Part 28

The blackcap lives on insects, which it often captures on the wing, and on fruits, and is fond of raspberries and currants. Its autumn migration is in September.

Garden Warbler.

Sylvia hortensis.

Upper plumage greyish brown tinged with olive; below the ear a patch of ash-grey; throat dull white; breast and flanks grey tinged with rust colour; rest of under parts dull white. Length, five and a quarter inches.

This warbler was first described as a British species by Willughby, more than two centuries ago, under the name of ‘prettichaps’; and Professor Newton, in a note to Yarrell’s account of it, says: ‘This name (prettichaps) seems never to have been in general use in England, or it would be readily adopted here.’ The old name of prettichaps, it may be mentioned, does not appear to be quite obsolete yet: I have heard it in Berkshire, where it was applied indiscriminately to the garden warbler and blackcap.

The garden warbler is not common anywhere. In Ireland it is scarcely known; in Scotland, Wales, and a large part of England it is very rare. It is most frequently to be met with in the southern counties, especially in Hampshire. Very curiously, Gilbert White did not know this warbler, which may now be heard singing any day in spring in the neighbourhood of Selborne village.

The garden warbler is often said to rank next to the blackcap as a melodist. The songs of these two species have a great resemblance; it is, indeed, rare to find two songsters, however closely allied, so much alike in their language. The garden warbler’s song is like an imitation of the blackcap’s, but is not so powerful and brilliant: some of its notes possess the same bright, pure, musical quality, but they are hurriedly delivered, shorter, more broken up, as it were. On the other hand, to compensate for its inferior character, there is more of it; the bird, sitting concealed among the clustering leaves, will sing by the hour, his rapid, warbled strain sometimes lasting for several minutes without a break.

The garden warbler is a late bird, seldom arriving in this country before the end of April. It builds a rather slight nest, in a bush near the ground, of dry grass and moss, lined with hair and fibrous roots. The eggs are five in number, and are dull white, sometimes greenish white, blotched and speckled with dull brown and grey.

The food of this warbler consists of small insects; and it is also fond of fruit and berries.

Six species of the genus Sylvia are included in books on British birds: the four already described, the orphean warbler (Sylvia orphea), an accidental visitor from Central and Southern Europe, and the barred warbler (Sylvia nisoria), from Central, South, and East Europe.

Furze-Wren, or Dartford Warbler.

Melizophilus undatus.

Upper parts greyish black; wing-coverts and feathers blackish brown; outer tail feathers broadly, and the rest narrowly, tipped with light brownish grey; under parts chestnut-brown; belly white. Tail long; wings very short. Length, five inches.

The furze-wren, never a common species in this country, is now become so scarce, and is, moreover, so elusive, that it is hard to find, and harder still to observe narrowly. Its somewhat singular appearance among the warblers--its small size, short, rounded wings, great length of tail, and very dark colour--its peculiar song, and excessively lively and restless habits, and the fact that it was first discovered in this country (1773), where, though so small and delicate a creature, it exists on open, exposed commons throughout the year, have all contributed to make it a fascinating subject to British ornithologists. In England it inhabits Surrey and the counties bordering on the Channel; but it has also been found in suitable localities in various other parts of the country, and ranges as far north as the borders of Yorkshire. I have sought for it in many places, but found it only in Dorset. Forty or fifty years ago it was most abundant in the southern parts of Surrey; it was there observed by the late Edward Newman, who gave the following lively and amusing account of its appearance and habits in his ‘Letters of Rusticus on the Natural History of Godalming’ (1849): ‘We have a bird common here which, I fancy, is almost unknown in other districts, for I have scarcely ever seen it in collections.... I mean the furze-wren, or, as authors are pleased to call it, the Dartford warbler. We hear that the epithet of Dartford is derived from the little Kentish town of that name, and that it was given to the furze-wren because he was first noticed in that neighbourhood. ... If you have ever watched a common wren (a kitty-wren we call her), you must have observed that she cocked her tail bolt upright, strained her little beak at right angles, and her throat in the same fashion, to make the most of her fizgig of a song, and kept on jumping and jerking and frisking about, for all the world as though she was worked by steam; well, that’s more the character of the Dartford warbler, or, as we call her, the furze-wren. When the leaves are off the trees and the chill winter winds have driven the birds to the olive-gardens of Spain, or across the Straits, the furze-wren is in the height of his enjoyment. I have seen them by dozens skipping about the furze, lighting for a moment on the very point of the sprigs, and instantly diving out of sight again, singing out their angry, impatient ditty, for ever the same. Perched on the back of a good tall nag, and riding quietly along the outside, while the foxhounds have been drawing the furze-fields, I have often seen these birds come to the top of the furze.... They prefer those places where the furze is very thick, and difficult to get in.... And although it is so numerous in winter, and so active and noisy when disturbed by dogs and guns, still, in the breeding season it is a shy, skulking bird, hiding itself in thick places, much in the manner of the grasshopper lark, and seldom allowing one to hear the sound of its voice.’

Spring is, however, the season of the furze-wren’s greatest activity: its lively gestures, antics, and dancing motions on the topmost sprays of the bushes are then almost incessant, as it pursues the small moths and other winged insects on which it feeds; and its curious and impetuous little song is then delivered with the greatest vigour. It has also a harsh, scolding note, uttered several times in rapid succession, and a loud musical call-note.

The nest is placed among the dense masses of the lower, dead portion of a thick furze-bush. It is a flimsy structure, composed of dead furze-leaves, small twigs, and grass-stems, lined with finer stems, and sometimes with horsehair. Four or five eggs are laid, white in ground-colour, sometimes tinged with buff or with greenish, thickly spotted and freckled with pale brown over paler brown and grey markings. Two broods are reared in the season.

Golden-crested Wren, or Goldcrest.

Regulus cristatus.

Upper parts olive tinged with yellow; cheeks ash-colour; wing greyish brown, with two transverse white bands; crest bright yellow in front, orange behind, bounded by two black lines; under parts yellowish grey. Female: colours not so bright; crest lemon-colour. Length, three and a half inches.

The golden-crested wren has the distinction of being the smallest British bird; it is also one of the most widely distributed, being found throughout the United Kingdom. Furthermore, it is a resident throughout the year, is nowhere scarce, and in many places is very abundant. Yet it is well known only to those who are close observers of bird life. The goldcrest is not a familiar figure, owing to its smallness and restlessness, which exceed that of all the other members of this restless family of birds, and make it difficult for the observer to see it well. Again, it is nearly always concealed from sight by the foliage, and in winter it keeps mostly among the evergreens, and at all times haunts by preference pine, fir, and yew trees. In the pale light of a winter day, more especially in cloudy weather, it is hard to see the greenish, restless little creature in his deep green bush or tree. Standing under, or close to, a wide-spreading old yew, half a dozen goldcrests flitting incessantly about among the foliage in the gloomy interior of the tree look less like what they are than the small flitting shadows of birds.

In March, and even as early as the latter part of February, the male is frequently heard uttering his song; but he is not of the songsters that perch to sing, and pour out their music deliberately and with all their might. The goldcrest’s song comes in as a sort of trivial distraction or relief--a slight interlude between the more important acts of passing from one twig or spray to another, and snatching up some infinitesimal insect so quickly and deftly that to see the action one must watch the bird very closely indeed. And the music, of which the musician makes so little, is of very little account to the listener. It is the smallest of small songs--two notes, almost identical in tone, repeated rapidly, without variation, two or three times, ending with a slight quaver, scarcely audible, on the last note. The sound is sharp and fine, as of young mice squealing, but not quite so sharp, and more musical; it is a sound that does not travel: to hear it well one must stand not farther than a dozen or fifteen yards from the singer.

Yarrell has the following passage on the song of the goldcrest: ‘Pennant says he has observed this bird suspended in the air for a considerable time over a bush in flower, while it sang very melodiously; but this peculiarity does not appear to have been noticed by other naturalists.’ I have observed the male, in the love season, hovering just above the bush, in the topmost foliage of which its mate was perched, and partially hidden from view. It is when engaged in this pretty, aërial performance, or love-dance, that the golden-crested wren is at his best. The restless, minute, sober-coloured creature, so difficult to see properly at other times, then becomes a conspicuous and exceedingly beautiful object; it hovers on rapidly-vibrating wings, the body in almost a vertical position, but the head bent sharply down, the eyes being fixed on the bird beneath, while the wide-open crest shines in the sun like a crown or shield of fiery yellow. When thus hovering it does not sing, but emits a series of sharp, excited, chirping sounds.

The goldcrest builds a pendent nest, made fast to the small twigs under a branch of yew or fir, and uses a variety of materials--fine dry grass, leaves, moss, and webs--closely woven together, lining the cavity with feathers. It is a very ingenious and pretty structure. The eggs laid are from six to ten, of a pale yellowish white, spotted and blotched, chiefly at the large end, with reddish brown.

In the autumn, in the months of October and November, a great migratory movement takes place among the goldcrests in the north of Europe; and in some seasons incredible numbers of these small travellers arrive, often in an exhausted condition, in Northumberland and on the east coast of Scotland. After resting close to the sea for a day or two, they resume their journey, and distribute themselves over the country.
