In addition to Deanna's reports earlier this winter, small numbers of Trumpeter Swans have been found in sw. Linn Co. and in a few other non-traditional locations in the mid-Willamette valley (Finley, Ankeny etc.) for the past several years.
This coincides with a depletion of numbers in the Airlie (s. Polk County) wintering flock, for which the highest reliable count this winter (not counting my effort to ID them well out of range of my binoculars back in November) was only about 7 birds.
The total number of Trumpeters wintering in the valley south of Portland seems to be down by at least half, and probably closer to 75%, from 10-15 years ago when flocks of 40+ were routine in the Airlie area.
