At this moment, to tell you true, our meadows and pastures are just thronged8 with skylarks. We have always dozens of them, proclaiming their gladness every sunshiny day in rich cataracts9 of music. But within the last few days the dozens have turned into scores and hundreds, for it is the time of the great influx10 of Continental11 larks over sea into England. There is a difference, too, though a slight one, between our true home birds and the hungry refugees who flock here for food and warmth in winter. Our native and resident skylark is the smaller bird of the two, and more russet in colour; the migrants who join him in our winter fields are both larger and darker. Their ashy isabelline plumage, cold grey granite12 in hue13, has less of a generous rufous tinge14 to relieve it than in the true-born Briton. Such minor15 differences, indeed, between local races of allied16 type occur often in nature; they are the first beginnings out of which new kinds may in time be developed by natural selection. For instance, each important river of Britain has its own breed of salmon17, to be recognized at sight—so they say—by the experienced fly-fisher. Thus, again, in the matter of skylarks, our English type differs slightly in shape and hue from the Continental—just about as much as your John Bull differs from a Frenchman, or a German. As we approach the Mediterranean18, a still paler and lighter19 form begins to take the place of the northern bird, and has been honoured (without due reason, I should think) with a separate Latin name, as a distinct species. It stands to our own ruddy-brown English skylark in something the same relation as the Moor6 or the Syrian stands to the Western European. This pale form, once more, straggles through Anatolia and across Central Asia; but merges20 in the Himalayas, Japan, and China into a russet mountain type, which is also regarded by systematic21 naturalists22 as a distinct species. The truth is, however, when you take any large area of the world together, it is impossible to draw distinct lines anywhere between one animal or plant and another. Kind melts into kind for the most part by imperceptible stages.
Even in the dreariest23 months our skylark still sings to us, at rarer intervals24, on bright frosty mornings. He hovers25 over the grass when it sparkles and scintillates26 with crystal filigree27. His music it is that so endears him to all of us. He is busy at work now, I see, in the stubble of the corn-fields, where, a useful ally of the agricultural interest, he picks out the seeds of black bindweed and corn-poppy—not unmixed, it is true, with occasional grains of wheat or barley28. But he does far more good than harm, for all that. Natives and foreigners live amicably29 side by side, though they do not breed together; for the immigrants, mindful of their Baltic homes, go off again in early spring, leaving the smaller British birds to mate and nest and keep up the true blue blood of the Britannic skylark. While hard weather lasts, the families flock together in large mixed bodies, for mutual30 protection, I suppose, or else for love of companionship; but at the beginning of March they separate and pair, and during this tremulous season of love and courtship their song falls from the clouds still blither and louder and more constant than ever. It showers down upon us with lavish31 profusion32. The male birds rise emulously, singing as they go, and displaying with pride their powers of song and flight before their mates and their rivals. Often they join battle at their giddy height for some coveted33 mate, and fight it out in the sky; she sits demure34 below on the dewy grass meanwhile, watching their deeds of prowess, listening to their bursting hearts, and ready to bestow35 herself, like ladies at a tournament, on the lover who proves himself the stoutest36 and the worthiest37. For we must always remember that those liquid notes which thrill our souls on glad spring mornings have been acquired by the bird, not for our human delight, but as a charm for the ears of his own love-sick partner. For her he modulates38 his swelling39 throat; for her he showers down that fountain spray of melody. Time was when birds had no such musical skill, no such art of courtship; and traces still remain to us in many lands of that more primitive40 period. Just as man is most advanced, most civilized41, most modern in Europe, so birds are most advanced, most developed, most musical of voice in the eastern continent. And just as primitive races linger on in South Africa, Polynesia, the Andaman Islands, to give us some pregnant hint of our own early ancestry42, so more antique and less evolved types of bird linger on in South America and Australia, to show us some relics43 of the primitive winged fauna44 in the days before the sense of song was developed. South American species, belonging to the same great group of perchers as our own sweetest songsters—the nightingale, the thrush, the skylark, the linnet—are not only voiceless, but do not even possess the necessary organs for producing song. European and Asiatic birds, in other words, acquired their singing habits at a later period than the one at which their ancestors parted company for good with their South American relatives. Indeed, it is pleasant for the evolutionist to think that the whole course of the world’s evolution has been in one constant stream towards beauty and sweetness—towards lovelier plumage, daintier spots and dapplings, more graceful45 antlers, more waving crests46, diviner song, intenser colour and scent47 of flowers. The subtlest perfumes belong to the newest types and families of blossom; the mellowest48 notes belong to the newest types and families of birds; the highest beauty belongs to the newest and most spiritual races of civilized humanity. The world, thank God! grows ever more lovely, more pure, more harmonious49.
