[va-richmond-general] Re: 90% of trees

Here in Fayetteville, NC, my normal daily bird list varies from about 15 
to 20, rarely going as high as 25.  However, those 15 to 20 come from a 
group of 40 to 50 species, so to consistently identify the birds I see 
regularly, I have to know about 45 species.
