LIMNODROMUS GRISEUS SCOLOPACEUS (Say)
LONG-BILLED DOWITCHER
HABITS
This is supposed to be a western form of the species, characterized by
an average larger size, a decidedly longer bill, and more uniformly
rufous under parts in the adult spring plumage. It was first described
and long regarded as a distinct species, but later developments have
shown intergradation and it has been reduced to sub-specific rank. The
above characters seem to hold good in all specimens collected on their
breeding grounds in Alaska and northwestern Mackenzie; and these
characters are distinctive and well marked. But in immature and winter
plumages the form can be recognized only by size; and, as the
measurements of the two forms overlap and intergrade, only the extremes
can be positively named. The matter is further complicated by the fact
that the migration and winter ranges of the two forms overlap. This
form, _scolopaceus_, is by no means rare on the Atlantic coast, and
_griseus_ occurs regularly on the Pacific coast; intermediates are most
abundant in the central valleys, but occur on both coasts.
_Spring._--The long-billed dowitcher is a rather early spring migrant;
the migration starts in March; the main flight through the United States
is in April; and it reaches its northern breeding grounds in May. Dr. E.
W. Nelson (1887) says of its arrival in northern Alaska:
