The field sparrow, as we have seen, prefers neglected old fields overgrown with bushes, but the vesper sparrow chooses more broad, open, breezy, grassy country. When busy picking up insects and seed on the ground, he takes no time for singing, but keeps steadily at work, unlike the vireos that sing between bites. With him music is a momentous matter to which he is quite willing to devote half an hour at a time. He usually mounts to a fence rail or a tree before beginning the repetitions of his lovely, serene vesper which is most likely to be heard about sunset, or at sunrise, if you are not a sleepy-head. Like the rose-breasted grosbeak, he has the delightful habit of singing through the early hours of the summer night. ENGLISH SPARROW Is there a boy or girl in America who does not already know this saucy, keen-witted little gamin who thrives where other birds would starve; who insists upon thrusting himself where he is not wanted, not only in other bird's houses, but about the cornices, pillars, and shutters of our own, where his noise and dirt drive good housekeepers frantic; who, without any weapons but his boldness and impudence to fight with, fears neither man nor beast, and who {115} multiplies as fast as the rabbit, so that he is rapidly inheriting the earth? Even children who have never been out of the slums know at least this one bird, this ever-present nuisance, for he chirps and chatters as cheerfully in the reeking gutters as in the prettiest gardens; he hops with equal calm about the horse's feet and trolley cars in crowded city thoroughfares, as he does about flowery fields and quiet country lanes; he will pick at the overflow from garbage pails on the sidewalk in front of teeming tenements and manure on the city pavements with quite as much relish as he will eat the fresh clean seed spilled by a canary, or cake-crumbs from my lady's hand. Intense cold he endures with cheerful fortitude and as intense mid-summer heat without losing his astonishing vitality. Is it any wonder that a bird so readily adaptable to all sorts of conditions should thrive like a weed and beat his way around the world? Now that he has gained such headway in this country his extermination is practically impossible, since a single pair of sparrows might have 275,716,983,698 descendants in ten years! It is foolish to talk of ridding the land of these vermin of birddom. The conditions that kept them in check at home are lacking in this great land of freedom and so we Americans must pay the penalty for ignorantly tampering with nature. {116}
