Ospreyers, Doesn't someone on this list work at the Paxtuent Research Center? If so, could you e-mail me privately. I'm working up my thesis proposal for studying habitat preferences of wintering waterfowl in VA and I'd like to know if any similar research has been done in the Chesapeake Bay area (or anywhere in the US for that matter). Thanks in advance. Sue -- Susan Heath Centreville, VA sheath@erols.com
