Dan Singer, Robbie Fischer and I decided to swing by the Willow Springs Pond at the end of King Road in Soulsbyville on our way to Southern California. Numerous birders were already enjoying fine views of the Smew when we arrived. I studied the bird through a Nikon FieldScope and took some digiscoped photos by hand-holding my Olympus D550z up to the scope. You can see the results here. Photography was difficult because the bird was diving almost constantly. It associated loosely with a group of 2 male and 3 female Hooded Mergansers (Lophodytes cucullatus).


It was a striking small black and white duck. The plumage was mostly white, with bold black patches around and below each eye and two black lateral stripes on each side of its head, below a loose white crest. These black stripes formed a point on each side of the nape, but did not appear to connect behind the head (some photos show the black connecting at the nape). The scapulars were white contrasting with a solid black stripe down the back and outlined by a thin black line below along the sides. The breast was white with a faint gray line extending forward from the shoulder and a second better defined black stripe extending straight down to the waterline from the shoulder. The sides and flanks were white with fine gray vermiculations. The narrow wedge-shaped bill was short, thin and dark gray with an evident raised round nostril about half way down. The eyes and feet appeared dark. Overall the bird seemed smaller and more petite than the adjacent Hooded Mergansers.


This bird was first seen 20 January 2007 by Steven Umland who was initially unable to identify it because this species is not included in the Sibley Guide to Birds. Later he found the species illustrated in the National Geographic Field Guide to Birds of North America and put out the word. It was confirmed and photographed 21 January 2007. It left the pond each night but usually returned the next day. It was missed 27 January and has not been seen since 30 January.

There has been some speculation on whether this bird might be an escape from captivity. Observers have noted that the bird is unbanded, appears to have its rear toes intact, does not come in to grub for handouts with the domestic ducks, and is relatively rare and expensive in captivity. It is native to northern Eurasia and winters in northern Africa, eastern China, Korea and Japan. In Alaska, it migrates regularly through the Aleutian Islands and occurs occasionally in the Pribilofs and on Kodiak Island. Further south in North America, there are at least three records from British Columbia and there is a record along the Columbia River on the Washington/Oregon border. Vagrants have also been reported from Ontario, New York and Rhode Island.

Prior records from California include one seen in January 2000 near Tracy in San Joaquin County discussed here. A brief video of that bird obtained by Maya Decker is available online here. There is also a record of a male returning for three consecutive winters at Foster City, San Mateo County starting December 1981. Additional information on that bird is available here and here. A briefly described 1995 claim of this species from Buena Vista Lake in Kern County was not accepted by the California Bird Records Committee. See here for details.
