[obol] [OBOL] grey headed junco

Unless curmudgeons like Contreras, Crabtree and Irons are still around in  
200 years, the discussion won't be nearly as entertaining... can you guys last  
that long?

Understand that the  Junco complex is just that—complex.  It has caused 
considerable debate  among the experts for years.  They make the Galapagos Finches 
seem stable  and clear cut.  In some birds their parentage cannot be 
adequately  determined.  Some experts say there is one species of Junco (there is no  
rationale for separating Yellow-eyed and “Red-backed” Dark-eyed Juncos) while  
others say there are six or even seven species.  We are at one point  along 
the evolutionary parade and stating what is a “species” or a  “subspecies” or 
a “form” is a lot more difficult for some birds than it is for  others.  
Wait 200 years and things should clarify. . .  .
