I led my waterfowl class on a field trip to Sauvie Island and Dawson Creek. We had a few big misses (Gadwall and Wood Duck) but the diversity was pretty good.
Westmoreland Park, in southeast Portland, is always worth a quick visit in winter.
Westmoreland is also a good spot for studying the various subspecies of the white-cheeked goose complex. This is a Taverner’s Cackling Goose, identified by her medium bill (covered in down for some reason), blocky head, and pale breast.

I birded Ankeny National Wildlife Refuge in preparation for my waterfowl class. Waterfowl numbers have dropped considerably in the past week, suggesting that some birds have already started their northward migration.
Pintail Marsh hosted this small flock of Tundra Swans and Dusky Canada Geese. Protecting winter habitat for the rare Duskies was the main reason for establishing the Willamette Valley National Wildlife Refuge Complex.
Westmoreland Park (Birding Oregon p. 69) is one of Portland’s premier loafing spots for gulls and waterfowl in autumn and winter. The city is planning to restore the natural flow of the creek in what is now an urban duck pond, so it will be interesting to see how these changes will affect bird use over time.
This female Surf Scoter has been hanging out for about a week. She is apparently finding enough mollusks to eat in this muddy pond. A few of these sea ducks are found on the Columbia River and on larger bodies of water in winter, but they are unexpected on such a small pond.
