The red dot in Merlin indicates that the identified species is rare in the region of the recording. Therefore, you would have less confidence that the identification, based on song or call, is correct.
The only species on your list that I might have some reservations about would be the American pipit because of the habitat around your place (but it could have been caught on migration). Others, like Townsend's warbler, Hutton's vireo, or Fox sparrow would not surprise me. All three are present at low densities and are often cryptic / shyer. The white-throated sparrow is a Canadian prairies / Eastern Canada / New York / New England member of the white-crowned / golden-crowned group (genus
Zonotrichia). But there are often a few birds observed reliably in the PNW and there are birds that overwinter in coastal Oregon and California according to the
distribution map in All About Birds.
