After the middle of June the common began to attract me more and more. It was so extensive that, standing on its border, just beyond the last straggling cottages and orchards, the further side was seen only as a line of blue trees, indistinct in the distance. As I grew to know it better, adding each day to my list from its varied bird life, the woods and waterside were visited less and less frequently, and after the bird-scaring noises began in the village, its wildness and quiet became increasingly grateful. The silence of nature was broken only by bird sounds, and the most frequent sound was that of the yellow bunting, as, perched motionless on the summit of a gorse bush, his yellow head conspicuous at a considerable distance, he emitted his thin monotonous chant at regular intervals, like a painted toy-bird that sings by machinery. There, too, sedentary as an owl in the daytime, the corn bunting was common, discharging his brief song at intervals--a sound as of shattering glass. The whinchat was rarely seen, but I constantly met the small, prettily coloured stonechat flitting from bush to bush, following me, and never ceasing his low, querulous tacking chirp, anxious for the safety of his nest. Nightingales, blackcaps and white-throats also nested there, and were louder and more emphatic in their protests when approached. There were several grasshopper-warblers on the common, all, very curiously as it seemed to me, clustered at one spot, so that one could ramble over miles of ground without hearing their singular note; but on approaching the place they inhabited one gradually became conscious of a mysterious trilling buzz or whirr, low at first and growing louder and more stridulous, until the hidden singers were left behind, when by degrees it sank lower and lower again, and ceased to be audible at a distance of about one hundred yards from the points where it had sounded loudest. The birds hid in clumps of furze and bramble so near together that the area covered by the buzzing sound measured about two hundred yards across. This most singular sound (for a warbler to make) is certainly not ventriloquial, although if one comes to it with the sense of hearing disorganized by town noises or unpractised, one is at a loss to determine the exact spot it comes from, or even to know from which side it comes. While emitting its prolonged sound the bird is so absorbed in its own performance that it is not easily alarmed, and will sometimes continue singing with a human listener standing within four or five yards of it. When one is near the bird, and listens, standing motionless, the effect on the nerves of hearing is very remarkable, considering the smallness of the sound, which, without being unpleasant, is somewhat similar to that produced by the vibration of the brake of a train; it is not powerful enough to jar the nerves, but appears to pervade the entire system.
