I received the following re. albatross taxonomy from Walter Boles today:
This topic is certainly not resolved. The species concept adopted has a
considerable influence. The multi-species classification of albatrosses
being quite valid under a phylogenetic species concept. In the list, we
chose to adhere closer to the biological species concept. That said,
there is possible some evidence that some of the traditional subspecies
within one species can meet on some breeding islands without mating
(acting towards each other like species). This may indicated that,
despite the low levels of genetic divergence, the two forms are
biological species. Similar cases could be Grey and Chestnut Teal and
Masked and White-browed Woodswallows, pairs in which members cannot be
separated genetically but certainly different species.
Stay tuned.
