[obol] Winter bird songs

[Darrel Faxon]

Lars,
   Interesting. I have noted ( and marvelled) in years past that Song 
Sparrows will begin to tune up the day of the winter solstice, or even a few 
days before, if the weather is clear.  Since the earliest sunset actually 
comes some time before the solstice, and by Dec. 21 has already started back 
the other way, it intrigues me that the sparrows apparently are fine tuned 
to the change.  But I have noticed them singing here in Lincoln County for 
about a week already, and to my knowledge, such an early start is 
unprecedented.
