se far above the ground their plumage so admirably imitates。
At the far north; travellers have mentioned their inspiriting song; but in the United States we hear only their cheerful twitter。 Nansen tells of seeing an occasional snow bunting in that desolation of arctic ice where the Fram drifted so long。
ROSE…BREASTED GROSBEAK (Habia ludoviciana) Finch family
Length 7。75 to 8。5 inches。 About one…fifth smaller than the robin。 Male Head and upper parts black。 Breast has rose…carmine shield…shaped patch; often extending downward to the centre of the abdomen。 Underneath; tail quills; and two spots on wings white。 Conspicuous yellow; blunt beak。 Female Brownish; with dark streakings; like a sparrow。 No rose…color。 Light sulphur yellow under wings。 Dark brown; heavy beak。 Range Eastern North America; from southern Canada to Panama。 Migrations Early May。 September。 Summer resident。
A certain ornithologist tells with complacent pride of having shot over fifty…eight rose…breasted grosbeaks in less than three weeks (during the breeding season) to learn what kind of food they had in their crops。 This kind of devotion to science may have quite as much to do with the growing scarcity of this bird in some localities as the demands of the milliners; who; however; receive all of the blame for the slaughter of our beautiful songsters。 The farmers in Pennsylvania; who; with more truth than poetry; call this the potato…bug bird; are taking active measures; however; to protect the neighbor that is more useful to their crop than all the insecticides known。 It also eats flies; wasps; and grubs。
Seen upon the ground; the dark bird is scarcely attractive with his clumsy beak overbalancing a head that protrudes with stupid…looking awkwardness; but as he rises into the trees his lovely rose…colored breast and under…wing feathers are seen; and before he has had time to repeat his delicious; rich…voiced warble you are already in love with him。 Vibrating his wings after the manner of the mocking…bird; he pours forth a marvellously sweet; clear; mellow song (with something of the quality of the oriole's; robin's; and thrush's notes); making the day on which you first hear it memorable。 This is one of the few birds that sing at night。 A soft; sweet; rolling warble; heard when the moon is at its full on a midsummer night; is more than likely to come from the rose…breasted grosbeak。
It is not that his quiet little sparrow…like wife has advanced notions of feminine independence that he takes his turn at sitting upon the nest; but that he is one of the most unselfish and devoted of mates。 With their combined efforts they construct only a coarse; unlovely cradle in a thorn…bush or low tree near an old; overgrown pasture lot。 The father may be the poorest of architects; but as he patiently sits brooding over the green; speckled eggs; his beautiful rosy breast just showing above the grassy rim; he is a succulent adornment for any bird's home。
BOBOLINK (Dolichonyx oryzivorus) Blackbird family
Called also:REEDBIRD; MAYBIRD; MEADOW…BIRD; AMERICAN ORTOLAN; BUTTER…BIRD; SKUNK BLACKBIRD
Length 7 inches。 A trifle larger than the English sparrow。 Male In spring plumage: black; with light…yellow patch on upper neck; also on edges of wings and tail feathers。 Rump and upper wings splashed with white。 Middle of back streaked with pale buff。 Tail feathers have pointed tips。 In autumn plumage; resembles female。 Female Dull yellow…brown; with light and dark dashes on back。 wings; and tail。 Two decided dark stripes on top of head。 Range North America; from eastern coast to western prairies。 Migrates in early autumn to Southern States; and in winter to South America and West Indies。 Migrations Early May。 From August to October。 Common summer resident。
Perhaps none of our birds have so fitted into song and story as the bobolink。 Unlike a good child; who should 〃be seen and not heard;〃 he is heard more frequently than seen。 Very shy; of peering eyes; he keeps well out of sight in the meadow grass before entrancing our listening ears。 The bobolink never soars like the lark; as the poets would have us believe; but generally sings on the wing; flying with a peculiar self…conscious flight horizontally thirty or forty feet above the meadow grass。 He also sings perched upon the fence or tuft of grass。 He is one of the greatest poseurs among the birds。
In spring and early summer the bobolinks respond to every poet's effort to imitate their notes。 〃Dignified 'Robert of Lincoln' is telling his name;〃 says one; 〃Spink; spank; spink;〃 another hears him say。 But best of all are Wilson Flagg's lines:
〃。 。 。Now they rise and now they fly; They cross and turn; and in and out; and down the middle and wheel about; With a 'Phew; shew; Wadolincon; listen to me Bobolincon!〃
After midsummer the cares of the family have so worn upon the jollity of our dashing; rollicking friend that his song is seldom heard。 The colors of his coat fade into a dull yellowish brown like that of his faithful mate; who has borne the greater burden of the season; for he has two complete moults each year。
The bobolinks build their nest on the ground in high grass。 The eggs are of a bluish white。 Their food is largely insectivorous: grasshoppers; crickets; beetles; spiders; with seeds of grass especially for variety。
In August they begin their journey southward; flying mainly by night。 Arriving in the Southern States; they become the sad…colored; low…voiced rice or reed bird; feeding on the rice fields; where they descend to the ignominious fate of being dressed for the plate of the epicure。
Could there be a more tragic ending to the glorious note of the gay songster of the north?
BLACKPOLL WARBLER (Dendroica striata) Wood Warbler family
Length 5。5 to 6 inches。 About an inch smaller than the English sparrow。 Male Black cap; cheeks and beneath grayish white; forming a sort of collar; more or less distinct。 Upper parts striped gray; black; and olive。 Breast and under parts white; with black streaks。 Tail olive…brown; with yellow…white spots。 Female Without cap。 Greenish…olive above; faintly streaked with black。 Paler than male。 Bands on wings; yellowish。 Range North America; to Greenland and Alaska。 In winter; to northern part of South America。 Migrations Last of May。 Late October。
A faint 〃screep; screep;〃 like 〃the noise made by striking two pebbles together;〃 Audubon says; is often the only indication of the blackpoll's presence; but surely that tireless bird…student had heard its more characteristic notes; which; rapidly uttered; increasing in the middle of the strain and diminishing toward the end; suggest the shrill; wiry burn of some midsummer insect。 After the opera…glass has searched him out we find him by no means an inconspicuous bird。 A dainty little fellow; with a glossy black cap pulled over his eyes; he is almost hidden by the dense foliage on the trees by the time he returns to us at the very end of spring。 Giraud says that he is the very last of his tribe to come north; though the bay…breasted warbler has usually been thought the bird to wind up the spring procession。
The blackpoll has a certain characteristic motion that distinguishes him from the black…and…white creeper; for which a hasty glance might mistake him; and from the jolly little chickadee with his black cap。 Apparently he runs about the tree…trunk; but in reality he so flits his wings that his feet do not touch the bark at all; yet so rapidly does he go that the flipping wing…motion is not observed。 He is most often seen in May in the apple trees; peeping into the opening blossoms for insects; uttering now and then his slender; lisping; brief song。
Vivacious; a busy hunter; often catching insects on the wing like the flycatchers; he is a cheerful; useful neighbor the short time he spends with us before travelling to the far north; where he mates and nests。 A nest has been found on Slide Mountain; in the Catskills; but the hardy evergreens of Canada; and sometimes those of northern New England; are the chosen home of this little bird that builds a nest of bits of root; lichens; and sedges; amply large for a famil
