THE CHIFF-CHAFF PHYLLÓSCOPUS RUFUS

Upper parts olive-green tinged with yellow; above the eyes a narrow, faint, yellowish, white streak; under parts yellowish white; feathers of the leg dirty white; second primary equal to the seventh; third, fourth, fifth, and sixth with the outer web sloped off at the extremity; under wing-coverts primrose-yellow; feet slender; legs nearly black. Length four inches and a half; breadth seven and a quarter. Eggs white, sparingly spotted with dark purple.

Whatever question there may be whether the name of Willow-warbler be appropriately applied to the last species, there can be no doubt that the Chiff-chaff is well named. Let any one be asked in the month of May to walk into a wood and to hold up his hand when he heard a bird call itself by its own name, 'Chiff-chaff', he could not possibly fall into an error. The bird is so common that it would be difficult to walk a mile in a woodland district without passing near one or more, and having little to say, it seems never weary of repeating its tale, 'Chiff, chaff, cheff, chiff, chaff': the syllables have a harsh sound pronounced by human lips, but when chanted in the silvery notes of a little bird, in the season of primroses and wild hyacinths, and accompanied by the warble of the Hay-bird, the full song of the Thrush, and the whistle of the Blackbird, they contribute not a little to the harmony of the woods.

For two successive years a little yellowish bird, scarcely bigger than a wren, has established himself in my garden about the middle of April, and sedulously devoted himself to clearing away the aphides which infested some China roses trained against the walls of my house. Occasionally he would flutter against the windows, and give his attention to the spiders and gnats which nestled in the corners of the panes. The first year I took him for a Hay-bird, but, only too grateful for his kind offices, I was careful not to molest him. When, however, he appeared a second year, exactly at the same season, and performed a series of manoeuvres so precisely similar that it was impossible to doubt that the bird was not merely of the same species, but the same individual, I watched him more closely. The dark colour of his feet, as observed from within the house, as he was fluttering against the glass, decided the point that he was not a Hay-bird, and when he retired to an apple-tree hard by and treated himself to a song after his repast, no doubt remained that he was a Chiff-chaff. It is not often that the Chiff-chaff is thus familiar in its habits. More frequently it makes its abode in woods and groves, resembling the Hay-bird so closely in size, colour and habits, that to distinguish the two is very difficult. The difference of note, however, is decisive; and the colour of the feet (when the bird is near enough to admit of being thus distinguished) is another certain criterion. The two birds frequent the same trees without rivalry or jealousy. The Chiff-chaff is the earliest of our spring visitors, arriving the middle of March, and it sings all through the summer; I have heard it as late as the thirtieth of September. The nests, popularly called 'wood-ovens', are alike and placed in similar situations; their eggs are of the same size and shape, but those of the Chiff-chaff are spotted with very dark purple instead of rust colour. A few occasionally remain with us all the year, feeding on winter gnats and the pupæ of small insects, but remaining wholly silent. Other names by which it is known are 'Chip-chop' and Lesser Pettichaps.

THE WILLOW-WARBLER PHYLLÓSCOPUS TRÓCHILUS

Upper parts bright olive-green; a narrow streak of yellow over the eye; under parts yellowish white, palest in the middle; feathers of the leg yellow; second primary equal to the sixth; third, fourth, and fifth with the outer web sloped off at the extremity; feet stoutish; legs light brown. Length nearly five inches; breadth eight. Eggs white, more or less speckled with rust colour.

There seems to be no sufficient reason why this bird should be named Willow-warbler or Willow-wren, as it shows no special preference for willows, nor does it frequent watery places. The popular name, 'Hay-bird', is, I think, the better of the two; for, except in the extreme west of England, wherever there are hayfields and trees these birds are to be found; they build their nests principally of hay, and very frequently place it in the border of a hay-field. But, by whatever name it is known, it is a cheerful and active little bird, to which our woods and groves are much indebted for their melody. It is abundant and generally diffused, arriving in England early in April, and remaining until the middle of September. During the greater part of this period, it may be seen fluttering about the tops of trees, hunting the twigs and leaves for insects, and occasionally catching flies on the wing. It often, too, descends to the ground, and picks up insects among the herbage. I have never heard it sing on the ground; but while employing itself aloft, it rarely allows more than a few minutes to elapse without going through its short and sweet song. This, though very agreeable, possesses no great variety, and is composed of about twenty or thirty notes, the latter ones of which are repeated rapidly, and form a natural cadence. For many years this pleasant little melody, or the simpler song of the Chiff-chaff, has been the first sound I have heard to announce the arrival of the summer birds of passage; perhaps it is on this account that it is with me, at all seasons, a favourite rural sound.

Ornithologists seem well agreed that the Willow-warbler's food consists entirely of insects. This may be so, but I am much mistaken if a brood of this species annually hatched in a bank of furze adjoining my garden, do not, in conjunction with Blackcaps and Whitethroats, pay daily visits to a certain row of red raspberries in my garden. It may be that they come only in quest of aphides, but I have certainly seen them in dangerous proximity to clusters of the ripest fruit, which, when they were scared away, bore evident marks of having been pecked by birds. The nest of the Hay-bird resembles that of the Wood-warbler, but it is lined with feathers. The eggs are usually from five to seven, and of the same size and shape, but the spots are rust-coloured and limited in number.

THE WOOD-WREN PHYLLÓSCOPUS SIBILÁTRIX

Upper plumage bright yellowish green; a broad streak of sulphur-yellow over the eye; sides of the head, throat, insertion of the wings and legs bright yellow; rest of the under plumage pure white; second primary equal to the fourth, third and fourth with the outer web sloped off at the extremity; legs pale brown. Length five inches and a half; breadth eight and three quarters. Eggs white, speckled so thickly with purplish brown as almost to conceal the ground.

The Wood-warbler, Willow-warbler, and Chiff-chaff resemble each other so closely in size, colour, and habits, that except by a practised observer, they are likely to be mistaken for one another. In song, however, they differ materially, and as this is begun early, and continued till very late in the season, it affords ready means of discriminating the species. The Wood-warbler, or Wood-wren as it is now called, arrives in England towards the end of April, and betakes itself to woodland districts, where it spends the greater portion of its time among the upper branches of lofty trees, constantly moving from place to place with rapid irregular flight, and frequently repeating its short and peculiar song. It feeds exclusively on insects, which it occasionally catches on the wing. Its song is difficult to describe. The name by which it is popularly known in some parts of France, Touïte, is derived from the syllable 'tweet', which, rapidly and continuously repeated many times, constitutes its song. These notes are uttered in a sweet tone, and with a tremulous accent, and are unlike those of any other bird. Gilbert White, who appears to have been the first who noticed the bird, describes it as "joyous, easy, and laughing". The last notes of its strain are accompanied by a quivering of the wings and tail, which accounts for their tremulous sound.

The Wood-warbler is much less frequent than either the Willow-warbler or Chiff-chaff, and on a close inspection may be distinguished by its superior size, by the pure white of its under tail-coverts, and by the bright yellow line above the eye. The nest is composed of grass, ferns, and moss, and lined with fine grass and hair; it is covered with a dome, an entrance being left sufficiently large to allow its contents to be seen, and is placed on the ground, in or near a wood, among thick herbage, or against the stump of a tree. The eggs are from five to seven in number, almost round, and so thickly spotted with purple-brown that the ground is almost invisible.

SUB-FAMILY REGULINÆ

THE GOLD-CREST RÉGULUS CRISTÁTUS

Upper parts olive, tinged with yellow; cheeks ash colour, without streaks; wing greyish brown, with two transverse white bands; crest bright yellow, tipped with orange and bounded on each side by a black line; under parts yellowish grey. In the female the crest is lemon colour, and the other tints are less brilliant. Each nostril is covered by one buff feather. Length three inches and a half. Eggs cream colour, minutely mottled at one end.

The Gold-crest, Golden-crested Regulus, or Golden-crested Wren, though not exceeding in dimensions some of the larger humming-birds, and though decorated with a crest equalling in brilliancy of colour the gay plumage of tropical birds, is a hardy little fellow, able to bear without shrinking the cold of an English winter, and to keep his position among the branches of high trees in the stormiest weather. Even during a heavy gale I have watched Gold-crests fluttering from branch to branch, and busily hunting for food, though the trees were waving like reeds. They are most numerous in winter, as a considerable number migrate southwards in October, but a great many remain with us all the year, preferring those districts where there are fir-plantations. Their whole life is spent in the air; I at least have never observed one on the ground. Their food consists of the insects which infest the leaves and twigs of trees; and I have seen them capture small moths on the wing. While hunting for food, which appears to be all day long, they are never still, fluttering from branch to branch, hanging in all attitudes, and peering in all directions. From time to time they utter their thin and wiry call-note, which is by some compared to the cry of the Shrew. It might be mistaken for the jarring noise made by two branches which cross one another, or that of a damp finger rubbed lightly along a pane of glass. Early in spring the song commences; it is composed of about fifteen short notes, rapidly uttered at an exceedingly high pitch, and ending with a yet more rapid cadence. By the call-note or song the vicinity of the bird is far more frequently detected than by its actual appearance; for the branches of firs in woods are mostly at a considerable height from the ground, and our 'little king' (saving his majesty) is hard to be distinguished from a fir-cone, except when he is in motion. Gold-crests are eminently social birds; they generally hunt in parties of half a dozen or more, and do not often change their hunting-ground; at least I infer as much from the fact that on various occasions I have observed the same bird on the same clump of trees, at intervals extending over several weeks. I could scarcely have been mistaken in the identity of the bird, as it had lost a leg, by what accident I know not; but the loss did not at all interfere with its activity or spirits. Their sociability extends sometimes to birds of other kinds, as the Creeper and the Tits of several species have been seen hunting in company with them. The habits of these birds being similar, they perhaps associate from a feeling of mutual protection, just as Sparrows, Buntings, and Finches make common cause, when they invade our rick-yards. The Gold-crests are, however, naturally less wary than any of the Tits. These last will at once decamp if disturbed, but Gold-crests will continue their hunting without taking any notice of a spectator. In autumn large flocks sometimes arrive on our east coast extending across England and on into Ireland. In April a return migration takes place. The nest of the Gold-crest is a beautiful structure. Its external form is nearly that of a globe, with a contracted opening at the top. It is composed of moss and lichens, interwoven with wool and lined thickly with feathers. It is usually placed among the boughs of a silver-fir or spruce-fir, in such a manner as to be partially suspended from one branch and supported by another. The bird seems neither to court nor to shun the vicinity of human beings; as I have found nests in the most lonely woods, and I have seen one in the branches of a spruce-fir, so close to my house that I could look into the nest from my bedroom windows, and watch the old birds feeding their young. The eggs vary in number from five to eight, they are almost globular, and smaller than those of any other British bird. This is scarcely surprising, seeing that the weight of a recently killed adult male which I have before me is eighty-seven grains; so that five and a half full-grown birds weigh but an ounce.
