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.
