robust than most of our shore birds. Adults in summer, 
mixed brownish and gray, above, and uniform reddish- 
brown below. - In winter, plain gray above and white 
below; young similar but with feathers on the back 
. edged with white. It is an abundant species on the 
' Atlantic coast during migrations, and is known by vari- 
cus names such as Red-breasted Sandpiper and Robin 
Snipe, when in summer dress, and as Gray-back when 
in winter plumage. It is usually found on the ocean 
beach, where it follows the waves as they recede, pick- 
ing up numerous insects left there, and retreating be- 
fore the next wave. 
Notes.—An ordinary Sandpiper whistle. 
Nest.—Not positively known, but a supposed egg 
obtained by Lieutenant Greely in the vicinity of Fort 
Conger was pea-green in color, with small brown spots.
