Driving through Prudhoe was just approaching the fire station when I spotted them flying across the road. So a quick park up in the swimming pool car park and sure enough there were seven or eight of them flying from one tree top to another in the area of the Fire station, and I had the camera.
Wigeon and Tufted Duck were present in good numbers as well as this, which at first I thought a Scaup
With reference to Collins the white band just behind the black bill tip suggests it may be a Tufted / Scaup hybrid. But most likely I've just read that female Tufted sometimes exhibit the broad white band.
