I live on the central Jersey shore and was kayaking around in a somewhat marshy area. Low and behold i see what looks like an oversized mallard in teh reeds. I get closer and the bugger is completely black including the bill. the closest thing i could find ina book was the muscovy but I do not see how that would be too likely here. There where maybe five in the group, all totally black and larger than a mallard. I am not great with the water birds but I could not find anything on these buggers. any help here would be nice.
