        Here in the northern latitudes (58N), I have always found I need to 
open at least one stop more than the "Rule" suggests. I assumed the lower 
elevation of the sun was the reason. More dirty thick atmosphere to penetrate 
means less light.

        Has anyone seen any research on this subject? Perhaps a measurement of 
the average foot-candles at solar noon for various latitudes would be in order. 
Do I hear any volunteers? I would be willing to graph the data and superimpose 
it over the waveforms of the Olympus shutter sounds to see if there is a 
correlation.;)

The last time I checked the sunny 16 rule I recall that the only area it
followed the rule was up in the sky.

I know John Gardner will react to what Ken was talking about.  If you
don't have to be particular about eagles and owls,  there are a lot of
areas in the United States where wild birds can be photographed.

It does not have to be cold Michigan or Maine.  


There are a lot of waterfowls south of here at the Chincoteaque.  I once
participated in a bird-watching field trip to that area in early
December.  There were plenty of Snow and Canada Geese.  This past fall I
sighted a Great Blue Heron a few times when I was exploring a few streams
in the Baltimore area at which to do my fine-art photography.  


Alternative to the US, might be Japan.  Because of the north-south range
the country is spread, you'll find an interesting variety of Japan. 
According to my wild bird book (in Japanese), two kinds of cranes will
come to southern Japan (where it is warmer) in the wintertime.  These
cranes, <italic>Grus vipio and Grus monacha, </italic>are in Southeast
Asia only.  The pictures I am looking at in the book were taken in
January and February.<italic>  </italic>You know Olympus Japan has a
network of service centers, so you can visit one of those when you are
out there.  Staying at a hotel in Tokyo is very, very expensive, but I
would think that staying in the farming areas of southern Japan won't be
as bad.  If you are interested in either Japan or the eastern US, let me
know.
