Marcia and fellow Tn-birders
Right on the money Marcia.  During the peak of summer/fall migration, 6 to 1 
is often the case.  There are a lot of hummers out there.  Martha and I have 
banded nearly 800 in our yard this season.  Less than 50 between late March 
and June 15th, all the remainder since that date. 

All of us are likely to see the last of our birds within the next two weeks 
for sure.  Anything that lingers past that date is a Ruby-throated in harms 
way (rare) or one of the western/Mexican species that winter in the eastern 
United States.  Don't be a stranger if you have a late hummer.

Our Hummer/Bird Study Group will be operating our bird banding station at 
Fort Morgan starting October 12 and closing on October 26th, 2002.  That is 
this week.  Come visit us.  Bring a folding chair and spend the day.  Bring 
mosquito repellant, you are likely to need it.

God Bless
Bob Sargent
