Watching the line of the hedge, about every two minutes, either near at hand or yonder a bird darts out just at the level of the grass, hovers a second with labouring wings, and returns as swiftly to the cover. Sometimes it is a flycatcher, sometimes a greenfinch, or chaffinch, now and then a robin, in one place a shrike, perhaps another is a redstart. They are fly-fishing all of them, seizing insects from the sorrel tips and grass, as the kingfisher takes a roach from the water. A blackbird slips up into the oak and a dove descends in the corner by the chestnut tree. But these are not visible together, only one at a time and with intervals. The larger part of the life of the hedge is out of sight. All the thrush-fledglings, the young blackbirds, and finches are hidden, most of them on the mound among the ivy, and parsley, and rough grasses, protected too by a roof of brambles. The nests that still have eggs are not, like the nests of the early days of April, easily found; they are deep down in the tangled herbage by the shore of the ditch, or far inside the thorny thickets which then looked mere bushes, and are now so broad. Landrails are running in the grass concealed as a man would be in a wood; they have nests and eggs on the ground for which you may search in vain till the mowers come. Up in the corner a fragment of white fur and marks of scratching show where a doe has been preparing for a litter. Some well-trodden runs lead from mound to mound; they are sandy near the hedge where the particles have been carried out adhering to the rabbits' feet and fur. A crow rises lazily from the upper end of the field, and perches in the chestnut. His presence, too, was unsuspected. He is there by far too frequently. At this season the crows are always in the mowing-grass, searching about, stalking in winding tracks from furrow to furrow, picking up an egg here and a foolish fledgling that has wandered from the mound yonder. Very likely there may be a moorhen or two slipping about under cover of the long grass; thus hidden, they can leave the shelter of the flags and wander a distance from the brook. So that beneath the surface of the grass and under the screen of the leaves there are ten times more birds than are seen.
