After lengthy discussion it is pretty well settled that the Crow of the
northwestern sea-coasts is merely a dwarfed race of the _Corvus
brachyrhynchos_ group; and that it shades perfectly into the prevailing
western type, _C. b. hesperis_, wherever that species occupies adjacent
regions. This area of intergradation lies chiefly south and west of
Puget Sound, in Washington; for the Crow is ever fond of the half-open
country, and does not take kindly to the unmitigated forest depths, save
where, as in the case of the Fish Crow, he may find relief upon the
broad expanses of shore and tide-flats. The case is quite analogous to
that of native man. The larger, more robust types were found in the
eastern interior, while those tribes which were confined exclusively to
residence upon the sea-shore tended to become dwarfed and stunted; and
the region of intergradation lay not chiefly along the western slopes of
the Cascades with their crushing weight of tall timber, but in the
prairie regions bordering Puget Sound upon the south.
It is impossible, therefore, to pronounce with certainty upon the
subspecific identity of Crows seen near shore in Mason, Thurston,
Pierce, or even King County; but in Clallam, Jefferson, San Juan, and
the other counties of the Northwest, one has no difficulty in
recognizing the dwarf race. Not only are these Crows much smaller in
point of size, but the voice is weaker, flatter, and more hoarse, as tho
affected by an ever-present fog. So marked is this vocal change, that
one may note the difference between birds seen along shore in Pierce
County and those which frequent the uplands. However,—and this caution
must be noted—the upland birds do visit the shore on occasion; and the
regular shore dwellers are by no means confined thereto, as are the more
typical birds found further north.
The early observers were feeling for these differences, and if Nature
did not afford sufficient ground for easy discrimination, imagination
could supply the details. The following paragraph from the much quoted
work[4] of John Keast Lord is interesting because deliciously untrue.
