Just to add a couple of other American Black Duck records from eastern Washington. There was one sighting near Texas Lake, Whitman
Co. on Aug. 17, 1949. And one bird that I saw was at the mouth of the Walla Walla River on Sept. 23, 1990. There could even be
more records once one starts to dig into the county list of each county.
