DESCRIPTION AND TECHNICAL OBSERVATIONS.

Genus Saxicola. Bechstein, Ornithologisches Taschenbuch, p. 216.

(1802.)

Bill straight, with the culmen distinct and somewhat ascending into the

feathers of the forehead; a few short and weak bristles at the base of

the upper mandible, which is rather wide; wing rather long; first quill

spurious, third and fourth longest, and nearly equal; tail moderate,

wide, truncate; legs long, rather slender. General form adapted to

living on the ground.

Saxicola œnanthoides. Vigors, Zool. Voy. Blossom, Ornithology, p. 19.

(1839.)

Form. Rather larger than _Saxicola œnanthe_, but very similar to that

species in form and general characters and appearance; wing long; second

primary longest; tail moderate or rather short; legs, especially the

tarsi, long; bill moderate, rather wide at base.

Dimensions. Total length of skin, about 6½ inches; wing, 4⅛; tail, 3;

tarsus, 1¼ inches.

Colors. Narrow line through the eye, enlarging on the ears, black, which

is the color also of the wings; forehead ashy white, fading into the

cinerous of the head above; back cinerous; upper coverts of the tail

white; under parts white, tinged with pale fulvous, darker on the

breast; two middle feathers of the tail white at base; terminal

two-thirds of their length black; other feathers of the tail white,

tipped with black; bill and legs dark.

Hab. Northern America, Nova Scotia, Oregon. Spec. in Mus. Acad.,

Philadelphia.

Obs. We are not without doubts that the bird now before us is really

distinct from _Saxicola œnanthe_ of Europe, but having unfortunately a

single specimen only, we cannot make an examination or comparison in all

respects satisfactory. Our specimen is uniformly larger than either of

the numerous specimens of the European species in the collection of the

Philadelphia Academy, and is, as an especial character, longer in the

tarsi. Its measurements do not, however, correspond with those given in

the original description in Voy. Blossom; but it is expressly stated

that the specimens described were in bad condition, and may not be

entirely reliable. It is, at any rate, very closely allied to the

European species that we have just mentioned.

With special reference to the present bird, we shall look with much

interest for the results of future zoological investigations in the

northwestern territories of the United States. There is at the present

time no field more inviting to the American naturalist. While much has

been done in California, New Mexico, and Texas, the extensive regions

which we have above designated have scarcely been entered upon, and will

yet contribute much to the fauna of our country.

PLATE XXXV. Adult Male.

Those birds whose homes are the sea-coasts and islands, and whose lives

are spent in gleaning a subsistence amongst the billows or by the shores

of the ocean, have always been objects of interest both to the

naturalist and the general observer. Idly reposing on the rocky crag or

the sand-bank, or boldly sweeping the surface of the waters alike in the

calm and amidst the fury of the tempest, few having the opportunity have

failed to mark the sea-birds as a feature in the wild scenery peculiar

to the localities for which they are fitted by nature, and perhaps to

associate them with the adventurous character of our useful fellow-men

whose profession it is, in the beautiful language of the liturgy, to “go

down upon the deep.”

The large majority of the many birds that derive their subsistence from

the productions of the Ocean, live habitually on its shores, or venture

only short and easily-regainable distances from the land. This is the

case with the numerous genera comprising the Ducks, Swans, and Geese, as

well as the Pelicans, Cormorants, Penguins, and others. These, for the

greater part, frequent the margins of the bays and estuaries, and many

of them are almost as much birds of the land as of the sea. The Penguins

in fact having but rudiments of wings, and incapable of flight, are

necessarily restricted, though performing very remarkable migrations by

swimming. These extraordinary birds are peculiar to the southern

hemisphere, and have been met with amongst the ice and snow of the

highest latitudes which navigators have succeeded in reaching within the

Antarctic circle.

The bird which is the subject of our present article, is one of a group

of species which, possessing great powers of flight and swimming with

facility, do not content themselves with the vicinity of the coast, but

venture boldly out to sea. The largest and best known species, the

Wandering Albatross, has been observed by voyagers at a distance of two

thousand miles or upwards from land; and it is even supposed that it

performs a flight across the Atlantic from Cape Horn, or about its

latitude, to the Cape of Good Hope. The smaller species, of which the

present is one, do not venture on so long flights, but several voyagers

have recorded their having been seen at two to five hundred miles out at

sea.

On the sea-coast of America, on the Atlantic, the Albatrosses are found

inhabiting only a portion of the shores of the southern division of this

continent north of Cape Horn, but on the Pacific they are abundant

throughout the extent of the continent.

The black-footed Albatross

Diomedes nigripes (_Audubon_)]

The species that we present to the reader in the present plate, was

discovered on the coast of California by the late John K. Townsend, M.

D., and was first brought to notice by Mr. Audubon, in his

Ornithological Biography, V., p. 327, but the specimen appears to have

been accompanied by no notice of its history.

Since the period of its discovery, this bird has been again observed

only by Dr. Heermann, who has kindly furnished the following note from

his Journal:—

“The Black-footed Albatross abounds on the coast of California and

southward, as do several other species of this genus. It is commonly to

be seen skimming over the waves in its flight, and following in the wake

of vessels, to pick up the refuse scraps thrown overboard. With the

voracity characteristic of these birds, it seizes with little

discrimination on whatever is thrown into the water, and of this

propensity advantage may be taken by baiting a hook, by which, when

seized, the bird is easily secured. From the stern-ports of our ship,

during a voyage by sea to California, I have thus captured eight or ten

specimens of this and other species of this genus in a single morning.

All the species much resemble each other in habits, so far as my

observations extend.

“On the coast of California, I observed a White Albatross much smaller

than the large _Diomedea exulans_, but not having succeeded in procuring

it, I cannot designate the species.”

The small white species alluded to by Dr. Heermann, is probably new to

the ornithology of North America. Of the species known as inhabitants,

we may say of the Pacific ocean, several have not heretofore been

noticed by naturalists on the shores of the United States.
