Michael,

Since the last nesting reports in the 1920s there have been just a handful
of records (note the precision of my summary). A bird was found dead in
Beaux Arts on the east side of Lake Washington opposite Seattle, King. Co.,
10 July 1974; another was calling near Sultan, Snohomish Co. for a few days
in July 1979. And there have been at least two more recent east side
records. Russell Rogers has all the data in his data base.
