I have seen a bass eat a baby duck before. It was awesome. There were like 9 or 10 baby ducks all in a line behind the mom, all of a sudden there is a huge splash and the momma duck is going crazy. There were feathers on the water and everything.

I have also had a 7 lber cough up some big feathers in my livewell one time. Couldnt tell what it was though.

I know Richard Watson (the guy who makes the Watson rat) also has a baby duck he used to tie. He would fish it at Havasu in the backwaters and slay them on it.
