Duck eating quality os a function of what they eat and the quality of the water they swim in. Lots of mallards here are hprrible, eating nothing but salmon eggs for months. Bufflehead are usually excellant, sprig too.
I've heard that from a few people. That mallards in South Alaska taste like old fish. Kinda crazy.
All they eat around here is rice, rice and more rice.
I made some speckled goose breast prosciutto recently.
Pretty good, a little greasy, but good with cheese and crackers.
