Tufted Duck x Scaup hybrid

On March 20th, while scanning the scaup flock from the West Haven Boat Ramp, I noticed a hybrid Tufted Duck. Luckily there were no tense moments here - with the sun at my back, though the bird was distant, the dark gray (not black) back and short, blunt-ended tuft immediately declared this bird as a scaup hybrid and not a bona fide Tufted. While a pure TUDU would have been preferred, this is a life hybrid, and a cool one at that.

The bird was too far to document by handheld phone-scoping. I tried. As luck would have it, I put my boat in the water early this year, and it happened to be located in this very same harbor. I hopped on the boat and tried to approach the scaup flocks, a process that turned out more difficult than I had hoped. The flocks were flighty. I've gotten close to ducks in this boat before, but it usually takes finesse. These flocks, though, were especially spooky.

I eventually refound the bird among the scattered Greater Scaup flocks and got as close as I could (which was not very close at all). Still, record photos were obtained.


did look rather black-backed at certain angles

Separating scaup from each other can be difficult enough, so confidently assigning the scaup parent to species is a whole other level of difficulty. Comments are welcome, as always.

  1. Looks like possibly a Greater X Tufted, but I am no expert with hybrids (:
