Have not seen a marbled murrelet, to my knowledge.  (They are rather small and nondescript, is my understanding, like a wren.  But I'm no birder.)  Haven't seen a spotted owl either, but a logger inlaw tells me they are around in nearby terrane.  If the loggers disturb one, or suspect they have disturbed one, the logging show is supposed to be shut down and treated like a veritable crime scene (yellow tape cordon and everything), until Fish & Game comes out to ... counsel the owls, I guess, and give an "all-clear".  (So I've been told.)

I have not seen a Coho salmon although a few reportedly spawn in the lake every year (it has a small outlet to the Pacific ocean).

I have not seen a mastodon, or a glyptodont, an allosaurus, or a Sasquatch either.  (Nor have I missed them, particularly.)
