Obs. As stated in the preceding pages, this bird much resembles, if it

is not identical with, the species known as _Bernicla Hutchinsii_, from

which the most essential distinctive character is the white ring around

the neck. If identical, we have, at any rate, the gratification of being

the first to represent that species, in mature plumage. At present we

regard it as a distinct, though nearly allied bird.

The date of the publication of Prof. Brandt’s first description we have

not succeeded in ascertaining, not having access to the Bulletin of the

Academy of St. Petersburg. The reference to the volume and page we copy

from his own citation, in his work above quoted, in which, however, the

date is not stated.

THALASSIDROMA FURCATA.—(Gmelin.)

The Gray Storm Petrel.

PLATE XLVI. Adults.

The little birds of the group to which that now before the reader

belongs, are known to seamen, wherever the English language is spoken,

as Storm Petrels, or “Mother Carey’s Chickens,” and have too, a

reputation, not without a tinge of superstition, of being the harbingers

of the storm and of maritime disaster.

Of the many birds adapted by their organization to a life of adventure

on the ocean or its tributaries, and of which in fact during a large

portion of their lives they are almost as much inhabitants as fishes,

the Albatrosses and the Storm Petrels, or Mother Carey’s Chickens,

venture the most boldly. The birds of both these genera, though one

contains the largest and the other the smallest of marine birds, are

alike in this particular character, and are also alike known as

inhabitants of shores very remote from each other, and as wanderers over

immense extents of the ocean.

Boldly directing their course far out on the sea, like their gigantic

relatives the Albatrosses, our present little birds are frequently to be

met with in nearly all latitudes usually traversed by navigators, and

are generally tempted to remain for a time in the wakes of vessels, and

about them, by the fragments of food to be gleaned from refuse thrown

overboard. Flitting as it were before the gale, with it, the appearance

of these birds may readily be coincident, or premonitory of its coming,

thus acquiring, and perhaps in some degree justly, the attributed

character of precursors.

Several species of these birds are found on the coasts of the United

States. The most abundant and best known is Wilson’s Storm Petrel

(_Thalassidroma Wilsonii_), a bird which is perhaps to be regarded as

more nearly cosmopolite than any other, so extensive are its wanderings

over the surface of the ocean. It is of common occurrence throughout the

whole extent of the eastern shores of the continent of America, and it

has been repeatedly noticed and captured at various points on the coasts

of Europe and Africa, thus demonstrating a range over nearly the entire

Atlantic Ocean. In the Pacific also it is well known, though it is not

so abundant. Mr. Gould gives it as a bird of Australia; and the

naturalists of the United States’ Exploring Expedition in the Vincennes

and Peacock, record its appearance at various other points in the

Pacific Ocean.

The Gray Petrel

Thalassidroma furcata (_Gmelin_)]

The histories of this, and of other American species of Storm Petrels,

are perhaps as well known as those of the sea-birds generally, and much

that is interesting may be found in the articles on them in the works of

our predecessors in American Ornithology; but we cannot allow the

present occasion to pass without availing ourselves of the kindness of

our friend, Charles Pickering, M. D., of Boston, one of the naturalists

attached to the Exploring Expedition, and justly ranked with the most

eminent of American Zoologists.

With his characteristic liberality, Dr. Pickering has placed at our

disposal much valuable information relative to birds observed during the

voyage of the Expedition, especially on the western coast of North

America, and in other localities of interest, with reference to American

species. From his manuscript we copy the following in relation to

Wilson’s Petrel, which occurs under date of October 24th, 1838, and from

the latitude and longitude given, the nearest land was the coast of

Africa:

“A stormy Petrel taken, which proved to be _Thalassidroma Wilsonii_, and

although this species and others of its genus have been constantly seen

during the voyage of the Expedition, this is the first specimen that has

been captured without having been injured, thus affording whatever

facilities can be obtained on shipboard for observing its manners.

“I was rather surprised to observe that this bird was not only entirely

incapable of perching, but even of standing upright like birds in

general, and as I have seen birds of this genus represented, unless by

the aid of its wings. In standing, or rather sitting, the whole of the

_tarsus_ (commonly mistaken for the leg) rests on the ground, and it

walks in the same awkward position, frequently being obliged to balance

itself with its wings. By a more powerful exertion of its wings,

however, it was enabled to run along on its toes in the same manner as

it does over the surface of the waves. The absence of a hind toe, the

nails being but slightly bent and flat, and perhaps I may add, its

evidently being unaccustomed to this description of locomotion, seemed

to be the causes of its helplessness on its feet.

“These birds have been numerous about us for some days past, and their

coursing over the water with flitting wings remind me of the actions of

butterflies about a pool. One of them was seen swimming, or at least

resting, on the surface. We have seen this species very frequently,

indeed almost daily, since leaving America, and scarcely any other

sea-birds, except in the immediate vicinity of the islands. It would

seem that it scarcely ever visits the land, except for the purposes of

incubation, and there can hardly be a better comment on its untiring

power of wing than the popular fable amongst seamen that it carries its

egg and hatches its young while sitting in the water. It does not sail

in the continued manner of the gulls and some other sea-birds, but moves

by rapidly flexing its wings something like a bat, and was continually

coursing around and in the wake of the vessel, generally in considerable

numbers, during much the greater part of the time that the Expedition

was in the Atlantic Ocean.”

The curious fact that this bird cannot stand upright we do not remember

ever before having seen noticed. Of the specimen alluded to, Dr.

Pickering gives notes of a minute and evidently very careful anatomical

examination, which the limits of our present article will not allow us

to insert. They are, however, confirmatory, in most respects, of the

account of the anatomy of this species, given by Mr. Audubon, in

Ornithological Biography, V., p. 645.

The bird before the reader in the present plate is an inhabitant of the

Northern Pacific Ocean, and is an interesting addition to the

ornithological fauna of the United States, made by the naturalists of

the Exploring Expedition, under command of Captain Charles Wilkes, to

which we have previously alluded. Though long known as a bird of the

coasts of Asiatic Russia and of Russian America, it had never before

been noticed on the more southern coast of Oregon, where it was found in

large numbers by the Expedition, and specimens then obtained are now in

the National Museum at Washington.

This bird was first noticed by the celebrated Pennant, in Arctic

Zoology, Vol. II., p. 255, who called it the “Fork-tailed Petrel.” An

accurate description is given by him, but no further account of it than

merely stating “taken among the ice between Asia and America.” On the

faith of this description, Gmelin, in _Systema Naturæ_, as cited below,

gave the scientific name. Subsequently, Pallas mentions it as an

inhabitant of the coasts of Unalaschka and of the Kurile Islands. It is

also mentioned in the Zoology of the Voyage of the Sulphur, (London,

1844,) and very handsomely figured from specimens obtained at Sitka in

Russian America.

To the journal of Dr. Pickering we have again to acknowledge our

obligations for a notice of this bird. First recording its occurrence on

the 26th of April, 1840, at sea, the distance from the coast of Oregon

being about 200 miles, he subsequently mentions it under date of 29th of

the same month, as follows:

“In sight of the coast of Oregon. Great numbers of the gray

_Thalassidroma_ are to-day flitting around and in the track of the

vessel, very actively engaged in searching for particles of food thrown

overboard. Generally, this bird reminds us of _T. Wilsonii_, but the

wings seem longer, and its movements appear to be more rapid, and in

fact more like that of the larger Petrels, (_Procellaria_.) It

occasionally sails in its flight, but for the greater part moves by very

rapidly flexing its wings in the same manner as the species mentioned.

“These birds proved not difficult to capture, and several specimens were

taken with a hook and line. They would dive a foot or two after the

bait, and made use of their wings in and under the water, from which

they apparently had not that difficulty in rising observable in the

Albatrosses. Though their powers of swimming seemed rather feeble, they

alighted in the water without hesitation. The dead body of one of their

companions being thrown overboard, they clustered around it with as much

avidity as around any other food.

“The specimens obtained agree generally in color of plumage, being

nearly a uniform pale gray, with the abdomen sometimes paler or nearly

white, and generally showing a lighter bar across the wing, when

expanded. Uttered a faint note when taken on board.”

At present we have no further information relating to this interesting

species.
