As I was heading down my driveway this morning, I noticed
a single Three-spined Stickleback (a small estuarine fish,
common to the region). I live on the ridge of Astoria
at about 50m (according to my no longer military-offset
GPS) and while my driveway was wet with rain, I would not
describe it as particularly good stickleback habitat.
There were also a couple of nearby clumps of what appeared
to be fish scale and small bones.

My guess would be Caspian Tern barf, but as everyone knows,
they eat only salmonids.
