Part 5
This species is scarcer and more local than the Willow Wren. In Scotland it is local and is only a straggler to the north of that country and the surrounding islands.
THE SIBERIAN CHIFFCHAFF Phylloscopus tristis, Blyth
One example of this small warbler, that breeds in Western Siberia, migrating to Turkestan and India in winter, was obtained at a lighthouse off the Orkneys in 1902. It is rather smaller and browner than our common Chiffchaff and has the under parts buffish white. It may, however, always be recognised by the shortness of the second primary, which comes between the seventh and the eighth, or is even shorter than the eighth.
THE WILLOW WREN Phylloscopus trochilus (Linnæus)
The Willow Wren is closely allied to the Chiffchaff and so like it in general appearance as to need a critical examination, when dead, to enable it to be recognised. In habits also there is little difference to be noted. Its range is more extensive, for as far north as the birch woods extend, this hardy little wanderer makes his home, retiring at the end of summer to Southern Europe and Africa. Throughout our islands it is extremely common. Arriving about the last week of March, it at once makes its presence known by its bright little song, which is very short and somewhat resembles the Chaffinch's; it is repeated again and again, and may be heard right through the summer and sometimes again after the moult in the late autumn, just before their final departure.
The nest is similar in size, shape, and materials to that of the Chiffchaff, but differs in its position, being generally placed very near and often right on the ground, always well concealed in the undergrowth, whereas with the Chiffchaff it is always off the ground, sometimes only an inch or two, but more often some eighteen inches or two feet. The eggs are white with pale rufous spots; these markings are much paler than on those of the Chiffchaff, less clean cut, and more numerous.
Apart, however, from the breeding birds, an enormous number of Willow Wrens pass through this country at migration time. England seems to lie in the main track of these birds when they are making for their summer quarters in higher latitudes. From early April to the middle or end of May they simply pour through this country in incredible numbers. The whole extent of the south coast is involved, and often for several days at a time they arrive in millions. These birds pass straight on, relentlessly pursuing their course, and having crossed the Channel one night, prepare during the following day for a still longer journey across the North Sea during the coming night. Early in August the return journey commences, and in still greater numbers they steadily pass southwards, till by October they are, let us hope, enjoying peace and plenty under sunny skies.
Extremely like the Chiffchaff, but rather larger, brighter in colour, and with paler legs. Its distinctive characteristics have been noted under the preceding species. Length 4·9 in.; wing 2·7 in.
THE WOOD WREN Phylloscopus sibilatrix (Bechstein)
Although a member of the same family as the last two species, this bird is much more local. It is not until the end of April that he reaches our shores and his clear and melodious little song, which may be syllabled as "chit, chit, chit, chit, tri-tr-tr-tre," can be heard. His favourite haunts are suitable woods where large timber, especially beech, abound. Here he may be seen as, with the restless activity so characteristic of his family, he searches among the upper branches of the trees for those insects which, with berries of all kinds, form his staple food.
At the foot of some beech-tree, on the ground, or more rarely in some tangled thicket, the nest is built and well concealed by the use of materials similar to the surroundings among which it is placed. It is lined with grass and horsehair, but feathers, so freely used by the Chiffchaff and Willow Wren, are never found. The eggs are white, very thickly and uniformly mottled with dark red. After the young are hatched it becomes silent, and leaves us early in September.
The adult has the upper parts of a bright yellowish green, with a characteristic yellow streak above and behind the eye. The wings are brown edged with yellowish green. Throat and breast sulphur yellow, rest of under parts white. Bill and legs brown. Length 5·2 in.; wing 3·1 in. The larger size and brighter coloration are distinctive of this species.
It is a local bird, but may be found in suitable spots throughout the United Kingdom. In the north, however, it becomes rarer.
THE RUFOUS WARBLER Aedon galactodes (Temminck)
This handsome species is only a summer migrant to the South of Spain, and the few that have occurred in England are merely stragglers carried out of their course. It has been taken in Sussex and once in Devon, in all cases during the autumn.
It is a conspicuous bird, like a large pale-coloured Nightingale, and may be recognised by its fan-shaped tail with black subterminal spots and white tips. Length 6·5 in.; wing 3·5 in.
RADDE'S BUSH WARBLER Lusciniola schwarzi (Radde)
This species, which breeds in North-Eastern Siberia and migrates in winter to China and Burma, has only once been obtained in this country, namely in October 1898, by Mr. Haigh, on the Lincolnshire side of the Humber. Mr. Haigh's attention was drawn to it by the loud and powerful note. The general colour above is olive brown, tinged with tawny on the rump. Under parts yellowish white. There is a broad white superciliary stripe, which ends abruptly in a manner characteristic of this species. Length 5·5 in.; wing 2·45 in.
CETTI'S WARBLER Cettia cettii, Marmora
A single example of this species, whose home is in Southern Europe and the Mediterranean basin generally, was obtained in Sussex in May 1904.
The upper parts are chestnut brown, darker on the wings and tail. There is a white superciliary stripe. Under parts white, turning to grey on the breast, flanks, and under tail coverts. Length 5 in.; wing 2·3 in.
THE ICTERINE WARBLER Hypolais icterina (Vieillot)
This fairly common European bird is only a rare visitor to our southern and eastern shores, and has once been taken in Ireland. It breeds in North-Eastern France, Denmark, Scandinavia, and throughout Northern and Central Europe, migrating south-eastwards in autumn, Italy forming apparently the western limit of its route. The eggs are very distinctive, being pale pink with black spots.
The upper parts are greyish olive, the lores and a streak over the eye yellow. Under parts lemon yellow. Length 5·2 in.; wing 3·1 in.
THE MELODIOUS WARBLER Hypolais polyglotta (Vieillot)
Although the presence of this species had long been suspected, as well as the possibility of it having bred with us, it was not until 1897 that the first authenticated example was procured at Burwash in Sussex. It is a southern species, breeding abundantly in Spain, North Africa, and South-Western France. Its eggs very closely resemble those of the Icterine Warbler.
Except for its smaller size, it is very difficult to distinguish this species from the preceding one, but its proportionately shorter wing, its larger bastard primary and the second primary being _shorter_ than the fifth, form unfailing characteristics. Length 4·9 in.; wing 2·5 in.
REED WARBLER Acrocephalus streperus (Vieillot)
A near ally to the Sedge Warbler, this bird seldom reaches this country till the beginning of May, and at once repairs to the reed-beds, where his whole life, except when actually migrating, is spent. Wherever suitable reed-beds occur in the southern and eastern parts of our islands, he is fairly abundant and reveals his presence by his song, which is a harsh medley of notes volubly rattled out, and somewhat like that of the Sedge Warbler. It is easy to hear him, but to see him is a task requiring much patience and careful watching. He keeps entirely concealed by the reeds among which he lives, creeping along from one to another and assuming all kinds of strange attitudes. Now he hangs head downwards, or again, grasping a neighbouring reed with one foot, he will swing himself round and climb straddle-legged up two reeds, till on reaching the top he will perhaps take a short flight, only to dive in again a few feet farther on.
The nest is a most beautiful structure, carefully supported on four or five growing reeds which pass right through its walls and thus hold it secure. For the size of the bird it is extremely deep, a wise provision to prevent the eggs from being rolled out when the reeds are bent with the wind. The materials used are dry grass, bents, and moss, with a lining of finer materials. The eggs, four in number, are pale green, thickly freckled and mottled with a darker tone of the same colour.
When the young are hatched the inside of their mouths is of a deep red colour with two very conspicuous black spots towards the hinder end of the tongue; at this time the song of the parent ceases and we hear and see but little more of this species. With the autumn gales he leaves us for the marshes of Spain or the deadly swamps of Africa, where the small flies and insects on which he feeds may be found in abundance at all seasons.
The upper parts are of a uniform warm brown, slightly brighter on the rump, and there is a pale buff stripe over the eye. The under parts are white, the flanks and under tail coverts buffish. Length 5·25 in.; wing 2·5 in.
It is unknown in Scotland and Ireland.
THE MARSH WARBLER Acrocephalus palustris (Bechstein)
This species resembles the preceding one so closely that even when examined in the hand, they are hard to distinguish. The general hue is, however, more greenish and less rufous than the Reed Warbler, and the legs are lighter in colour, being brownish flesh instead of yellowish brown. Alike as they are in appearance, their life history is very different. The Marsh Warbler is by no means confined to reeds, but may be found in osier beds, cornfields or coppices, being content, like the Sedge Warbler, with a very small extent of water. It sings its song, which is much sweeter and more melodious than that of the Reed Warbler, from the topmost sprays of its home, and the nests are never suspended in reeds but placed low down in some osier or small bush. The eggs are pale greenish white, blotched and marked with dark green, and are so characteristic that they cannot well be mistaken for those of any other species. It has a wide range in Europe, becoming scarcer towards the west, but in this country it is very local, and restricted as a breeding species to a few places in the south.
Very difficult to distinguish from the Reed Warbler, but the general hue is much greener, and the difference in the colour of the legs has already been noticed. Length 5·25 in.; wing 2·7 in.
THE GREAT REED WARBLER Acrocephalus turdoides (Meyer)
Although common on the neighbouring shores of the Continent, this species has occurred here very seldom. It is abundant throughout Europe in summer as far north as the southern shores of the Baltic, and nests commonly in France, Holland, and Belgium. It inhabits reed-beds or thick cover near the margins of streams, ditches, and ponds. It does not skulk like the Reed Warbler, but, on the contrary, is always sitting on the top of the tallest reeds and flying about from one clump to another.
The upper parts are warm olive brown, with light margins to the wing and tail feathers. There is a dull whitish streak from the bill over each eye. The under parts are buff; chin and belly whitish. Length 7·8 in.; wing 3·75 in.
It has been taken only in the South and East of England.
SEDGE WARBLER Acrocephalus phragmitis (Bechstein)
The presence of a human being seems to spur this delicate species to song, for if, when strolling near some river or pond towards the end of April, we inadvertently pass this little songster, he will at once burst forth with his noisy chattering notes, as though loudly protesting against this unseemly invasion into his privacy. He is by no means shy, though he usually keeps to the low-growing alders, willows, or whatever other cover there may be, and should we come so close as to disturb him from his shelter, he merely flies on a few yards and recommences his song with redoubled energy. Although rather local in distribution, he is not rare, but is never found except near water, although that water may be only a horsepond surrounded with hawthorn bushes. About the beginning of May, having selected his mate and decided on a spot suitable for a home, family cares will be commenced, and the nest, placed within a foot or two of the ground and well concealed, will be begun. The nest is formed of grass and bents, loosely woven together and lined with finer materials and, occasionally, a few feathers. The eggs, four to six in number, are uniform pale clay brown, sometimes showing mottlings of a darker shade and having a dark hair streak towards the larger end. The young are fed on insects, which form also the chief diet of the parents, though berries are eaten in the season.
Two broods are often reared, and at the end of summer young and old pass away to the tropics. The sexes are alike in plumage, but the female is slightly duller. The upper parts are tawny brown, becoming brighter on the rump and upper tail coverts; the crown is broadly streaked with black, and edged on each side with a broad yellowish-white superciliary stripe. Chin and throat white, breast and under parts buff. Length 5 in.; wing 2·5 in. The young are slightly spotted with brown on the throat.
Generally distributed throughout Great Britain, becoming rarer in the north.
THE AQUATIC WARBLER Acrocephalus aquaticus (J. F. Gmelin)
The Aquatic Warbler is by no means scarce in Europe, but is one of those south-eastern species that extend north-westwards through France and breed sparingly in Holland and Denmark. From recent observations it seems probable that a few examples regularly pass through this country on migration every autumn, but owing to its resemblance to the Sedge Warbler, it has probably often been overlooked.
In general colour it is lighter and paler than the Sedge Warbler, and the wing coverts have broad buffish margins. Its characteristic feature, however, is the conspicuous buff stripe down the middle of the crown. Length 4·9 in.; wing 2·4 in.
THE GRASSHOPPER WARBLER Locustella nævia (Boddært)
Though never very abundant, this skulking species is commoner than is usually supposed. Arriving towards the end of April, its peculiar trilling song, which has earned it many local names, may often be heard. It sounds, however, so much like the noise made by a grasshopper that the bird is frequently unrecognised.
This species is rarely seen, for it loves to remain concealed in the thick undergrowth, either in a compact hedge or in large stretches of sedge and rough grass, but, if we trouble to trace it by its song, we may be lucky enough to see a dark bird moving near the ground with hesitating flight. As it drops after a very short journey into the cover again, we may have time to notice the rounded tail, which is always spread as it settles and is the best clue by which to identify this species on the wing. Approach the spot where he disappeared and you will search in vain, for he has already crept away, and in a few minutes the song will recommence several yards off.
As with all the Warblers, insects form their chief food. The nest, built of grass and bents loosely woven together, is placed low down and well concealed in the rough herbage near the ground, and as the bird seldom flies from it, but creeps silently away on our approach, it is exceedingly difficult to find.
Six eggs form the clutch; the ground colour is whitish, but they are very thickly and uniformly mottled and freckled with reddish brown. The general colour above is greenish brown, each feather having a darker centre. Wings and tail brown, the latter showing faint bars. Under parts brownish, slightly spotted on the throat and breast, darker on the flanks and paler on the belly. The sexes are alike in plumage. Length 5·4 in.; wing 2·4 in.
SAVI'S WARBLER Locustella luscinioides (Savi)
This species was once a regular migrant to certain favoured localities in the East Anglian fens, but subsequent drainage has so affected its haunts that it is no longer to be found there. The last known British specimen was killed over fifty years ago. Possibly a few individuals may sometimes occur on migration, as it still breeds locally in some parts of Holland, but, except for historical interest, it can no longer be included among our British birds.
The sexes are alike, and in size it slightly exceeds that of the preceding species. The upper parts are of a uniform reddish brown, under parts whitish, passing to buff on the breast and flanks. Length 5·7 in.; wing 2·6 in.
THE HEDGE ACCENTOR Accentor modularis (Linnæus)
Of dingy colour, quiet, unobtrusive, yet ever busy, the Hedge Accentor, vulgarly misnamed the "Hedge Sparrow," resembles in his character those among us who are content, even in the bustle of our great cities, to go quietly on their way, doing good wherever they find opportunity and receiving uncomplainingly the kicks which their busier brethren are often only too eager to bestow.
And so it is with the Hedge Sparrow; year in, year out, he is ever with us, quietly and diligently seeking his food along a hedge bottom, on the edge of a coppice, on the garden path, or wherever else he may happen to find himself. He does incalculable good in destroying numbers of noxious insects, and when winter comes, and such food is scarce, he turns his attention to seeds of all kinds, thus helping to keep down many weeds which would otherwise overrun our fields and gardens. Peaceful by nature, he has become very common, and imagining ill of none he is tame, hopping up from the path just in front of us, and disappearing quietly and without sound into the nearest cover, and then, working his way by quiet "creeping hops" (if such an expression be allowable) to the bottom of the bush or hedge, he reappears behind us. We in our turn, it is true, do not often molest him, in fact he is generally ignored and his presence unsuspected, and even when seen, many of us think--"only a sparrow!" and judge him and his acts by those of a race as different from him in habits and qualities as we are from the Chinese!
When he does utter a note, which is towards evening or when suddenly alarmed, it is a short shrill "iss," rather like a pencil being drawn across a slate; his song, which is commenced in March and only carried on during the breeding season, is like his own character, very sweet and unobtrusive, being in fact a low warble, wandering through its inconsecutive measures without any marked phrases or pauses. By early April he will have chosen his mate and the site for his future home, and now and again one may see him having a slight tiff with a neighbour, who may covet his particular nesting-place, but it is nothing serious, for the said neighbour, if defeated, will have his home but a few yards farther on and apparently enjoy possession unmolested.
The nest is a beautiful structure; the foundation is made of twigs and leaves, and the nest itself is of moss, strongly felted together and lined with horsehair; it is perfectly circular in shape and somewhat deep. Here are laid four eggs of a beautiful blue with no spots or blotches to mar the purity of the colour: altogether this little home is in its quiet way one of the most beautiful of our common natural objects; but--"it is only a sparrow," and the passer-by either destroys it or goes on without a thought for our little friend or the beauty of his home. When his mate begins her tedious business of incubation he attends to her wants with unremitting care, bringing her any delicacies in the shape of insects, flies, and caterpillars he can find. The young at first look like balls of down, and when they open bright orange-coloured mouths they are quickly filled with what is apparently a favourite food--luscious green caterpillars. When they leave the nest the young wear a dull mottled brown plumage, and without more ado take their place in the world around, and lead a quiet unobtrusive life near the home where they were bred, till their end comes by some natural means, or till their career for good is suddenly cut off and they are shot as being "only sparrows"!
The sexes are nearly alike, the head, nape, chin, throat, and upper breast are slate grey, rest of the upper parts rufous brown, with darker streaks; flanks brown streaked with darker, belly white. The female is slightly duller. The young are brown, spotted with buff all over. Length 5·5 in.; wing 2·75 in.
This is a numerous species throughout our islands.
THE ALPINE ACCENTOR Accentor collaris (Scopoli)
The Alpine Accentor is an inhabitant of the mountainous regions of Central and Southern Europe, and, like our Hedge Accentor, of very stay-at-home habits, rarely leaving its home until the snow forces it down into the valleys. In England and Wales it has occurred about a dozen times.
In general colour above it is not unlike the preceding species, but the wing coverts are tipped with white, forming a double bar across the wing. Chin and throat white mottled with black, rest of under parts greyish brown, the flanks mottled with chestnut. Length 7 in.; wing 4·1 in.
THE DIPPER Cinclus aquaticus, Bechstein
Wherever a mountain torrent is to be found in these islands we are almost sure to find this bird, as he sits on a boulder which juts out among the rushing water. In shape he resembles the more familiar Wren, but he is essentially a water bird, and seeks most of his food, which consists entirely of aquatic insects and their larvæ, in the bed of the stream.
Diving into the water it reaches the bottom by the aid of both wings and feet, and when there progresses, apparently, by its feet alone.
The nest, placed in the crevice of a wall, often on the under side of a bridge or between two boulders in the centre of the stream, is a large domed structure of moss and leaves, having an elliptical entrance low down on one side.
Four to six dull white eggs form the clutch, and two or three broods are reared in the season, the first eggs being laid early in March. Its song is begun in autumn and continues throughout the winter till well on in spring.
A strictly resident species, this bird may be found in its haunts at all times of the year and is exceedingly common in Scotland, where there are few burns that are not tenanted by two or three pairs. In hard frosty weather, however, when its natural home is frozen and food scarce, it wanders over the country and may at such times be found by tidal ditches on the sea-shore.
Its flight is rapid and direct, and when on the move it almost invariably follows the course of the stream.
