..I too have seen a couple of these "ducks" the last few times I was at the WOOD!.The ones I seen were mud-hens or coots I think is what youd call em...They normally eat weeds and other under water plant growth but they will eat bait(crawler,marshmellow,etc.) if its down there..The couple I seen were sub-surface and another was a little deeper... but I didnt notice them to be headless! I just figure they they had went down to get a bite to eat,ate something that was hung to the bottom and never saw the surface agian!There last meal so to speak! I never thought about this being done on purpose! and if they are pullin some voodoo crap that would be off the wall and weird to say the least... This was the first time Ive witness this in all my years of fishing though which now that I think about is kinda strange!..But didnt even think twice till this post...but on the other hand it sure isnt going to dent the population much as there are hunderdes of them on the lake.... as for the comis' doing it!(ahahhahahahhhaha!!) that is hilarious!!! KEEP EM BENT!!!!
