They're definitely alive, and protection is likely. Just don't know what species.

Pacific Wren sightings in the date and location range:

Time of sighting is wrong for a House Wren. I would have said Winter Wren, but the classifications have changed in the past few years. I think maybe it's a Pacific Wren (Troglodytes pacificus).

Thanks for the ID, Reza Hashemizadeh!

Thanks for the ID, Jakubko!
The photo on the Cornell Lab of Ornithology website looks almost exactly like mine. Apparently hermit thrushes tend to perch like that...

Thank you, Gully.Moy!
