The Whitethroat is in England the most common of all the migratory warblers, and is generally diffused. It is essentially a hedge-bird, neither taking long flights nor resorting to lofty trees. Early in May it may be detected in a hawthorn or other thick bush, hopping from twig to twig with untiring restlessness, frequently descending to the ground, but never making any stay, and all the while incessantly babbling with a somewhat harsh but not unpleasant song, composed of numerous rapid and short notes, which have but little either of variety or compass. Occasionally it takes a short flight along the hedge, generally on the side farthest from the spectator, and proceeds to another bush a few yards on, where it either repeats the same movements, or perches on a high twig for a few seconds. From time to time it rises into the air, performing curious antics and singing all the while. Its short flight completed, it descends to the same or an adjoining twig; and so it seems to spend its days. From its habit of creeping through the lower parts of hedges, it has received the popular name of 'Nettle-creeper'. From the grey tone of its plumage, it is in some districts of France called 'Grisette', and in others, from its continuous song, 'Babillarde', names, however, which are popularly applied without distinction to this species and the next. While singing it keeps the feathers of its head erected, resembling in this respect the Blackcap and several of the other warblers. Though not naturally a nocturnal musician, it does not, like most other birds, when disturbed at night, quietly steal away to another place of shelter, but bursts into repeated snatches of song, into which there seems to be infused a spice of anger against the intruder.[4] Its food consists of insects of various kinds; but when the smaller fruits begin to ripen, it repairs with its young brood to our gardens, and makes no small havoc among raspberries, currants, and cherries. It constructs its nest among brambles and nettles, raised from two to three feet from the ground, of bents and the dry stems of herbs, mixed with cobweb, cotton from the willow, bits of wool, and horsehair. It usually lays five eggs.

[4] 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.
