A greater scaup swimming in the Milwaukee River. The scaup is surrounded by brown water in the photo. It is facing left. It has a grey bill. The head is black, but also has a green iridescence along the side. The eye is a bright yellow. The duck's breast is black, but seems to have a purplish sheen to it in this photo. The belly is white and its feathers are mottled. The tail is dark with some white spotting.
