Sorry for the confusion, but she did not initially breed large birds - so the youngest B&G would be about 15 and the oldest would be under 30.I'm a bit puzzled by the numbers here - I'm not sure how it's definite that the macaw is under 30. If they were breeding from 1976 and had babies then, the oldest the bird could be is 44. If the kind of band wasn't used after the mid-1980s, then we're looking at an age range of mid-thirties to mid-forties.
The youngest the macaw could be is 15 if she was one of their last chicks, which is still a couple of years older than the 11 you were told.
