At Broughton Beach on the Columbia River in Multnomah County, Greater and
Lesser Scaup are present in nearly equal numbers. I recall Shawneen
Finnegan and Dave Irons once took on the herculean task of counting all of
the scaup present one winter day. I no longer recall the exact numbers but
believe they counted several thousand scaup and the ratio was somewhere
near 60:40. Perhaps they, or someone else, can correct me or provide the
actual numbers.
But in certain inland places, Great Scaup are quite common.
