Okay, now can someone tell me -- given that the Wikipedia article mentioned a zone of overlap between "Pacific" wren and winter wren -- how to tell them apart?  I am skeptical of cryptospecies; if there really is assortative mating, then the two species must be able to tell each other apart -- and if you can explain how they tell each other apart, you have just provided me also with a way to tell them apart.  Like the former rufous-sided towhees: one has spots on the wings, one does not, and the songs sound different, okay, I accept Eastern towhee and spotted towhee.  But American crow vs. Northwestern crow -- since no one has ever been able to tell me any consistent differences between them, I am of the opinion that they are indeed conspecific.

So: how can I tell the difference between a Pacific wren and a winter wren, if I am in the zone of overlap?

So my question:  It this Pacific / Winter Wren nesting an outlier for the
Greater Puget Sound Terrestrial Lowland community?  and if it is an
outlier, how much of one is it?
