We,ve got a bag limit on Fulvous Tree Ducks in our Md. hunting regs. I,ve been duck hunting since about 20 and am 65 now and have yet to see one or here of one killed on the Eastern Shore of Md. With some of our wardens not being able to distinguish between a hen mallard and a Blk. Dk. would be kinda nice to see what their call was on one of those in the bag when checked!
