Part 16

This night song is rarely heard except in the months of May and June.

THE LESSER WHITETHROAT SYLVIA CURRÚCA

Head and lore dark ash-grey; rest of the upper parts greyish ash, tinged with brown; wings brown, edged with ash-grey; tail dusky, outer feather as in the last, the two next tipped with white; lower parts pure silvery white; feet deep lead colour. Length five inches and a quarter. Eggs greenish white, spotted and speckled, especially at the larger end, with ash and brown.

Gilbert White in his charming history says, "A rare, and I think a new little bird frequents my garden, which I have very great reason to think is the Pettichaps; it is common in some parts of the kingdom; and I have received formerly dead specimens from Gibraltar. This bird much resembles the Whitethroat, but has a more white, or rather silvery breast and belly; is restless and active, like the Willow-wrens, and hops from bough to bough, examining every part for food; it also runs up the stems of the crown-imperials, and, putting its head into the bells of those flowers, sips the liquor which stands in the nectarium of each petal. Sometimes it feeds on the ground like the Hedge-Sparrow, by hopping about on the grass plots and mown walks." The little bird of which the amiable naturalist gives so interesting a description, was, there is little doubt, that which is now called the Lesser Whitethroat, then a 'new bird', inasmuch as it had not been made a distinct species, and necessarily a 'rare bird', not because a few only visited Britain, but because, until his time set the example, competent observers of birds were rare. It differs externally from the preceding, in its smaller size, and the darker colour of its beak, upper plumage, and feet, and resembles it closely in its habits, though I have never observed that it indulges in the eccentric perpendicular flights, which have gained for its congener, the Greater Whitethroat, the quaint sobriquet of 'singing skyrocket.' It feeds, too, on insects, and is not found wanting when raspberries and cherries are ripe. But no matter what number of these it consumes, it ought with its companions to be welcomed by the gardener as one of his most valuable friends. For it should be borne in mind, that these birds, by consuming a portion of a crop of ripe fruit, do not at all injure the trees, but that the countless aphides and caterpillars which they devoured at an earlier period of the year, would, if they had been allowed to remain, have feasted on the leaves and young shoots, and so not only have imperilled the coming crop, but damaged the tree so materially as to impair its fertility for some time to come. Those birds, therefore, which in spring feed on insects and nourish their young on the same diet, may be considered as necessary to protect from injury the trees which are destined to supply them with support when insect food becomes scarce. Consider what would be the result if the proper food of birds were leaves, or if insects were permitted to devour the foliage unchecked! our woods would be leafless, our gardens would become deserts.

THE GARDEN WARBLER SYLVIA HORTENSIS

Upper parts greyish brown, slightly tinged with olive; orbits white; below the ear a patch of ash-grey; throat dull white; breast and flanks grey, tinged with rust colour; rest of the under parts dull white. Length five inches and three-quarters; breadth eight and a half. Eggs greenish white, speckled with two shades of greenish brown.

Though tolerably well dispersed throughout England, this bird is by no means so abundant as the Blackcap, which it resembles in size and habits, but it arrives later, coming early in May. It is very local. Its song is little if at all inferior to that of the bird just named, and it is far from improbable that some of the sweet strains for which the Blackcap gets credit, particularly late in the summer, may be produced by the Garden Warbler; I have heard its song so late as the fifth of October. By some authors it is called the Greater Pettychaps, by others the Fauvette, which latter name is by some French ornithologists applied to the group containing this bird and several allied species. Its nest and eggs are so like those of the Blackcap as to be discriminated with difficulty.

THE BLACKCAP SYLVIA ATRICAPILLA

Top and back of the head black, in the female chocolate colour; upper parts, wings, and tail ash-grey, slightly tinged with olive; neck light grey passing into greyish white; bill and feet black. Length five inches and a half; breadth eight and a half. Eggs pale greenish white, variously mottled with several shades of brown; sometimes pinkish, mottled with light purple, and speckled with dark purple.

Whatever difference of opinion there may be as to the character of the Nightingale's song--whether it partakes more of joyousness or of melancholy--the gladsomeness of the Blackcap's warble is beyond all dispute. Conceding to the Nightingale the first place among the warblers which visit England, we do not hesitate to claim the second for the Blackcap. Its song is inferior in power and compass to that of the bird of night, but there is about it a delicious eloquence which makes it irresistibly charming. White of Selborne describes it as "full, sweet, deep, loud and wild"; high but not unmerited praise. If there are no vocal efforts to astonish, there are no piteous wailings to distress, and though the bird retires to rest at a reasonable hour, it continues its song until a late period of the season, long after that of the Nightingale has degenerated to a croak. It has been compared to that of the Redbreast, but it is more mellow and flute-like; to that of the Thrush, but it is softer and of more compass; to that of the Lark, but it is more varied. A practised ear will confound it with neither of these, though, strange to say, many persons who have lived all their lives in the country and who take much interest in its pleasant sights and sounds, habitually confound it with the song of one or other of these birds, not knowing to whom they are indebted for one of the principal charms of their gardens. The Blackcap, like several other of the migratory warblers, returns again and again to its old haunts. For six successive years it has been known to build its nest in a bramble which hung down from a rock in a public garden; and for even a longer period my own garden has been annually visited by a pair who, from unfailingly resorting to the same bushes, must, I have little doubt, be the same pair, though I cannot say that I have found or even searched for their nest. On its first arrival in April, the Blackcap is in the habit of what bird-fanciers call 'recording'--that is, practising over its song in a low tone. During this season of rehearsal it does not care to be seen, but hides away in a thick bush. It is nevertheless by no means shy of being heard, as it will allow the listener to approach within a few yards of its hiding-place without stopping its song, and if disturbed will remove to a very little distance and recommence. After a few days it acquires its full powers of voice.

Its song is now remarkable among the full choir for sweetness, loudness, and long continuance. Its food at this time consists of aphides, caterpillars, and other small insects which infest roses and fruit-trees; it rarely captures flies on the wing or descends to feed on the ground. In June it begins to sing shorter strains, but with no diminished power. It may then be observed flying from branch to branch of an apple-tree, resting for a few seconds only in the same spot, and busily occupied in collecting grubs or aphides, then indulging in a short strain. In July, when the raspberries ripen, the Blackcap becomes chary of its song, and introduces its young brood to the choicest and juiciest fruit; in their attentions to which both old and young birds are exceedingly pertinacious, holding scarecrows in extreme contempt, and heeding clapping of hands or the discharge of a gun as little. The young of the first year resemble the adult female in having a chocolate-coloured crown. The song of the Blackcap may be heard occasionally late in the summer; in September or October both old and young take their departure, and the Redbreast is left without a rival to assert his superiority as a warbler, until the return of spring. The nest is usually placed in a hedge or low bush, a few feet from the ground, and is constructed of bents, and lined with fibrous roots and hair. The male bird assists the female in performing the office of incubation, and is said to relieve the monotony of his occupation by singing, thus often betraying a well-concealed nest.

THE DARTFORD WARBLER SYLVIA UNDATA

Upper parts blackish brown; under, purplish red; middle of the abdomen white; tail long, dark brown, the outer feather tipped with white; wings very short; quills ash-grey on the inner web, dark brown on the outer; feet yellowish; bill yellowish white, with a black tip. Length five inches and a half. Eggs greenish white, speckled all over, and especially at the larger end, with brown and ash-grey.

This species received its name from having been first shot on Bexley Heath, near Dartford in 1773. It has since been observed on furzy commons in several of the southern and western counties, but is local and nowhere abundant. In its habits it resembles the Stone and Furze Chats, perching on the upper sprays of the furze and whitehorn, but never still for a minute, throwing itself into various attitudes, erecting its crest and tail at intervals, frequently rising into the air with most fantastic movements, catching insects on the wing, and either returning to the same twig, or making a short flight to some other convenient bush. The syllables 'cha cha cha' are several times repeated when the bird is irritated. Its note is commonly Pitchou, hence its French name. It keeps quite aloof from human habitations, and is so timid that on the approach of an observer, it creeps into a bush, and remains concealed until the danger is past. The nest of goose grass and soft bits of furze, wool and moss is placed in the fork of a furze-bush selected for its thickness and difficulty of access. It is somewhat wandering, but may be called a resident in the South, gradually extending northwards. Many specimens have been observed in mid-winter, and Rennie states that he has seen one as early as the end of February hovering over furze and singing like a Whitethroat.

THE REED WARBLER ACROCÉPHALUS STRÉPERUS

Upper parts of a uniform reddish brown, without spots; wing-feathers brown, edged with olive; a white streak between (not over) the eye and bill; throat white; under plumage yellowish white, the sides tinged with reddish; tail long, rounded. Length five and a half inches; breadth seven and a half. Eggs dull greenish white, speckled with olive and light brown, especially towards the larger end.

Both the Sedge and the Reed warblers are jaseuses, or chatterers, with rounded tails; but the Sedge Warbler has its upper plumage spotted with dark brown, and a white line above its eye, while the upper plumage of the Reed Warbler is of a uniform pale brown, and the light mark is absent from above the eye. The haunts and habits of the two birds are precisely similar, but the Reed Warbler is by far the less common of the two; for while the Sedge Warbler is sure to be found wherever the Reed Warbler has been observed, the converse by no means follows. The parts of England in which it appears to be most frequent, are East Riding of Yorkshire, Essex, Surrey, Kent, Suffolk, and Norfolk. In the reed-beds on the banks of the Thames, between Erith and Greenwich, it is common.

"The nest of the Reed Warbler is often elegantly built, and generally fixed to three or four reed-stems. It is composed of slender blades of grass, interwoven with reed-tops, dry duckweed, and the spongy substance which covers many of the marsh ditches; and, here and there, a long piece of sedge is wound securely around it; the lining is of the finer flowering stems of grass, intermixed with a little horsehair. It is a deep and solid structure, so that the eggs cannot easily roll out; it is firmly fastened to the reeds in tidal ditches and rivers, at the height of three or four feet from the water, but in still ditches often not more than a foot. In windy weather, when wading through the reed-beds, I have seen nests, with both old and young in them, blown nearly to the surface of the water; but the birds fix their claws firmly to the sides of the nest, with their heads to windward, and thus ride as securely in their cradle as a sailor does in his cot or hammock." The Cuckoo occasionally chooses the Reed Warbler's nest to lay its eggs in, for the same writer remarks--"At the latter end of July, 1829, while reading in my garden, which adjoins a market garden, I was agreeably surprised to see a young Cuckoo, nearly full-grown, alight on the railings between the two, not more than a dozen yards from where I was sitting. Anxious to see what bird had reared this Cuckoo, I silently watched his movements, and had not waited more than a minute, when a Reed Warbler flew to the Cuckoo, who, crouching down with his breast close to the rail, and fluttering his wings, opened wide his orange-coloured mouth to receive the insect his foster-mother had brought him. This done, the Reed Warbler flew away for a fresh supply of food. The difference in the size of the two birds was great; it was like a pigmy feeding a giant. While the Reed Warbler was absent, the Cuckoo shuffled along the rail, and hopped upon a slender post to which it was nailed, and which projected about eight inches above the rail. The Reed Warbler soon returned with more food, and alighted close to the Cuckoo, but on the rail beneath him; she then began to stretch herself to the utmost to give him the food, but was unable to reach the Cuckoo's mouth, who, like a simpleton, threw his head back, with his mouth wide open, as before. The Reed Warbler, by no means at a loss, perched upon the Cuckoo's broad back, who, still holding back his head, received in this singular way the morsel brought for him." The song of the Reed Warbler is loudest and at its best during the evening twilight.

MARSH WARBLER ACROCÉPHALUS PALUSTRIS

Upper parts olive-green without any reddish tinge; legs and feet pale brown.

The Marsh Warbler is local in its occurrence, in the south of England. It nests in drier places than the Reed Warbler and its song is different, being much more melodious, and uttered more boldly. Close to low bushes, or among meadow-sweet, nettles and cow-parsnip, you may find its nest, which is made of fine rounded stalks of grass and lined with horsehair. There are five to seven eggs, whiter in ground colour than those of the Reed Warbler. The Marsh Warbler comes each spring to the neighbourhood of Taunton, but it is still a somewhat rare species.

THE SEDGE WARBLER ACROCÉPHALUS PHRAGMÍTIS

Upper plumage olive-grey, the centre of each feather tinged with brown; above the eyes a broad yellowish white stripe; under, yellowish white, more or less tinged with red; throat white; tail rounded, of moderate length, of a uniform ash-brown. Length four and a half inches; breadth seven and a half. Eggs dirty white, mottled all over with dull yellowish brown.

On the banks of reedy and bushy rivers, in marshes, withy holts, wherever, in fact, there is fresh water associated with enough vegetation to shelter and conceal, this bustling little bird is a constant summer visitor; restless in its habits, and courting notice by its twittering song, from the time of its arrival to that of its departure. It is usually first detected by its rapidly repeated note, which it utters while performing its short flights from bush to bush, and while creeping in and out among reeds and rushes. The fisherman knows it well, and is often tempted to withdraw his eye from his fly or float, to watch its movements on the opposite bank. From its unceasing babble, ploughboys call it a 'chat', a name which exactly answers to the French name of the group to which it belongs--'Jaseuses'. Its note is remarkable neither for volume nor sweetness, and, like that of unfeathered chatterers, seems to carry more noise than meaning. To a certain extent the bird is a mimic, as it imitates such notes of other birds as are within the compass of its little throat. I was walking one morning in May by the banks of a canal not far from a village, when I remarked the exact resemblance between a portion of its song and the chirrup of a House Sparrow. Intermixed with this, I detected the note of some other bird; but, familiar though it sounded, I ransacked my memory in vain to discover from whom it was purloined. Pursuing my walk towards the houses, I heard the note of some Guinea-fowls; not the 'come-back' cry, but the 'click-click' which every one knows so well. Of this the Sedge Warbler had caught exactly both the key and the time; the two notes were in fact identical, except that they were performed on instruments of different calibre. Like other chatterers, who, when they have finished their song, are easily provoked to begin again, the Sedge Warbler, if he does occasionally retire to a bed of reeds and there holds his peace, may be excited to repeat his whole story over again, with variations and additions, by flinging a stone into his breathing-place. And not content with babbling all day, he extends his loquacity far into the night; hence he has been called the Sedge Nightingale, but with doubtful propriety, for, with all the will perhaps to vie with that prince of songsters, the zinzinare of the Nightingale is far beyond his powers. Yet in spite of his obtrusiveness, he is an amusing and a pleasant companion to the wanderer by the river's side: his rivalry is devoid of malice, and his mimicry gives no one pain. While at rest--if he is ever to be detected in this state--he may be distinguished from all other birds frequenting similar haunts by his rounded tail, and a light narrow mark over each eye. His food consists of worms, insects, and fresh-water mollusks, for which he hunts among the stems of aquatic plants. As an architect, he displays great skill, constructing his nest among low bushes, never at any great distance from the water, about a foot from the ground. It is composed of stems and leaves of dead grass, moss and fine roots, and lined with hair, wool, feathers, and the down of various marsh plants. The structure is large, compact, and deep, suspended from, rather than built on, its supports. The eggs are usually five or six in number, though as many as seven have been sometimes found.

THE GRASSHOPPER WARBLER LOCUSTELLA NÆVIA

Upper parts light brown, with a tinge of green, and presenting a spotted appearance, owing to the centres of the feathers being darkest; tail long, rounded at the extremity and tapering towards the base; under parts whitish brown, the breast marked with darker spots; feet and toes light brown. Length five and a half inches; breadth seven and a half. Eggs reddish white, closely speckled with darker red.

As long ago as the time when a stroll of five-and-twenty miles fatigued me less than a journey of ten does now--when I returned from my botanical rambles with tin boxes, hands and pockets, laden with stores of flowers, ferns, and mosses, my homeward path often led me through a certain valley and wood on the skirts of Dartmoor, known by the names of Bickleigh Vale and Fancy Wood. It often happened that twilight was fading into gloom when I reached this stage in my wanderings--the last of the evening songsters had hushed its note; for this county, beautiful as it is, offers not sufficient attraction to the Nightingale; yet I never passed this way under such circumstances without feeling myself compelled to stop once and again to listen to the monotonous whir of what I had been told, and what I believed to be the note of the large green grasshopper, or locust. Monotonous is, perhaps, not the right word to use, for an acute ear can detect in the long unmusical jar a cadence descending sometimes a semitone, and occasionally almost a whole note; and it seemed besides to increase in loudness for a few seconds and then to subside a little below the ordinary pitch; this fall is chiefly at the breeding season. Whether the difference was produced by a rising and lulling of the breeze, or whether the musician actually altered its note and intensity of noise (or must I call it music?), I could never decide. As long as I fancied the performer to be an insect, I was inclined to believe that one of the first suppositions was correct; for it seemed hardly possible that the purely mechanical action of an insect's thighs against its body could produce variety of sound--as well expect varied intonations from a mill-wheel or saw-pit. Attentive observation, and the knowledge that the noise in question proceeded not from the exterior of an insect, but from the throat of a bird, has led me to form another conclusion. I am not surprised at my having fallen into the error; for the song of this bird is but an exaggeration of the grasshopper's note, and resembles the noise produced by pulling out the line from the winch of a fishing-rod, no less continuous is it, nor more melodious. Many years afterwards, when the memory of these pleasant wanderings had faded away, I happened one evening in May to be passing across a common in Hertfordshire, skirted by a hedge of brushwood, when the old familiar sound fell on my ear like a forgotten nursery melody. The trees not being in their full foliage, I was not without hope that I might be able to get a sight of the performer, whom I now knew to be a bird, and I crept quietly towards the spot whence the noise proceeded. Had it been singing in a copse-wood instead of a hedge, I should certainly have failed, for there is the same peculiarity about its note that there is about that of the insect--you cannot make up your mind exactly whereabouts the instrument which makes the noise is at work. The note, when near, is continuous, monotonous, and of equal loudness throughout; it might be a minute spinning-wheel revolving rapidly, or a straw pipe with a pea in it blown with a single breath and then suddenly stopping. But whether the performance is going on exactly before you, a little to the right, or a little to the left, it is hard to decide. I approached to within a few yards of the hedge, and peered through the hazel rods, now decorated with drooping tufts of plaited leaves, but all in vain. I went a step or two nearer; the sound ceased, and the movement of a twig directed my attention towards a particular bush, on which I saw a little bird, about as big as a Hedge Sparrow, quietly and cautiously dropping branch by branch to the ground. In a few minutes I observed it again a few yards off, creeping with a movement resembling that of the Nuthatch up another bush. Having reached to nearly the summit it became motionless, stretched out its neck, and keeping its mandibles continuously open and slightly elevated, commenced its trill again; then it shuffled about for some seconds and repeated the strain. It now seemed to descry me, and dropping to the ground as before, reappeared a few yards off. I fancied that while actually singing its feathers were ruffled; but in the imperfect twilight I could not decide positively. That it kept its mandibles motionless while singing, I had no doubt. Half an hour afterwards, at a quarter to eight, I returned from my walk, and observed it several times go through precisely the same manoeuvres. On no occasion did it make a long flight, but even when I scared it by throwing a stone into the hedge near it, it merely dropped to the ground, and in a minute or two was piping from another bush. I have not found, as some authors say, that it resorts only to the vicinity of watery places. The one which I saw on this occasion had located itself for the summer several miles from a stream; and others which I have heard night after night had settled down on the skirts of a dry common, watered only by the clouds. Its nest I have sought for in vain.
