_Plumages._--The young snipe in its dark and richly-colored natal down
is one of the handsomest of the young waders. The upper parts, including
the crown, back, wings, and thighs, are variegated or marbled with
velvety black, "bay," "chestnut," and "amber brown"; the down is mainly
black at the base and brown-tipped; the entire upper parts are spotted
with small round white spots at the tips of some of the down filaments,
producing a beautiful effect of color contrasts and a surprisingly
protective coloration. The head is distinctively marked with a white
spot on the forehead, a black crescent above it and a black triangle
below it, partially concealed by brown tips; there is a distinct black
loral stripe, extending faintly beyond the eye, and a less distinct
black malar stripe; between these two is a conspicuous, large, white,
cheek patch. The chin and upper throat are "light ochraceous buff";
below this on the lower throat is a large sooty-black area, partially
concealed by brown tips, these "tawny" brown tips predominating on the
breast and flanks, and shading off to "pale pinkish cinnamon" on the
belly.
The juvenal plumage appears first on the back and scapulars, then on the
breast and wing coverts. A bird in my collection, about half grown has
the above parts well feathered and the remiges one-third grown; but the
head and rump are still downy and the rectrices have not yet started.
The juvenal plumage is like the adult, except that the buff edgings of
the feathers on the sides of the back and the scapulars, forming the
stripes, are narrower and paler, sometimes almost white on the outer
webs. The body feathers and some of the scapulars and tertials are
molted during the fall, making the young bird almost indistinguishable
from the adult.
Both young birds and adults have a partial prenuptial molt in the late
winter and early spring, involving the contour feathers, wing coverts,
tertials, and the tail. Adults have a complete molt between July and
October. The spring and fall plumages are alike except that the fresh
fall plumage is somewhat more richly colored.
_Food._--The feeding habits of the Wilson snipe are much like those of
the woodcock, except that it often feeds in much wetter places and is
somewhat less nocturnal. Benjamin T. Gault (1902) discovered by
observation that snipe occasionally resort to open mud flats, unmindful
of the cover of darkness and that they feed at all hours of the day. He
describes their method of feeding as follows:
