LEAST PETREL.--MOTHER CAREY'S CHICKEN.
[British Storm-Petrel.]
THALASSIDROMA PELAGICA, Linn.
[Hydrobates pelagicus.]
PLATE CCCCLXI.--MALE AND FEMALE.
In August 1830, being becalmed on the banks of Newfoundland, I obtained
several individuals of this species from a flock composed chiefly of
Thalassidroma Leachii, and Th. Wilsoni. Their smaller size, and the more rapid
motions of their wings, rendered them quite conspicuous, and suggested the idea
of their being a new species, although a closer inspection shewed them to belong
to the present. In their general manners, while feeding, floating on the water,
or rambling round the boat in which I went in pursuit of them, they did not
differ materially from the other species. Their flight, however, was more
hurried and irregular, and none of them uttered any note or cry, even when
wounded and captured. I have been assured that this bird breeds on the sandy
beaches of Sable Island on the coast of Nova Scotia; but not having had an
opportunity of visiting it, or any other breeding place, I here present you with
Mr. HEWITSON's observations on this subject.
"In an excursion," says this amiable and enterprising naturalist, "through
the Shetland Islands during the present summer, in search of rarities for this
work, (the British Oology,) I had the very great satisfaction of seeing and
taking many of these most interesting birds alive; they breed in great numbers
on several of the islands, principally upon Foula, the north of Hunst, and upon
Papa, and, Oxna, two small islands in the Bay of Scalloway; the last of these I
visited on the 31st of May in hopes of procuring their eggs (it being the season
in which most of the sea-birds begin to lay); but in this; I was disappointed;
the fishermen, who knew them well by the name of Swallows, assured me that my
search would be quite useless, that they had not yet "come up from sea," and so
it proved. Sixteen days after this (June 16th and three following days) I was
at Foula, but was alike unsuccessful, the birds had arrived at their breeding
places, but had not yet begun laying their eggs; numbers of them were sitting in
their holes, and were easily caught: one man brought me about a dozen tied up
in an old stocking, two of which I kept alive in my room for nearly three days,
and derived very great pleasure from their company; during the day they were
mostly inactive, and after pacing about the floor for a short time, poking their
head into every hole, they hid themselves between the feet of the table and the
wall; I could not prevail upon them to eat any thing, though I tried to tempt
them with fish and oil; their manner of walking is very light and pleasing, and
differing from that of every other bird which I have seen; they carry their body
so far forward and so nearly horizontal, as to give them the appearance of being
out of equilibrium. In the evening, toward sun-set, they left their hiding
places, and for hours afterwards, never ceased in their endeavours to regain
their liberty; flying round and round the room, or fluttering against the
windows; when flying, their length of wing, and white above the tail, gives them
a good deal the appearance of our House-Martin. I went so bed and watched them
in their noiseless flight, long ere I fell asleep, but in the morning they had
disappeared; one had fortunately make its escape through a broken pane in the
window which a towel should have occupied, the other had fallen into a basin,
full of the yolks of eggs which I had been blowing, and was drowned. I
regretted much the fate of a being so interesting, by its very remarkable,
wandering, solitary, and harmless life. Before leaving Shetland I again visited
the island of Oxna, and though so late as the 30th of June, they were only just
beginning to lay their eggs. In Foula they breed in the holes in the cliff, at
a great height above the sea; but here under stones which form the beach, at a
depth of three or four feet, or more, according to that of the stones; as they
go down to the earth, beneath them, on which to lay their eggs. In walking over
the surface, I could hear them, very distinctly, singing in a sort of warbling
chatter, a good deal like Swallows when fluttering above our chimneys, but
harsher; and in this way, by listening attentively, was guided to their retreat,
and, after throwing out stones as large as I could lift on all sides of me,
seldom failed in capturing two or three seated on their nests, either under the
lowest stone or between two of them. The nests, though of much the same
materials as the ground on which they were placed, seem to have been made with
care; they were of small bits of stalks of plants, and pieces of hard dry earth.
Like the rest of the genus, the Stormy Petrel lays invariably one egg only.
During the day-time they remain within their holes; and though the fishermen are
constantly passing over their heads, (the beach under which they breed being
appropriated for the drying of fish,) they are then seldom heard, but toward
night become extremely querulous; and when most other birds are gone to rest,
issue forth in great numbers, spreading themselves far over the surface of the
sea. The fishermen then meet them very numerously; and though they have not
previously seen one, are sure to be surrounded by them upon throwing pieces of
fish overboard."
The egg measures one inch and an eighth in length, six and a half eighths
in breadth, is nearly equally rounded at both ends, rather thick-shelled, and
pure white, but generally with numerous minute dots of dull red at the larger
end, sometimes forming a circular band.

American coast.
