                              THE BERNACLE GOOSE.
                               [Barnacle Goose.]


                            ANSER LEUCOPSIS, Bechst.

                       PLATE CCCLXXVIII.--MALE AND FEMALE.


     Several old gunners on the coast of Massachusetts and Maine, who were
Englishmen by birth, assured me that they had killed Bernacles there, and that
these birds brought a higher price in the markets than the Common Brent Geese.
The Prince of Musignano states in his Synopsis that they are very rare and
accidental in the United States, and Mr. NUTTALL says that they are "mere
stragglers" there.  For my part, I acknowledge that I never met with one of
them, either along the coast or in the interior, although I have seen beautiful
mounted specimens in various parts.  Being neither anxious to add to our Fauna,
nor willing unnecessarily to detract from it, I have figured a pair of these
birds, with the hope that ere long, the assertion of the gunners, and those
of the authors above mentioned, may be abundantly verified by the slaughter of
many Geese.  In the mean time I must further confess my ignorance of the habits
of the Bernacle.
     Mr. SELBY thus speaks of it in the second volume of his
Illustrations:--"The Bernicle is amongst the number of our winter visitants,
annually resorting in vast numbers, upon the approach of autumn, to the western
shores of Britain, and to the north of Ireland.  Upon the Lancashire coast, the
Solway Frith, &c. it is very abundant; frequenting the marshy grounds that are
occasionally covered by the spring-tides, and such sands as produce the
sea-grasses and plants upon which it feeds.  Upon the eastern and southern
shores of Britain it is of rare occurrence, its place being supplied by its
nearly allied congener, the Brent Goose (Anser Brenta); which again is as rarely
seen upon the opposite coast of the island.  Like the rest of the genus, the
Bernicle is a very wary bird, and can only be approached by the most cautions
manoeuvers.  It is sometimes shot by moonlight, when it comes on the sands to
feed, by persons couched on the ground, or from behind any occasional shelter in
such places as the flocks are known to frequent.  Its flesh is sweet and tender,
and highly esteemed for the table.  Upon the approach of spring it leaves our
shores for more northern countries, and by the middle of March the whole have
retired."  It is known to breed in Iceland, Spitzbergen, Greenland, &c. as well
as in Lapland, the northern parts of Russia, and northern Asia.  It also
inhabits Hudson's Bay and other polar districts of the American continent.
During its equatorial or winter migration, it is abundant in Holland, France,
and parts of Germany.
     The eggs, which I describe from specimens deposited in the rich Museum of
the University of Edinburgh, measure two inches and seven-eighths by one inch
and seven-eighths, and are of a uniform yellowish-cream colour.
     I have represented an adult male in spring, and a female of the preceding
year.

conical, slightly depressed towards the end, narrowed and rounded at the tip.
Upper mandible with the dorsal line sloping, the ridge broad and flattened, the
sides sloping, the edges soft and obtuse, the oblique marginal lamellae short,
transverse, about thirty on each side, besides minute anterior ones; the unguis
roundish, convex, striato-denticulate on the inner edge.  Nasal groove

the body; legs bare a little above the tibio-tarsal joint.  Tarsus short, a
little compressed, covered all round with angular reticulated scales, which are
smaller behind.  Hind toe extremely small, with a very narrow membrane; third
toe longest, fourth a little shorter, but longer than second; all the toes
reticulated above at the base, but with narrow transverse scutella towards the
end; the three anterior connected by a reticulated membrane, the outer; with a

curving below the lower eyelid, and running along the upper, brownish-black.
Neck all round glossy black, of which colour are the anterior or dorsal
feathers, the scapulars, and the wing-coverts, towards their extremities, while
their bases are ash-grey, and their terminal margins white.  The shorter
feathers on the middle of the back are similar; those on the rump and the
tail-feathers deep black.  The quills are greyish-black, darker towards the
tips, the outer webs more or less tinged with ash-grey.  The breast, sides, and
abdomen greyish-white, the upper feathers of the sides with more grey; the upper
