..nice all white primary feathers.
Further down river, in Dracut, I had nice looks at a drake Barrow's Goldeneye and a nearby female appeared to be a female Barrow's. Though this female's profile did not look quite Barrow's enough to me, perhaps it was just a function of the bird's posture (having its crown "slicked down"). Back in January, I had seen a female Barrow's type at this same spot, at that time I did not feel confident to call it a true Barrow's do to the head shape, though it's bill was yellow (as today's female was). Unfortunately I had left the camera in the car when I got a good look at these birds.
