program is just making it an ambassador, far from a guarantee and maybe not in the best interests of the bird. All are necessary and worthwhile occupations, but for this bird, which would you imagine would give her the greatest quality of life?
