Sharp-shinned Hawk Accipiter striatus:

  • White et al 2015 (HBW Alive).
  • Bildstein & Meyer 2000 (BNA Online)...
    A. s. perobscurus Snyder, 1938: Breeds on Queen Charlotte Is., British Columbia, and, possibly, adjacent mainland; partly migratory reaching Oregon and possibly farther south. Slightly darker than velox (especially in Juvenal plumage); underparts more heavily marked and white of belly reduced (Snyder 1938, Friedmann 1950). This race not recognized by Hellmayr and Conover (1949).
Great Blue Heron Ardea herodias:
  • Martínez-Vilalta et al 2016 (HBW Alive)
  • Vennesland & Butler 2011 (BNA Online)...
    A. h. fannini Chapman, 1901. Resident from sw. Alaska (Prince William Sound) south to the Queen Charlotte Is. [type locality = Skidegate, Queen Charlotte Is.]. Birds resident in sw. British Columbia, including on Vancouver I., and w. Washington are intermediate toward A. h. wardi in color and size (Dickerman 2004a,b), but the status of those on mainland British Columbia north of Vancouver is unclear. Adult dark gray; relative to populations of A. h. wardi on the southern Pacific coast, the culmen (< 134 mm) and tarsi (< 161 mm) are short (Dickerman 2004b), but wing and tail lengths are similar (see mensural data in Oberholser 1912, Dickerman 2004a).
