The genus _Gallinago_ differs from the above in having longitudinal stripes
on the head. _G. caelestis_, the Common or Full Snipe,[190] breeds in
Northern and Central Europe and Asia, and even in North Italy; it is
recorded from Greenland and the Bermudas, and migrates to the Atlantic
Islands, the Gambia, the Upper Nile, and the Indian Region. Its brown,
black, and buff plumage, with three buff streaks on the head, is
well-known, while there are normally fourteen rectrices. _G. sabinii_ is
merely a dark form. As regards its autumnal influx and food the Snipe
resembles the Woodcock, but the cry of "scape-scape" and twisting
{291}flight on rising, remain to be mentioned, while the alternate zig-zag
rise and fall of the bird when circling in the air near its nest, with the
curious drumming or bleating noise produced at each descent must not be
omitted. The method of production of this sound is still uncertain, but is
either due to the vibration of the wings, or more probably to that of the
webs of the outer rectrices. The slight nest is formed in a tuft of herbage
in some marshy place, the four pointed eggs being olive, with spots and
oblique blotches of brown. Snipe occasionally perch on trees or squat upon
the ground until touched. The very similar _G. delicata_ (_wilsoni_),
breeding northwards from the northern United States, and migrating to
northern South America, has usually sixteen rectrices, as have the six
following species. _G. major_, the Double or Solitary Snipe, nests as far
south in Europe as Holland and Poland, and reaches the Yenesei; it is known
from the Tian-Shan Mountains, Turkestan, and Persia, and winters even in
Natal and Damara-Land, visiting Britain annually on passage. It rises
silently and heavily when flushed, is to some extent nocturnal, and drums
when on the ground. The three outer tail-feathers are chiefly white.[191]
_G. frenata_, ranging from Argentina and Tarapacá to Venezuela and Guiana;
_G. nobilis_ of Colombia and Ecuador, _G. paraguaiae_, reaching from
Amazonia and Bolivia to the Falklands, _G. macrodactyla_ (_bernieri_) of
Madagascar, and _G. aequatorialis_ (_nigripennis_), of the Ethiopian Region
generally, conclude this section of the genus. _G. australis_ is similar to
our Snipe, but larger; it breeds in Japan, and migrates through Formosa to
Australia; _G. nemoricola_, the Wood-Snipe of the hills of India and Burma,
has the lower parts distinctly barred; _G. solitaria_, breeding at
considerable elevations from Turkestan to Assam and Japan, and wintering in
those countries and China, exhibits distinct white streaks above. In the
three last-named species the rectrices number about eighteen, in the next
six they may be as few as fourteen. South America furnishes five forms
somewhat like Woodcocks in their habits and eggs, namely, _G. gigantea_ of
Brazil and Paraguay, the largest of the Snipes; _G. undulata_ of Guiana;
_G. jamesoni_, ranging from Colombia to Bolivia; _G. imperialis_ of the
