s; northern United States; occasional in Middle States; abundant in winter as far as Kansas and the Rocky Mountains。 Migrations Winter visitors; rarely resident; and without a Fixed season。
This arctic bird; although considered somewhat rare with us; when seen at all in midwinter is in such large flocks that; before its visit in the neighborhood is ended; and because there are so few other birds about; it becomes delightfully familiar as it nimbly runs over the frozen ground; picking up grain that has blown about from the barn; when the seeds of the field are buried under snow。 This lack of fear through sharp hunger; that often drives the shyest of the birds to our very doors in winter; is as pathetic as it is charming。 Possibly it is not so rare a bird as we think; for it is often mistaken for some of the sparrows; the shore larks; and the snow buntings; that it not only resembles; but whose company it frequently keeps; or for one of the other longspurs。
At all seasons of the year a ground bird; you may readily identify the Lapland longspur by its tracks through the snow; showing the mark of the long hind claw or spur。 In summer we know little or nothing about it; for; with the coming of the flowers; it is off to the far north; where; we are told; it depresses its nest in a bed of moss upon the ground; and lines it with fur shed from the coat of the arctic fox。
CHIPPING SPARROW (Spizella socialis) Finch family
Called also: CHIPPY; HAIR…BIRD; CHIP…BIRD; SOCIAL SPARROW
Length 5 to 5。5 inches。 An inch shorter than the English sparrow。 Male Under the eye; on the back of the neck; underneath; and on the lower back ash…gray。 Gray stripe over the eye; and a blackish brown one apparently through it。 Dark red…brown crown。 Back brown; slightly rufous; and feathers streaked with black。 Wings and tail dusty brown。 Wing…bars not conspicuous。 Bill black。 Female Lacks the chestnut color on the crown; which is Streaked with black。 In winter the frontlet is black。 Bill brownish。 Range North America; from Newfoundland to the Gulf of Mexico And westward to the Rockies。 Winters in Gulf States and Mexico。 Most common in eastern United States。 Migrations April。 October。 Common summer resident; many birds remaining all the year from southern New England southward。
Who does not know this humblest; most unassuming little neighbor that comes hopping to our very doors; this mite of a bird with 〃one talent〃 that it so persistently uses all the day and every day throughout the summer? Its high; wiry trill; like the buzzing of the locust; heard in the dawn before the sky grows even gray; or in the middle of the night; starts the morning chorus; and after all other voices are hushed in the evening; its tremolo is the last bed…song to come from the trees。 But however monotonous such cheerfulness sometimes becomes when we are surfeited with real songs from dozens of other throats; there are long periods of midsummer silence that it punctuates most acceptably。
Its call…note; chip! chip! from which several of its popular names are derived; is altogether different from the trill which must do duty as a song to express love; contentment; everything that so amiable a little nature might feel impelled to voice。
But with all its virtues; the chippy shows lamentable weakness of character in allowing its grown children to impose upon it; as it certainly does。 In every group of these birds throughout the summer we can see young ones (which we may know by the black line…stripes on their breasts) hopping around after their parents; that are often no larger or more able…bodied than they; and teasing to be fed; drooping their wings to excite pity for a helplessness that they do not possess when the weary little mother hops away from them; and still persistently chirping for food until she weakly relents; returns to them; picks a seed from the ground and thrusts it down the bill of the sauciest teaser in the group。 With two such broods in a season the chestnut feathers on the father's jaunty head might well turn gray。
Unlike most of the sparrows; the little chippy frequents high trees; where its nest is built quite as often as in the low bushes of the garden。 The horse…hair; which always lines the grass〃 up that holds its greenish…blue; speckled eggs; is alone responsible for the name hair…bird; and not the chippy's hair…like trill; as some suppose。
ENGLISH SPARROW (Passer domesticus) Finch family
Called also: HOUSE SPARROW 'AOU 1998'
Length 6。33 inches。 Male Ashy above; with black and chestnut stripes on back and shoulders。 Wings have chestnut and white bar; bordered by faint black line。 Gray crown; bordered from the eye backward and on the nape by chestnut。 Middle of throat and breast black。 Underneath grayish white。 Female Paler; wing…bars indistinct; and without the black marking on throat and breast。 Range Around the world。 Introduced and naturalized in America; Australia; New Zealand。 Migrations Constant resident。
〃Of course; no self…respecting ornithologist will condescend to enlarge his list by counting in the English sparrow too pestiferous to mention;〃 writes Mr。 H。 E。 Parkhurst; and yet of all bird neighbors is any one more within the scope of this book than the audacious little gamin that delights in the companion ship of humans even in their most noisy city thoroughfares?
In a bulletin issued by the Department of Agriculture it is shown that the progeny of a single pair of these sparrows might amount to 275;716;983;698 in ten years! Inasmuch as many pairs were liberated in the streets of Brooklyn; New York; in 1851; when the first importation was made; the day is evidently not far off when these birds; by no means meek; 〃shall inherit the earth。〃
In Australia Scotch thistles; English sparrows; and rabbits; three most unfortunate importations; have multiplied with equal rapidity until serious alarm fills the minds of the colonists。 But in England a special committee appointed by the House of Commons to investigate the character of the alleged pest has yet to learn whether the sparrow's services as an insect…destroyer do not outweigh the injury it does to fruit and grain。
FIELD SPARROW (Spizella pusilla) Finch family
Called also: FIELD BUNTING; WOOD SPARROW; BUSH SPARROW
Length 5。5 to 5。75 inches。 A little smaller than the English sparrow。 Male Chestnut crown。 Upper back bright chestnut; finely streaked with black and ashy brown。 Lower back more grayish。 Whitish wing…bars。 Cheeks; line over the eye; throat; pale brownish drab。 Tail long。 Underneath grayish white; tinged with palest buff on breast and sides。 Bill reddish。 Female Paler; the crown edged with grayish。 Range North America; from British provinces to the Gulf; and westward to the plains。 Winters from Illinois and Virginia southward。 Migrations April。 November。 Common summer resident。
Simply because both birds have chestnut crowns; the field sparrow is often mistaken for the dapper; sociable chippy; and; no doubt because it loves such heathery; grassy pastures as are dear to the vesper sparrow; and has bay wings and a sweet song; these two cousins also are often confused。 The field sparrow has a more reddish…brown upper back than any of its small relatives; the absence of streaks on its breast and of the white tail quills so conspicuous in the vesper sparrow's flight; sufficiently differentiate the two birds; while the red bill of the field sparrow is a positive mark of identification。
This bird of humble nature; that makes the scrubby pastures and uplands tuneful from early morning until after sunset; flies away with exasperating shyness as you approach。 Alighting on a convenient branch; he lures you on with his clear; sweet song。 Follow him; and he only hops about from bush to bush; farther and farther away; singing as he goes a variety of strains; which is one of the bird's peculiarities。 The song not only varies in individuals; but in different localities; which may be one reason why no two ornithologists record it alike。 Doubtless the chief reason for the amusing differences in the syllables into which the songs of birds are often translated in the books; is that the same Notes actually sound differently to different individuals。 Thus; to people in Massachusetts the white…throated sparrow seems to say; 〃Pea…bod…y; Pea…bod…y; Pea…bod…y!〃 while good British subjects beyond the New England border hear him sing quite distinctly; 〃Sweet Can…a…da; Can…a…da; Can…a…da!〃 But however the opinions as to the syllables of the field sparrow's song may differ; all are agreed as to its exquisite quality; that resembles the vesper sparrow's tender; sweet melody。 The song begins with three soft; wild whistles; and ends with a series of trills and quavers that gradually melt away into silence: a serene and restful strain as soothing as a hymn。 Like the vesper sparrows; these birds sometimes build a plain; grassy nest; unprotected by over hanging bush; flat upon the ground。 Possibly from a prudent tear of field…mice and snakes; the little mother most frequently lays her bluish…white; rufous marked eggs in a nest placed in a bush of a bushy field。 Hence John Burroughs has called the bird the '
