Canvasbacks ( divers ) were the most highly prized of all duck species for table fare when market hunting was alive and well. This was especially true for Atlantic Flyway birds who fed on wild celery, wild rice & eel grass. On the west coast however, Cans are well-known to feed on dead & decayed salmon
... so don't think I'd care much for them. There is much to be said for what the birds are feeding on prior to harvesting them. While in Cuba, rice-fed Fulvous Tree Ducks come to mind as being really VERY good ! The Snow Geese feeding/grazing along the James/Hudson Bay coast in the fall ... pass !
I'll take all the wheat-fed Specklebellies the prairies have to offer, however.
In the Great Lakes area, Canvasbacks, Redheads & Ringnecks ("Diving" duck species) are much sought after table fare, and the Scaup ( Lesser & Greater / "Bluebills" ) I've had are quite acceptable with good preparation. Goldeneye (Whistlers) and Bufflehead are a little stronger in flavour (better in a stir fry) and most of my waterfowlin' buds don't bother with Ruddy's, Long-tailed (Old Squaw), Scoters ... or Mergansers of any type.
Of the Puddle ducks, Mallards, Blacks, Pintails, Wood Ducks & Blue or Green-Winged Teal all make good table birds. The bigger species are very good if they've been out on the stubble fields feeding on grain such as corn & barley, and Wood Ducks feeding on acorns are quite exceptional. When the birds are into a heavy diet of insect, crustaceans and molluscs ... such as crayfish and zebra mussels, well, they don't taste near as good. Those that hunt birds near locations such as sewage settlement ponds and the like ... well maybe that would explain a "swampy" taste !!!
Personally, I'll take a well-prepared dinner of roast Cans & Reds anyday over roast beef (and make both rare, medium rare at worst, please) Even a breast or two of grain-fed Mallard on the "barbie" gets the nod over steak
