[TN-Bird] Re: Duck Problems

Jeff, reading your post about mixed up ducks made me think of an article 
that I just read in On Earth, the publication of the National Resources 
Defense Council, concerning the effects of synthetic chemicals released into 
the environment on wildlife and  human reproduction. It specifically focuses 
on endocrine disruption.  It can be read at the NRDC's website: 
www.nrdc.org.  Just a thought.  Could the mixed up ducks be a mutation 
caused by the disruption of their endocrine system by man-made chemicals?
