_Eggs._--Four eggs is the normal number laid by the snipe; rarely five
eggs are laid. They are about ovate pyriform in shape and slightly
glossy. The ground colors vary from "buckthorn brown" or "Isabella
color" in the darkest types to "deep olive buff" or "dark olive buff" in
the lighter types, which are much commoner. As a rule the eggs are
boldly spotted and blotched, chiefly about the larger end; but often
they are spotted more or less evenly over the entire surface. The
markings are in dark shades of brown, "burnt umber," "bister," or "bone
brown." Often there are splashes or scrawls of brownish black, or black,
at the larger end. "Snuff brown," "vinaceous drab," or "brownish drab"
under spots or blotches often occur. The measurements of 57 eggs average
38.6 by 28.1 millimeters; the eggs showing the four extremes measure
=42.4= by 29.5, =36.1= by =29.9=, and 37.5 by =25.5= millimeters.
_Young._--The period of incubation is from 18 to 20 days, and it is
shared by both sexes. Mr. Philipp (1925) says that three birds taken
from the nest were all males. The young leave the nest soon after they
are hatched, and wander about in the long grass, where their concealing
coloration makes them very hard to find. One day, while watching snipe
with J. R. Whitaker on a large marsh near the mouth of Sandy River in
Newfoundland, I saw a snipe several times go down into the grass at a
certain place. Thinking to find a nest there I made a careful search,
and finally found one small downy young; but not another one could I
find in a long hunt. This moist meadow full of grassy hummocks is a
great breeding place for snipe. Here we frequently saw snipe sitting in
trees, bushes, or on telegraph poles, uttering their loud _kep kep kep_
notes of protest. On the girders of a steel bridge that spans the river
at this point Mr. Whitaker has seen as many as five snipe perched at one
time.
Mr. Sutton (1923) describes the behavior of an anxious mother as
follows:
The mother's antics so claimed my attention that I did not keep
close enough watch of the young, and eventually was unable to find
them. I hesitated to tramp about much at the time for fear of
stepping upon them. The mother bird grunted and clucked incessantly
and fell upon her side uttering weird cries, and beating her wings
pitiably. At times she would dart into the air and circle about in
great haste, very close to me and alight in the tall grass, whence
she would run gracefully away until she was again plainly in view.
As she ran about her head was held rather stiffly, and it seemed
that moving it from side to side much caused her inconvenience. In
fact once or twice a definite impression was given that she was
carrying something in her mouth, her head was held at such a
strained angle.
