Distribution. Breeds in Arctic Siberia. Of only casual occurrence in eastern Canada. 
More records from the Atlantic coast than inland, though there is one from lake Ontario. 
An Old World form occasionally seen in the New World. Said to 
resemble the Red-back in habit, but too scarce in eastern Canada to be 
looked for asa regular visitor. Any record of this species should be founded 
on definite specimens and subjected to a rigid scrutiny. 
246. Semipalmated Sandpiper. BLACK-LEGGED PEEP. FR.—LA MAUBECHE SEMI- 
PALMEE. Freunetes pusillus. L, 6-30. Upper parts, including crown, dark brown 
edged with light ochraceous or buffy; all white below, with vague band of slightly darker 
across the chest with obscure streakings and spots. 
Distinctions. Very similar in size and coloration to the Least Sandpiper, from which 
it cannot always be distinguished except by close examination. The toes, however, have 
small webs between their bases, giving the bird the name Semipalmated. 
Field Marks. Differentiated from the Least Sandpiper by its slightly larger size, 
purer grey back, and whiter, more clearly lined breast. Legs and feet are black instead 
of dark olive green. 
Distribution. Breeds along the eastern Arctic coast south to southern Labrador. 
Common in migration throughout eastern Canada. 
Very similar in habit as well as appearance to the Least Sandpiper, 
page 96. The Western Sandpiper Hreunetes maurz is a closely allied form 
that may be only a subspecies of the Semipalmated Sandpiper. It is 
distinguished by a slightly longer bill and a larger amount of red on the 
back, especially on the hindhead. Its occurrence in the Great Lakes region 
is very doubtful. ~ 
248. Sanderling. FR—LA SANDERLING. Calidris leucophea. L, 8. In spring— 
upperparts, including crown, dark brown variegated with much light rusty ochre or white, 
or both. Below, white. Throat, neck, and upper breast overwashed with more or Jess 
reddish-ochre and spotted with brown. The details of these colourings are exceedingly 
variable. The back may show enough of the various colours to make it either generally 
greyish, ochraceous, or rusty, and the coloured and spotted throat may be nearly immacu- 
lately white. The autumn bird is similar without much buffy or any reddish or ochra- 
ceous tint, it is pure white below and in front, and often predominantly grey to light 
ashy above. 
Distinctions. From traces to strong washes of rusty on neck and around head in the 
spring and the general whiteness in autumn. The Sanderling can be told from all other 
Sandpipers by having three toes instead of four. : 
Field Marks. Rufous suffusion about the head in some spring birds, general con- 
trasting black and white appearance on the wing, and line of white along the bases of 
flight feathers in all plumages. The pure white breast in autumn is also characteristic. 
Distribution. Breeds on the islands of the Arctic west to Alaska. A common migrant 
on sandy shores throughout eastern Canada. 
A bird of sandy shores, seldom frequenting mud flats. One of the most 
beautiful and interesting of the small Shore Birds. It haunts the edge of 
the water, following each retreating wave, and rapidly running back again 
before the wave’s return, threatened every moment to be engulfed in the 
surf but always just escaping. As the birds fly out over the blue water, the 
sun shining on their glistening plumage, they are a beautiful sight; at one 
moment turning their daintily coloured black and white backs and the next, 
as though moved by a single impulse, banking on a wide wheel and showing 
the pure glistening white of their underparts. 
249. Marbled Godwit. FR.—LA BARGE MARBREE. Limosa fedoa. 1,18. <A very 
large Shore Bird; a general light buff, faintly pinkish shade all over, except throat which 
may be white. Back, hind-neck to crown, variegated with dark brown and light tints and 
the breast and flanks more or less barred with fine lines of the same dark colour.
