The Tufted Duck is an accidental visitor to Newfoundland, but seems to make it here regularly. In fact, there is one at Burton's Pond this week. I photographed this on at Quidi Vidi Lake last winter. The tufted duck resembles the Ring-neck Duck and the Scaups, but is clearly distinguishable by the scraggly tuft sticking out from the back of the head.
The above image is the male and this is the female Tufted Duck. These diving ducks can be a bit tricky to photograph as they are constantly diving for food. When not diving, they often have their beak tucked in under their wing. This is a handsome pair.
