Muscicapa guttata

Pallas

, 1811,

Kodiak Island, Alaska

.

In the past placed in genus Hylocichla. Races form three groups, differing in size and plumage coloration: Pacific coast “guttatus group”, typically small, brown above, with grey-washed flanks; interior mountain “auduboni group”, typically large, greyish and paler above, with more extensive and contrasting spotting below; and E “faxoni group”, typically mid-sized, dull brown above, flanks washed tawny-buff. Up to 15 races sometimes recognized, but geographical variation to some extent clinal; euborius regarded as synonymous with nominate; jewetti and oromelus with slevini; munroi with auduboni; and osgoodi, verecundus and vaccinius with nanus. Eight subspecies currently recognized.
