Thanks to Marty Freeland (see below), I learned that recent taxonomic
changes "lumped" the former Rock Thrush Monticola saxatilis with the Blue
Rock Thrush Monticola solitarius. Therefore both the bird photographed in
Washington and on the Farallon Islands are indeed Blue Rock Thrushes,
probably of the migratory form philippensis. Sorry for the confusion.

"Under current Clements/eBird taxonomy, there is no longer any species
recognized as "Rock Thrush."
The Farallones bird is an example of the taxon currently treated as
subspecies philippensis of the Blue Rock-Thrush. This race is highly
migratory.
Additional information about the systematics, distribution, and movement of
the Blue Rock-Thrush complex is available at (for example) Cornell
University's Birds of the World site
