Lisa and others,
 
There are at least 2 different forms (morphs?) of female Eurasians; one is harder (or even impossible?) to separate from Americans in the field.  (Some guide books show 2.)  I've seen females at Stewart Lake in past years, but never one so obviously different from the Americans.  This make me wonder if there are intergrades between forms/morphs.

She really does look different from the female Americans, especially
since she has a light throat.  I never thought I would be able to pick
a female Eurasian out of the crowd.  The pictures that show her with
female Americans are helpful.  I always imagine that there are
probably twice as many Eurasians as people report -- it's just that
only the males stand out and get counted.
