[Illustration: _Hirundo horreorum._]

SP. CHAR. Tail very deeply forked; outer feathers several inches

longer than the inner, very narrow towards the end. Above glossy blue,

with concealed white in the middle of the back. Throat chestnut; rest

of lower part reddish-white, not conspicuously different. A steel-blue

collar on the upper part of the breast, interrupted in the middle.

Tail-feathers with a white spot near the middle, on the inner web.

Female with the outer tail-feather not quite so long. Length, 6.90

inches; wing, 5.00; tail, 4.50.

HAB. Whole of the United States; north to Fort Rae, Slave Lake;

Greenland; south in winter to Central America and West Indies; Panama

(LAWR.); Plateau of Mexico (breeds, SUMICHRAST); Veragua, Chiriqui

(SALVIN). Not found at Cape St. Lucas. South America?

In young birds, the frontal chestnut band is maller and less distinct.

It is still a question whether a South American resident species (_H.

erythrogaster_) is identical or not. The only two specimens of the

latter (21,007 and 21,008, Vermejo, Feb., 1860; C. Wood) have a very

much less violaceous upper plumage than North American examples, the

blue above having even a greenish tinge. They are moulting,

unfortunately, so that they cannot be satisfactorily compared; except

in the respect pointed out, however, they appear to be identical with

North American examples.

The European _H. rustica_ is perfectly distinct, though closely

allied. It differs essentially from the American _H. horreorum_ in

much longer outer tail-feathers, and in having a very broad,

continuous collar of steel-blue across the jugulum, entirely isolating

the chestnut of the throat; the abdomen appears to be much more

whitish than in the American species.

Many specimens of _H. horreorum_ show a continuous collar, but then

the two lateral crescents are but just barely connected. In No. 2,191

♀, Carlisle, Penn., May, there is an indication of as broad a collar

as in the European species; but the area, though sharply bounded, is

not uniformly black, being much mixed centrally with light rufous.

Specimens of _H. horreorum_ from both coasts of North America appear

to be perfectly identical.

HABITS. No one of all our North American birds is more widely

diffused, more generally abundant, wherever found, or better known,

than the graceful and familiar Barn Swallow. And no one is more

universally or more deservedly a favorite. Found throughout North

America from Florida to Greenland and from ocean to ocean, and

breeding nearly throughout the same wide extent, its distribution is

universal. Venturing with a confiding trust into our crowded cities,

and building their elaborate nests in the porches of the dwellings, as

well as entering in greater numbers the barns and farm-buildings of

the agriculturists and placing themselves under the protection of man,

they rarely fail to win for themselves the interest and good-will they

so well deserve. Innocent and blameless in their lives, there is no

evil blended with the many benefits they confer on man. They are his

ever-constant benefactor and friend, and are never known, even

indirectly, to do him any injury. For their daily food, and for that

of their offspring, they destroy the insects that annoy his cattle,

injure his fruit-trees, sting his fruit, or molest his person. Social,

affectionate, and kind in their intercourse with each other; faithful

and devoted in the discharge of their conjugal and parental duties;

exemplary, watchful, and tender alike to their own family and to all

their race; sympathizing and benevolent when their fellows are in any

trouble,—these lovely and beautiful birds are bright examples to all,

in their blameless and useful lives.

This Swallow passes the winter months in Central and South America as

far south as Brazil and Paraguay, and the West Indies, and is found

throughout the year in the Plateau of Mexico. It appears in the

Southern States in March, and in the Central States early in April. In

the latter part of this month it reaches New York and New England,

becoming abundant near Boston about the first of May. Sir John

Richardson found them breeding as far north as latitude 67° 30′. They

reached Fort Chippewyan, latitude 57°, as early as the 15th of May,

taking possession of their nests. It has been found throughout Canada

and in all the British Provinces, has been met with in New Mexico, and

is common in certain portions of Texas and the Indian Territory. Dr.

Cooper states it to be less abundant on the Pacific than on the

Eastern coast,—a fact attributable to the lack of suitable places in

which to build. As settlements have multiplied, these birds have

gradually increased about farms near the coast. In the wild districts

they build in the caves that abound in the bluffs along the sea-shore

from San Domingo to Columbia River. Dr. Suckley found them also

moderately abundant about the basaltic cliffs, near Fort Dalles,

Oregon. They are much more abundant about the coast than farther

inland.

Mr. Ridgway found this Swallow a very common species in all the rocky

localities in the vicinity of water, but not so numerous as the

_lunifrons_.

In May it was particularly numerous in the neighborhood of Pyramid

Lake, where its nests were built among the “tufa domes,” attached to

the roofs of the caves. It was seldom that more than one or two pairs

were found together.

In July he found a nest that contained young, in a cave among the

limestone cliffs of the cañons of the East Humboldt Mountains, at an

altitude of about eight thousand feet. Many of their nests were found

in May, in the caves of the tufa rocks, on the shores of Pyramid Lake,

as well as on the islands in the lake.

Mr. Hepburn writes that he found this Swallow widely diffused along

the Pacific coast, as far to the north as Sitka. In California he

found it very local, common near the coast, rare inland. Its earliest

appearance is March 26, the great bulk leave in August, and the last

stragglers are gone before the last of September. They breed in caves

and crevices of rocks, and also under the sides of the wooden bridges

that span the gullies at San Francisco. Two broods are hatched in a

year. The earliest egg was found on the 30th of April, but they are

usually a fortnight later. The second laying is about the first of

July, and no eggs were found later than the 4th of August. It is at

all times quite common to find nests with fresh eggs close to others

with half-grown young.

Mr. J. K. Lord publishes an interesting account of a visit made by a

solitary pair of Barn Swallows to his party when encamped at

Schyakwateen, in British Columbia. A small shanty, loosely built of

poles, and tightly roofed, was in constant use as a blacksmith’s shop.

Early one summer morning late in June, a pair of Swallows perched on

the roof of this shed, without exhibiting the slightest fear of the

noise made by the bellows or the showers of sparks that flew all

around. Presently they entered the house and carefully examined the

roof and its supporting poles, twittering to each other all the while

in the most excited manner. At length the important question appeared

to be settled, and the following day they commenced building on one of

the poles immediately over the anvil. Though the hammer was constantly

passing close to their structure, these birds kept steadily at their

work. In about three days the rough outline of the nest had been

constructed. Curious to see from whence they procured their materials,

Mr. Lord tracked them to the stream where, on its edge, they worked up

the clay and fine sand into a kind of mortar with their beaks. They

worked incessantly, and in a few days their nest was finished, the mud

walls having finally been warmly lined with soft dry grasses and the

feathers and down of ducks and geese. This trustful pair seemed to

know no fear. The narrator often stood on a log to watch them, with

his face so near that their feathers frequently brushed against it as

they toiled at their work. Soon the nest was completed. Five eggs were

laid, which were never left once uncovered until they were hatched,

the female sitting the greater part of the time. They were fed with

great assiduity by the parents, and grew rapidly. In leaving the nest,

two of the young birds fell to the ground, but were picked up by the

blacksmith, and placed with the others on their roosting-place. A few

days’ training taught them the use of their wings, and they soon after

took their departure.

Professor Reinhardt records its occurrence in Greenland, at

Fiskenæsset and at Nenontalik.

The natural breeding-places of these birds, before the settlement of

the country, were caves, overhanging rocky cliffs, and similar

localities. Swallow Cave, at Nahant, was once a favorite place of

resort, and in the unsettled portions of the country they are only

found in such situations. As the country is settled they forsake these

places for the buildings of the farm, and their numbers rapidly

increase. In the fur countries and in all the Pacific coast, they

still breed in and inhabit caves, chiefly among limestone rocks.

Where the opportunity offers, they prefer to place their nests on the

horizontal rafters of barns. Built in this situation, the nests have

an average height and a breadth of about five inches. The cavity is

two inches deep and three inches wide, at the rim. The nests are

constructed of distinct layers of mud, from ten to twelve in number,

and each separated by strata of fine dry grasses. These layers are

each made up of small pellets of mud, that have been worked over by

the birds and placed one by one in juxtaposition until each layer is

complete. These mud walls are an inch in thickness. When they are

completed, they are warmly stuffed with fine soft grasses and lined

with downy feathers. When built against the side of a house, a strong

foundation of mud is first constructed, upon which the nest is

erected. In this case the nest is much more elongate in shape and more

strongly made.

A striking peculiarity of these nests is frequently an extra platform,

built against, but distinct from the nest itself, designed as a

roosting-place for the parents, used by one during incubation at night

or when not engaged in procuring food, and by both when the young are

large enough to occupy the whole nest. One of these I found to be a

separate structure from the nest, but of similar materials, three

inches in length and one and a half in breadth. This nest had been for

several years occupied by the same pair, though none of their

offspring ever returned to the same roof to breed in their turn. Yet

in some instances as many as fifty pairs have been known to occupy the

rafters of the same barn.

In one instance Mr. Allen has known a pair of these Swallows to take

possession of the nest of a pair of Cliff Swallows, placed under the

eaves of a barn, driving off the rightful owners. The next year they

built a nest in the same place, the old one having fallen down. But

such instances are rare, and the attempt is often a failure.

The wonderful activity of this bird, its rapidity and powers of

flight, are too striking a peculiarity of this species not to be

mentioned. During their stay with us, from May to September, from morn

to night they seem to be ever in motion, especially so before

incubation, or after their young have flown. The rapidity of their

tortuous evolutions, their intricate, involved, and repeated zigzag

flights, are altogether indescribable, and must be witnessed to be

appreciated. Wilson estimated that these birds fly at the rate of a

mile a minute, but any one who has witnessed the ease and celerity

with which they seem to delight in overtaking, passing, and repassing

a train of cars moving at the rate of thirty miles an hour must

realize that this estimate is far from doing full justice to their

real speed.

The song of this Swallow, especially when on the wing, is very

pleasing and sprightly. It is a succession of twittering notes uttered

with great rapidity and animation. When alighted, their notes are

delivered more slowly and with much less animation.

The attention of these birds to each other when sitting upon the nest,

and to their young when hatched, is unremitting. The estimated numbers

of small insects they collect for their own consumption and that of

their nestlings is almost incredible. When the young are old enough to

leave their nests the manœuvres of the parents to draw them out, and

their assistance to them when practising their first short flights,

are among the most curious and interesting scenes one can witness in

his ornithological experiences; but space would fail me were I to

attempt their details.

The number of the young is from four to six, and there are often two

broods in a season. As soon as the second brood can fly, or early in

September, they all prepare to leave. They usually collect in flocks

of from one to several hundred, and depart within a few days of their

first assembling. Large flocks pass along the coast of Massachusetts,

from the north and east, early in September, often uniting as they

meet, and passing rapidly on.

Their eggs have a ground-color of clear white, with a roseate tint

when unblown. They are marked with spots of reddish and

purplish-brown, varying in size and number, and chiefly at the larger

end. They are smaller and more elongate than those of the _lunifrons_,

and the markings are usually finer. Their greatest length is .94 of an

inch, their least .75, and their mean .78. Their mean breadth is .56

of an inch, the greatest .62, and the least .50.
