Took a walk along the Clyde at Govan this afternoon. Twenty-five Goldeneye were out in the middle of the river in front of the transport museum. Among them was a female Long-tailed Duck (link to photo by Southside Birder here). She seemed quite at home with the other birds but lunged aggressively at any that came too close. Also in the area were a Cormorant and a couple of Pied Wagtails.
