In the northern shires birds of some species or another are almost constantly moving about throughout the winter months. Even in inland localities this fact is abundantly apparent to the most casual observer of birds. Rough weather and snow-storms are almost invariably accompanied or heralded by wandering flocks of Lapwings and Larks; Finches and Fieldfares are constantly moving about as the food supply becomes exhausted or inaccessible in various districts; Ducks and other water-fowl change their haunts as frost compels them. We might also here allude to the considerable amount of vertical migration that takes place in the northern shires—that movement between the uplands and the low-lying country and littoral districts, undertaken by such species as Twites, Merlins, Meadow Pipits, Lapwings, Plovers, Curlews, Mallards, and some few other Ducks. This movement has already been described in detail in our accounts of these various species, so it is not necessary to treat with it here at greater length. It is, however, a migrational movement of no small interest, though not a little overlooked by ordinary observers. Thus does the migration of birds progress, in spring and in autumn, across these northern shires, the phenomenon being very similar in its general aspects from year to year. Variety is, however, furnished in the numbers of the several species that so migrate, in the dates of their movements, and also in the occurrences of those abnormal migrants for which these shires have an exceptionally abundant share. We have not space here to chronicle the species that have paid these shires such abnormal visits, but the subject is certainly an interesting one and worthy of passing mention at least.
We propose now to devote the concluding pages of the present chapter to a brief résumé of the various ornithological events that so thickly dot the field-naturalist’s calendar, more especially as they relate to South Yorkshire. There is a great charm about the observation of these events, that from year to year take place in sequence that is as remarkable for its order as for its punctuality; a greater charm even in recording them season after season as the birds unfold their story with the passing months. For a dozen years or more we kept such a record, dealing more especially with the environs of Sheffield; season after season we noted the arrival and departure of the migratory species, the resumption and the cessation of song, the varying food from month to month, the pairing and nest-building, the rearing of the young; the flocking in autumn, the disbanding in spring, the habits of birds at nightfall, their awakening from slumber, their various local movements about the country-side, their actions generally in sunshine and in storm, by daylight and in darkness throughout each month, each week, each day, and not unfrequently each hour of the twenty-four. From a store of notebooks which has accumulated through these long years we will draw our information, that shall carry the story of the birds onwards in a cycle through the months from January to December.
The northern shires are not specially remarkable for avine song during the winter months, and here we have a deficiency that contrasts very strongly with that musical abundance of some of the southern counties. As Waterton remarked long ago, our three best-known perennial choristers are the Robin, the Wren, and the Hedge Accentor, of which trio the first is certainly the most persistent, as it is perhaps the sweetest and most musical, whilst the last is the least so. The Starling, however, is a very fair winter singer. The voice of the Missel-thrush is also heard throughout January, but now and then we have a day perhaps when he is silent, sure sign that music is on the wane. Towards the end of the month the Song Thrushes are back again in their accustomed haunts, and on exceptionally fine and sunny days may be heard to sing a little; the Blackbird, however, is invariably silent. Another irregular singer in January is the Sky-lark. It requires a warm and spring-like day indeed to woo him into voice, still his song must not be overlooked at this season. So far as most birds are concerned, January is a typical winter month. There are few signs among the birds here in South Yorkshire to indicate any change of seasons. At the end of the month Sparrows may be remarked at their old nests, and many Hedge Accentors undoubtedly pair at this time. The Titmice are still leading a nomad life; but the Rook and the Starling seldom fail to visit their nesting-places each morning. The Finches are of course still in flocks, but a rapid abrasion of the pale edges to the feathers is remarkable, sure sign that the nuptial period is now approaching. This is specially the case with Chaffinches and Bramblings: Greenfinches abrade later. Yellow Buntings are still in flocks upon the fields; the Meadow Pipit, yet gregarious, is upon the lowlands. The Moorhen, however, is about to pair; most other of our familiar birds are still displaying characteristics of their winter life.
In February, however, there is a marked change in the habits of many birds, and the few signs of approaching spring rapidly develop themselves. Perhaps these indications are most eloquently expressed in song. During this month the Blackbird regains his voice, irregularly it is true, but the fact is obvious nevertheless. The Song Thrush has now fully regained its matchless varied song; the Sky-lark sings more frequently, and our winter singers are in constant voice. Many Kestrels return to their accustomed summer haunts this month; and the Missel-thrush pairs at the beginning of it. Many Robins also pair; and the Titmice may be heard uttering their love-notes amongst the trees. Starlings are now in pairs; and odd pairs of Sparrows actually commence nesting. March brings still more important changes among the birds, and by many of their ways and movements we read the unerring sign of spring’s approach. Among other things may be mentioned the nest-building of the Rooks, the resumption of song by the Chaffinch and the Yellow Bunting, the flocks of both species now disbanding. Avine song is everywhere on the increase; the Blackbird is getting into finer and more frequent voice, the Hedge Accentor and the Wren are particularly musical; whilst during this month we may find the first nests of the Song Thrush and the Missel-thrush, the Robin and the Hedge Accentor. In the northern shires, however, these early birds not unfrequently suffer for their precocity, and a late fall of snow destroys many nests and eggs. The Dipper is now full of nuptial song, and the Gray Wagtail resorts to the streams where shortly it will rear its young. There is also a considerable migrational movement going on among Pied Wagtails, and Yellow Wagtails in some numbers appear upon the fallows. The Bramblings leave their winter quarters in the shrubberies, and the numbers of the Redwing visibly decline. The first indication of our summer birds of passage is given by some venturesome Chiffchaff or Wheatear; the flocks of Lapwings are dispersing to their breeding-places; so too are the Mallards. March is generally a cold and cheerless month in the south of Yorkshire, and the advance in bird-life is not unfrequently checked by spells of winter weather.
We find abundant recompense for this, however, in the avine changes associated with April. The Missel-thrush now finally becomes mute; but every other singing species is full of song. Now the Yellow Bunting and the Greenfinch are in fine voice, the Sky-lark warbles incessantly, and the avine calendar is punctuated with the note of the Cuckoo once more. Most of our resident birds are now nesting; migrants appear one after the other as the month slips away—Willow Wrens, Whitethroats, Blackcaps, Redstarts, Ring-ouzels, Tree Pipits, Swallows, and Martins among the rest. Grouse are now breeding.

Bird-life in May perhaps reaches the zenith of its activity. It is a month of song and a month of love, during which the nests of nearly all our commoner birds may be found. It also marks the arrival of the last of our summer migrants—the Swift, the Wood Wren, the Flycatcher, the Nightjar, and the Turtle Dove especially. Merlins, Plovers, Twites, and Ring-ouzels are nesting on the moors; Sparrow-hawks and Kestrels in the woods; where also Pheasant, Jay, and Magpie are deep in family cares. Away on the distant coast we also know that sea-fowl are busy too, crowding on sea-cliff and islet, repairing to the sands and shingles, for the sole purpose of reproduction during this and the three succeeding months. Inland bird-life again presents marked changes in June. The Common Sandpiper, which we know came back in April, is now nesting by the side of upland waters; the Nightjar and the Turtle Dove are breeding. One significant fact the chronicler of avine annals will not fail now to remark is the slight cessation in the glorious concert of the woods and fields. There is a decided decrease in song, especially among our earliest breeding birds. Each may and will be heard to warble on every day of June, but certainly not in such abundance as characterized their melody in May. The Cuckoo is also in less splendid voice, and not unfrequently cries in a treble series of notes instead of the normal double one. As birds are notably later here than in south-western counties, we shall also find that June is certainly a more musical month in Yorkshire than it is in Devonshire. With the advent of July, however, the beginning of the end arrives. Thrush, Blackbird, and Robin sing fitfully, as also do the Blackcap and Whitethroat and many others. By the end of the month much song has ceased, Tree Pipits and Chaffinches especially becoming mute. Some birds are still busy with their second or even third broods, but the moulting season is coming on, and that is ever a time of moping and of silence. This month also marks the flocking of many birds, notably the Ring-ouzel, the Rook, the Twite, the Meadow Pipit, the Lapwing, and the Curlew. Tits are also to be seen in family parties, as are also Jays, Magpies, and Starlings. August is much of a repetition of July among our common birds in inland northern districts. Moulting is nearly universal; there is almost a complete cessation of music, and gregarious instincts are becoming stronger. Already some of our summer birds are gone before the middle of the month, especially the Cuckoo and the Swift. Birds now congregate upon the hay-meadows, and vast flocks of Sparrows and other Finches resort to the ripening corn. Migration, of course, is more apparent along the coast; but from time to time, during the stillness of the night, a flock of Waders or Ducks may be detected passing onwards to the south. Towards the close of August the Robin, having passed through his moult, in small numbers regains his song; and the last few days almost invariably reintroduce us to the glad wild lay of the Missel-thrush. The Wren is a very irregular singer yet; but the Starling resumes his music, whilst the Yellow Bunting and the Greenfinch during the first fortnight lose theirs for the winter. The Chiffchaff also is an irregular singer during August.
In September we have migration once more in full progress. Day by day our summer visitors are now deserting us; birds that spend the winter gregarious are closing up fast into flocks; Pipits, Twites, and other moorland species come down to the lowland fields; the Swallows and Martins congregate into those vast companies that invariably herald their departure. Song Thrushes in great numbers frequent the turnip-fields, as also do Meadow Pipits and Hedge Accentors; by the end of the month Missel-thrushes are in flocks upon the fields, as also are Starlings and Sparrows. Now the Ring-ouzels speed away to the south, and the Blackbird shows a far too unwelcome partiality for the fruit-garden. All the Warblers are migrating fast; the Rooks and Jays complete their moult, as also do the Chaffinch, the Redpole, and the Yellow Bunting. October, nut-brown October, finally clears away the last of our summer visitors, and brings us bird guests from the far north-east. One of the most familiar of these is the Redwing; they return with pleasing regularity to their old haunts. Now the coppices begin to swarm with migrant Goldcrests and Titmice; the Merlins leave the moors finally for the winter; a few Fieldfares come to us; the Stonechat quits the moorland roughs; the parties of Jays disband; flocks of Finches resort to the stubbles; the Yellow Bunting is gregarious once more; many of the Red Grouse resort to the highest parts of the moors; Pheasants are still moulting; Woodcocks and Jack Snipes appear in their accustomed winter haunts. On every side are indications of avine habits and movements characteristic of winter. The Robin, the Wren, and the Missel-thrush are now in charming voice, but the Starling is only an occasional singer, as is also the Sky-lark.
