Nature On The Roof

Title:     Nature On The Roof
Author: Richard Jefferies [More Titles by Jefferies]

Increased activity on the housetop marks the approach of spring and summer exactly as in the woods and hedges, for the roof has its migrants, its semi-migrants, and its residents. When the first dandelion is opening on a sheltered bank, and the pale-blue field veronica flowers in the waste corner, the whistle of the starling comes from his favourite ledge. Day by day it is heard more and more, till, when the first green spray appears on the hawthorn, he visits the roof continually. Besides the roof-tree and the chimney-pot, he has his own special place, sometimes under an eave, sometimes between two gables; and as I sit writing, I can see a pair who have a ledge which slightly projects from the wall between the eaves and the highest window. This was made by the builder for an ornament; but my two starlings consider it their own particular possession. They alight with a sort of half-scream half-whistle just over the window, flap their wings, and whistle again, run along the ledge to a spot where there is a gable, and with another note, rise up and enter an aperture between the slates and the wall. There their nest will be in a little time, and busy indeed they will be when the young require to be fed, to and fro the fields and the gable the whole day through; the busiest and the most useful of birds, for they destroy thousands upon thousands of insects, and if farmers were wise they would never have one shot, no matter how the thatch was pulled about.

My pair of starlings were frequently at this ledge last autumn, very late in autumn, and I suspect they had a winter brood there. The starling does rear a brood sometimes in the midst of the winter, contrary as that may seem to our general ideas of natural history. They may be called roof-residents, as they visit it all the year round; they nest in the roof, rearing two and sometimes three broods; and use it as their club and place of meeting. Towards July the young starlings and those that have for the time at least finished nesting, flock together, and pass the day in the fields, returning now and then to their old home. These flocks gradually increase; the starling is so prolific that the flocks become immense, till in the latter part of the autumn in southern fields it is common to see a great elm-tree black with them, from the highest bough downwards, and the noise of their chattering can be heard a long distance. They roost in firs or in osier-beds. But in the blackest days of winter, when frost binds the ground hard as iron, the starlings return to the roof almost every day; they do not whistle much, but have a peculiar chuckling whistle at the instant of alighting. In very hard weather, especially snow, the starlings find it difficult to obtain a living, and at such times will come to the premises at the rear, and at farmhouses where cattle are in the yards, search about among them for insects.

The whole history of the starling is interesting, but I must here only mention it as a roof-bird. They are very handsome in their full plumage, which gleams bronze and green among the darker shades; quick in their motions, and full of spirit; loaded to the muzzle with energy, and never still. I hope none of those who are so good as to read what I have written will ever keep a starling in a cage; the cruelty is extreme. As for shooting pigeons at a trap, it is mercy in comparison.

Even before the starling whistles much, the sparrows begin to chirp: in the dead of winter they are silent; but so soon as the warmer winds blow, if only for a day, they begin to chirp. In January this year I used to listen to the sparrows chirping, the starlings whistling, and the chaffinches' "chink, chink" about eight o'clock, or earlier, in the morning: the first two on the roof; the latter, which is not a roof-bird, in some garden shrubs. As the spring advances, the sparrows sing--it is a short song, it is true, but still it is singing--perched at the edge of a sunny wall. There is not a place about the house where they will not build--under the eaves, on the roof, anywhere where there is a projection or shelter, deep in the thatch, under the tiles, in old eave-swallows' nest. The last place I noticed as a favourite one in towns is on the half-bricks left projecting in perpendicular rows at the sides of unfinished houses, Half a dozen nests may be counted at the side of a house on these bricks; and like the starlings, they rear several broods, and some are nesting late in the autumn. By degrees as the summer advances they leave the houses for the corn, and gather in vast flocks, rivalling those of the starlings. At this time they desert the roofs, except those who still have nesting duties. In winter and in the beginning of the new year, they gradually return; migration thus goes on under the eyes of those who care to notice it. In London, some who fed sparrows on the roof found that rooks also came for the crumbs placed out. I sometimes see a sparrow chasing a rook, as if angry, and trying to drive it away over the roofs where I live, the thief does not retaliate, but, like a thief, flees from the scene of his guilt. This is not only in the breeding season, when the rook steals eggs, but in winter. Town residents are apt to despise the sparrow, seeing him always black; but in the country the sparrows are as clean as a pink; and in themselves they are the most animated, clever little creatures.

They are easily tamed. The Parisians are fond of taming them. At a certain hour in the Tuilleries Gardens, you may see a man perfectly surrounded with a crowd of sparrows--some perching on his shoulder; some fluttering in the air immediately before his face; some on the ground like a tribe of followers; and others on the marble seats. He jerks a crumb of bread into the air--a sparrow dexterously seizes it as he would a flying insect; he puts a crumb between his lips--a sparrow takes it out and feeds from his mouth. Meantime they keep up a constant chirping; those that are satisfied still stay by and adjust their feathers. He walks on, giving a little chirp with his mouth, and they follow him along the path--a cloud about his shoulders, and the rest flying from shrub to shrub, perching, and then following again. They are all perfectly clean--a contrast to the London Sparrow. I came across one of these sparrow-tamers by chance, and was much amused at the scene, which, to any one not acquainted with birds, appears marvellous; but it is really as simple as possible, and you can repeat it for yourself if you have patience, for they are so sharp they soon understand you. They seem to play at nest-making before they really begin; taking up straws in their beaks, and carrying them half-way to the roof, then letting the straws float away; and the same with stray feathers, Neither of these, starlings nor sparrows, seem to like the dark. Under the roof, between it and the first ceiling, there is a large open space; if the slates or tiles are kept in good order, very little light enters, and this space is nearly dark in daylight. Even if chinks admit a beam of light, it is not enough; they seldom enter or fly about there, though quite accessible to them. But if the roof is in bad order, and this space light, they enter freely. Though nesting in holes, yet they like light. The swallows could easily go in and make nests upon the beams, but they will not, unless the place is well lit. They do not like darkness in the daytime.

The swallows bring us the sunbeams on their wings from Africa to fill the fields with flowers. From the time of the arrival of the first swallow the flowers take heart; the few and scanty plants that had braved the earlier cold are succeeded by a constantly enlarging list, till the banks and lanes are full of them. The chimney-swallow is usually the forerunner of the three house-swallows; and perhaps no fact in natural history has been so much studied as the migration of these tender birds. The commonest things are always the most interesting. In summer there is no bird so common everywhere as the swallow, and for that reason many overlook it, though they rush to see a "white elephant." But the deepest thinkers have spent hours and hours in considering the problem of the swallow--its migrations, its flight, its habits; great poets have loved it; great artists and art-writers have curiously studied it. The idea that it is necessary to seek the wilderness or the thickest woods for nature is a total mistake; nature it, at home, on the roof, close to every one. Eave-swallows, or house-martins (easily distinguished by the white bar across the tail), build sometimes in the shelter of the porches of old houses.

As you go in or out, the swallows visiting or leaving their nests fly so closely as almost to brush the face. Swallow means porch-bird, and for centuries and centuries their nests have been placed in the closest proximity to man. They might be called man's birds, so attached are they to the human race. I think the greatest ornament a house can have is the nest of an eave-swallow under the eaves--far superior to the most elaborate carving, colouring, or arrangement the architect can devise. There is no ornament like the swallow's nest; the home of a messenger between man and the blue heavens, between us and the sunlight, and all the promise of the sky. The joy of life, the highest and tenderest feelings, thoughts that soar on the swallow's wings, come to the round nest under the roof. Not only to-day, not only the hopes of future years, but all the past dwells there. Year after year the generations and descent of the swallow have been associated with our homes, and all the events of successive lives have taken place under their guardianship. The swallow is the genius of good to a house. Let its nest, then, stay; to me it seems the extremity of barbarism, or rather stupidity, to knock it down. I wish I could induce them to build under the eaves of this house; I would if I could discover some means of communicating with them.

It is a peculiarity of the swallow that you cannot make it afraid of you; just the reverse of other birds. The swallow does not understand being repulsed, but comes back again. Even knocking the nest down will not drive it away, until the stupid process has been repeated several years. The robin must be coaxed; the sparrow is suspicious, and though easy to tame, quick to notice the least alarming movement. The swallow will not be driven away. He has not the slightest fear of man; he flies to his nest close to the window, under the low eave, or on the beams in the out-houses, no matter if you are looking on or not. Bold as the starlings are, they will seldom do this. But in the swallow the instinct of suspicion is reversed, an instinct of confidence occupies its place. In addition to the eave-swallow, to which I have chiefly alluded, and the chimney-swallow, there is the swift, also a roof-bird, and making its nest in the slates of houses in the midst of towns. These three are migrants in the fullest sense, and come to our houses over thousands of miles of land and sea.

Robins frequently visit the roof for insects, especially when it is thatched; so do wrens; and the latter, after they have peered along, have a habit of perching at the extreme angle of a gable, or the extreme edge of a corner, and uttering their song. Finches occasionally fly up to the roofs of country-houses if shrubberies are near, also in pursuit of insects; but they are not truly roof-birds. Wagtails perch on roofs; they often have their nests in the ivy, or creepers trained against walls; they are quite at borne, and are frequently seen on the ridges of farmhouses. Tits of several species, particularly the great titmouse and the blue tit, come to thatch for insects, both in summer and winter. In some districts where they are common, it is not unusual to see a goatsucker or fern-owl hawk along close to the eaves in the dusk of the evening for moths. The white owl is a roof-bird (though not often of the house), building inside the roof, and sitting there all day in some shaded corner. They do sometimes take up their residence in the roofs of outhouses attached to dwellings, but not often nowadays, though still residing in the roofs of old castles. Jackdaws, again, are roof-birds, building in the roofs of towers. Bats live in roofs, and hang there wrapped up in their membranous wings till the evening calls them forth. They are residents in the full sense, remaining all the year round, though principally seen in the warmer months; but they are there in the colder, hidden away, and if the temperature rises, will venture out and hawk to and fro in the midst of the winter. Tame pigeons and doves hardly come into this paper, but still it is their habit to use roofs as tree-tops. Rats and mice creep through the crevices of roofs, and in old country-houses hold a sort of nightly carnival, racing to and fro under the roof. Weasels sometimes follow them indoors and up to their roof strongholds.

When the first warm days of spring sunshine strike against the southern side of the chimney, sparrows perch there and enjoy it; and again in autumn, when the general warmth of the atmosphere is declining, they still find a little pleasant heat there. They make use of the radiation of heat, as the gardener does who trains his fruit-trees to a wall. Before the autumn has thinned the leaves, the swallows gather on the highest ridge of the roof in a row and twitter to each other; they know the time is approaching when they must depart for another climate. In winter, many birds seek the thatched roofs to roost. Wrens, tits, and even blackbirds roost in the holes left by sparrows or starlings.

Every crevice is the home of insects, or used by them for the deposit of their eggs--under the tiles or slates, where mortar has dropped out between the bricks, in the holes of thatch, and on the straws. The number of insects that frequent a large roof must be very great--all the robins, wrens, bats, and so on, can scarcely affect them; nor the spiders, though these, too, are numerous. Then there are the moths, and those creeping creatures that work out of sight, boring their way through the rafters and beams. Sometimes a sparrow may be seen clinging to the bare wall of the house; tits do the same thing. It is surprising how they manage to hold on. They are taking insects from the apertures of the mortar. Where the slates slope to the south, the sunshine soon heats them, and passing butterflies alight on the warm surface, and spread out their wings, as if hovering over the heat. Flies are attracted in crowds sometimes to heated slates and tiles, and wasps will occasionally pause there. Wasps are addicted to haunting houses, and, in the autumn, feed on the flies. Floating germs carried by the air must necessarily lodge in numbers against roofs; so do dust and invisible particles; and together, these make the rain-water collected in water-butts after a storm turbid and dark; and it soon becomes full of living organisms.

Lichen and moss grow on the mortar wherever it has become slightly disintegrated; and if any mould, however minute, by any means accumulates between the slates, there, too, they spring up, and even on the slates themselves. Tiles are often coloured yellow by such growths. On some old roofs, which have decayed, and upon which detritus has accumulated, wallflowers may be found; and the house-leek takes capricious root where it fancies. The stonecrop is the finest of roof-plants, sometimes forming a broad patch of brilliant yellow. Birds carry up seeds and grains, and these germinate in moist thatch. Groundsel, for instance, and stray stalks of wheat, thin and drooping for lack of soil, are sometimes seen there, besides grasses. Ivy is familiar as a roof-creeper. Some ferns and the pennywort will grow on the wall close to the roof. A correspondent tells me that in Wales he found a cottage perfectly roofed with fern--it grew so thickly as to conceal the roof. Had a painter put this in a picture, many would have exclaimed: "How fanciful! He must have made it up; it could never have grown like that!" Not long after receiving my correspondent's kind letter, I chanced to find a roof near London upon which the same fern was growing in lines along the tiles. It grew plentifully, but was not in so flourishing a condition as that found in Wales. Painters are sometimes accused of calling upon their imagination when they are really depicting fact, for the ways of nature vary very much in different localities, and that which may seem impossible in one place is common enough in another.

Where will not ferns grow? We saw one attached to the under-side of a glass coal-hole cover; its green could be seen through the thick glass on which people stepped daily.

Recently, much attention has been paid to the dust which is found on roofs and ledges at great heights. This meteoric dust, as it is called, consists of minute particles of iron, which are thought to fall from the highest part of the atmosphere, or possibly to be attracted to the earth from space. Lightning usually strikes the roof. The whole subject of lightning-conductors has been re-opened of late years, there being reason to think that mistakes have been made in the manner of their erection. The reason English roofs are high-pitched is not only because of the rain, that it may shoot off quickly, but on account of snow. Once now and then there comes a snow-year, and those who live in houses with flat surfaces anywhere on the roof soon discover how inconvenient they are. The snow is sure to find its way through, damaging ceilings, and doing other mischief. Sometimes, in fine summer weather, people remark how pleasant it would be if the roof were flat, so that it could be used as a terrace, as it is in warmer climates. But the fact is, the English roof, although now merely copied and repeated without a thought of the reason of its shape, grew up from experience of severe winters. Of old, great care and ingenuity--what we should now call artistic skill--were employed in contracting the roof. It was not only pleasant to the eye with its gables, but the woodwork was wonderfully well done. Such roofs may still be seen on ancient mansions, having endured for centuries. They are splendid pieces of workmanship, and seen from afar among foliage, are admired by every one who has the least taste. Draughtsmen and painters value them highly. No matter whether reproduced on a large canvas or in a little woodcut, their proportions please. The roof is much neglected in modern houses; it is either conventional, or it is full indeed of gables, but gables that do not agree, as it were, with each other--that are obviously put there on purpose to look artistic, and fail altogether. Now, the ancient roofs were true works of art, consistent, and yet each varied to its particular circumstances, and each impressed with the individuality of the place and of the designer. The finest old roofs were built of oak or chestnut; the beams are black with age, and, in that condition, oak is scarcely distinguishable from chestnut.

So the roof has its natural history, its science, and art; it has its seasons, its migrants and residents, of whom a housetop calendar might be made. The fine old roofs which have just been mentioned are often associated with historic events and the rise of families; and the roof-tree, like the hearth, has a range of proverbs or sayings and ancient lore to itself. More than one great monarch has been slain by a tile thrown from the housetop, and numerous other incidents have occurred in connection with it. The most interesting is the story of the Grecian mother who, with her infant, was on the roof, when, in a moment of inattention, the child crept to the edge, and was balanced on the very verge. To call to it, to touch it, would have insured its destruction; but the mother, without a second's thought, bared her breast, and the child eagerly turning to it, was saved!
