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?
