Seems to me it comes down to debate about when a species becomes a
species. The current belief is that Common and Hoary do not hybridize
much. So if they consider themselves separate , who are we to argue. The
crossbill problem seems to me to be similar. Are there 10 crossbills
slowly becoming species? For that matter are the large white-headed gulls
simply a few generations ahead of the redpolls and crossbills?
