Life histories of North American shore birds, Part 1 (of 2)
Bent, Arthur Cleveland
Birds -- Behavior; Shore birds -- North America
Entire upper parts richly varied, deep rufous and black, dotted
here and there with white; a buffy white streak passes from the
forehead over the eye; below this is a dark-brown streak covering
the lores to the eye; from the base of the lower mandible another
white streak passes below the eye and one also from the chin (which
is buffy white) along the side of the head to the nape; underparts
dark-reddish brown, slightly varied with blackish brown; bill and
legs much developed.
For descriptions of subsequent plumages and molts the reader is referred
to "A Practical Handbook of British Birds," edited by H. F. Witherby
(1920).
_Food._--Probably consists mainly of worms, with a considerable mixture
of insects and some vegetable matter (seeds, etc.). Naumann (1887)
remarks that he has several times found grass seeds in stomachs and
believes that vegetable matter is taken as well as insects and worms.
Newstead records Coleoptera (3 cases), Mollusca (_Tellina_ and _Helix_,
2 cases), vegetable matter (grass, etc.), sand, and pebbles. Cordeaux
found fragments of fresh-water shells and a few bivalves (_Pisidia_),
while Saxby met with plant fibers and mud.
_Behavior and voice._--The jack snipe is an extremely silent bird, and
to a great extent, solitary, outside the breeding season. The noises
made during the nuptial flight have already been dealt with, but it is
characteristic of the species that when flushed, unlike the common
snipe, it nearly always rises in silence. Naumann, however, writes that
on rare occasions, generally toward evening, a weak, high-pitched note
may be uttered, like "_Kitz_" or "_Kutz_," which he compares to a bat's
squeak. One may, however, put up twenty birds one after another without
hearing anything, though very rarely a single "_ahtch_" is uttered, much
more softly than the corresponding note of the common snipe. On being
flushed it dashes off quickly with unsteady flight, but pitches again
before rising to any height, and, except on migration or on its breeding
ground, usually flies low.
_Field marks._--Its solitary habits and small size are the best field
characters, combined with the fact that it is not shy and usually rises
at very short range, so that one gets a good view of it before it
pitches again at no great distance, where it can be flushed again. The
almost invariable absence of any note on rising is very characteristic.
