One way to look at birds which are off-course is that they can be, figuratively, examples of nature's experimentation. If there is pressure on the birds in their natural habitat, as Tom surmises, and some genetic variation leads a bird to a new and SUCCESSFUL migration path, then it might be the start of a new population. Such adaptations have been ongoing as long as there have been birds; contemplating how our Connecticut birds became established since CT was under a mile of ice just 10 thousand years ago is something I find endlessly fascinating. I, for one, think that nature's track record at adapting successfully is better than man's track record is for trying to intercede.
