At the outside of the withies, where the earth is drier, stand tall horse-chestnut trees, aspen, and beech. The leaflets of the horse-chestnut are already opening; but on the ground, half-hidden under beech leaves not yet decayed, and sycamore leaves reduced to imperfect grey skeletons, there lies a chestnut shell. It is sodden, and has lost its original green—the prickles, too, have decayed and disappeared; yet at a touch it falls apart, and discloses two chestnuts, still of a rich, deep polished brown.
On the very bank of the brook there grows a beech whose bare boughs droop over, almost dipping in the water, where it comes with a swift rush from the narrow arches of a small bridge whose bricks are green with moss. The current is still slightly turbid, for the floods have not long subsided, and the soaked meadows and ploughed fields send their rills to swell the brook and stain it with sand and earth. On the surface float down twigs and small branches forced from the trees by the gales: sometimes an entangled mass of aquatic weeds—long, slender green filaments twisted and matted together—comes more slowly because heavy and deep in the water.
A little bird comes flitting silently from the willows and perches on the drooping beech branch. It is a delicate little creature, the breast of a faint and dull yellowy green, the wings the lightest brown, and there is a pencilled streak over the eye. The beak is so slender it scarce seems capable of the work it should do, the legs and feet so tiny that they are barely visible. Hardly has he perched than the keen eyes detect a small black speck that has just issued from the arch, floating fast on the surface of the stream and borne round and round in a tiny whirlpool.
He darts from the branch, hovers just above the water, and in a second has seized the black speck and returned to the branch. A moment or two passes, and again he darts and takes something—this time invisible—from the water. A third time he hovers, and on this occasion just brushes the surface. Then, suddenly finding that these movements are watched, he flits—all too soon—up high into the beech and away into the narrow copse. The general tint and shape of the bird are those of the willow wren, but it is difficult to identify the species in so brief a glance and without hearing its note.
The path now trends somewhat away from the stream and skirts a ploughed field, where the hedges are cropped close and the elms stripped of the lesser boughs about the trunks, that the sparrows may not find shelter. But all the same there are birds here too—one in the thick low hedge, two or three farther on, another in the ditch perching on the dead white stems of last year’s plants that can hardly support an ounce weight, and all calling to each other. It is six marsh tits, as busy as they can well be.
One rises from the ditch to the trunk of an elm where the thick bark is green with lichen: he goes up the tree like a woodpecker, and peers into every crevice. His little beak strikes, peck, peck, at a place where something is hidden: then he proceeds farther up the trunk: next he descends a few steps in a sidelong way, and finally hops down some three inches head foremost, and alights again on the all but perpendicular bark. But his tail does not touch the tree, and in another minute down he flies again to the ditch.
A shrill and yet low note that sounds something like “skeek-skeek” comes from a birch, and another “skeek-skeek” answers from an elm. It is like the friction of iron against iron without oil on the bearings. This is the tree-climber calling to his mate. He creeps over the boles of the birch, and where the larger limbs join the trunk, trailing his tail along the bark, and clinging so closely that but for the sharp note he would be passed. Even when that has called attention, the colour of his back so little differs from the colour of bark that if he is some height up the tree it is not easy to detect him.
The days go on and the hedges become green—the sun shines, and the blackbirds whistle in the trees. They leave the hedge, and mount into the elm or ash to deliver their song; then, after a pause, dive down again to the bushes. Up from the pale green corn that is yet but a few inches high rises a little brown bird, mounting till he has attained to the elevation of the adjacent oak. Then, beginning his song, he extends his wings, lifts his tail, and gradually descends slanting forward—slowly, like a parachute—sing, sing, singing all the while till the little legs, that can be seen against the sky somewhat depending, touch the earth and the wheat hides him. Still from the clod comes the finishing bar of his music.
In a short time up he rises again, and this time from the summit of his flight sinks in a similar manner singing to a branch of the oak. There he sings again; and, again rising, comes back almost to the same bough singing as he descends. But he is not alone: from an elm hard by come the same notes, and from yet another tree they are also repeated. They cannot rest—now one flits from the topmost bough of an elm to another topmost bough; now a second comes up from feeding, and cries from the branches. They are tree-pipits; and though the call is monotonous, yet it is so cheerful and pleasing that one cannot choose but stay and listen.
Suddenly, two that have been vigorously calling start forward together and meet in mid-air. They buffet each other with their wings; their little beaks fiercely strike; their necks are extended; they manoeuvre round each other, trying for an advantage. They descend, heedless in the rage of their tiny hearts, within a few yards of the watcher, and then in alarm separate. But one flies to the oak branch and defiantly calls immediately.
