I made essentially the same trip as the WOS April field trip to Bowerman/Ocean
Shores, only I did mine solo on Friday. I had 60+ species, including some
which were not on Scott's list:

Merlin 1 at Bowerman
Ring-necked Pheasant 1 at Damon Point
Ruffed Grouse? What looked like one on a telephone wire(!)
at the intersection of WA 115 and WA 109
Snowy Plover 3 on the ocean side of Damon Pt.
Wandering Tatler 5 on the jetty
Herring Gull Several on the jetty
Common Raven Over WA 109
Horned Lark A few on Damon Pt.

Quite a spot for birding!
