Branta canadensis occidentalis (Baird) 
The Western Canada Goose 1 
(The white-cheeked goose of previous authors) 
(Birds taken close to known breeding grounds of similarly characterized birds. Un- 
fortunately by the unbarred breasts they are all juveniles. No. 14145 by its darker 
coloration and slight crossbarring on flanks may be a yearling.)

Jv.=Juvonile. 
Subspecific Characters. Large size, dark breast and underbody, long 
bill, and feet large in proportion to the tarsus. 
Probably in size and proportions indistinguishable from canadensis, 
but differing greatly in colour of breast and underparts, which are solidly, 
except for lighter feather-tips in adult, brownish plumbeous — “hair brown” 
of Ridgway Nomenclature XLVI. There is often much rust stain that 
obscures the basic coloration. The type specimen of this race in the United 
States National Museum is an extreme sample of this adventitious color- 
ation. It seems very improbable that this large form should intergrade 
directly with little minima , although it is likely to do so with canadensis or 
the hitherto so-called hutchinsi (= the herein revised leucopareia), but 
demonstrations of these intergradations should be based on fully adult 
specimens, not light-breasted juveniles. 
Distribution. Breeding on Queen Charlotte islands and reported to 
do so on the Alaskan coast north of Prince William sound. Practically 
resident with little migrational movement. 
'Considering that the name “White-cheeked” was applied to this form under a misapprehension as to its actually 
distinctive characters, that the same name in latinized form must be revived as the scientific appellation of another 
race, and that it is not very familiar in common usage, I propose that this race be known henceforth vernacularly 
as the “Western Canada Goose”, a satisfactory descriptive title expressive of its scientific one.
