Thanks, Wayne. Yes I have seen lots of evidence that certain
species including California Gull yoyo north and south during
the winter depending on conditions or food availability. I don't
remember the month off the top of my head but there was
one late fall/winter when a 5-figure group showed up in Siletz
Bay attending a baitfish run without much prior buildup.
There have actually been 3 coastal Lesser Black-backed this
fall/winter- Tillamook (1st-cycle), D River, and Alan's bird
in north Lane County. This is after (I think?) only 1 prior
coastal record ever in Oregon. Due to changing arctic/subarctic
conditions, or general expansion of this species, or possibly
both allowing more birds to reach the central/north Pacific it may
become annual in small numbers along the coast in future
years.
