s rolling tattoo in spring on some resonant limb under our windows in the garden with a strength worthy of a larger drummer。
This rolling tattoo； or drumming； answers several purposes： by it he determines whether the tree is green or hollow； it startles insects from their lurking places underneath the bark； and it also serves as a love song。
YELLOW…BELLIED WOODPECKER （Sphyrapicus varius） Woodpecker family
Called also： THE SAPSUCKER； ＇YELLOW…BELLIED SAPSUCKER； AOU 1998＇
Length 8 to 8。6 inches。 About one…fifth smaller than the robin。 Male Black； white； and yellowish white above； with bright…red crown； chin； and throat。 Breast black； in form of crescent A yellowish…white line； beginning at bill and passing below eye； merges into the pale yellow of the bird underneath。 Wings spotted with white； and coverts chiefly white。 Tail black； white on middle of feathers。 Female Paler； and with head and throat white。 Range Eastern North America； from Labrador to Central America。 Migrations April。 October。 Resident north of Massachusetts。 Most common in autumn。
It is sad to record that this exquisitely marked woodpecker； the most jovial and boisterous of its family； is one of the very few bird visitors whose intimacy should be discouraged。 For its useful appetite for slugs and insects which it can take on the wing with wonderful dexterity； it need not be wholly condemned。 But as we look upon a favorite maple or fruit tree devitalized or perhaps wholly dead from its ravages； we cannot forget that this bird； while a most abstemious fruit…eater； has a pernicious and most intemperate thirst for sap。 Indeed； it spends much of its time in the orchard； drilling holes into the freshest； most vigorous trees； then； when their sap begins to flow； it siphons it into an insatiable throat； stopping in its orgie only long enough to snap at the insects that have been attracted to the wounded tree by the streams of its heart…blood now trickling down its sides。 Another favorite pastime is to strip the bark off a tree； then peck at the soft wood underneath almost as fatal a habit。 It drills holes in maples in early spring for sap only。 If it drills holes in fruit trees it is for the cambium layer； a soft； pulpy； nutritious under…bark。
These woodpeckers have a variety of call…notes； but their rapid drumming against the limbs and trunks of trees is the sound we always associate with them and the sound that Mr。 Bicknell says is the love…note of the family。
Unhappily； these birds； that many would be glad to have decrease in numbers； take extra precautions for the safety of their young by making very deep excavations for their nests； often as deep as eighteen or twenty inches。
THE CHEWINK （Pipilo erythrophthalmus） Finch family
Called also： GROUND ROBIN； TOWHEE； TOWHEE BUNTING； TOWHEE GROUND FINCH； GRASEL； ＇EASTERN TOWHEE； AOU 1998＇
Length 8 to 8。5 inches。 About one…fifth smaller than the robin。 Male Upper parts black； sometimes margined with rufous。 Breast white； chestnut color on sides and rump。 Wings marked with white。 Three outer feathers of tail striped with white； conspicuous in flight。 Bill black and stout。 Red eyes； feet brown。 Female Brownish where the male is black。 Abdomen shading from chestnut to white in the centre。 Range From Labrador； on the north； to the Southern States； West to the Rocky Mountains。 Migrations April。 September and October。 Summer resident。 Very rarely a winter resident at the north。
The unobtrusive little chewink is not infrequently mistaken for a robin； because of the reddish chestnut on its under parts。 Careful observation； however； shows important distinctions。 It is rather smaller and darker in color； its carriage and form are not those of the robin； but of the finch。 The female is smaller still； and has an olive tint in her brown back。 Her eggs are inconspicuous in color； dirty white speckled with brown； and laid in a sunken nest on the ground。 Dead leaves and twigs abound； and form； as the anxious mother fondly hopes； a safe hiding place for her brood。 So careful concealment； however； brings peril to the fledglings； for the most cautious bird…lover may； and often does； inadvertently set his foot on the hidden nest。
The chewink derives its name from the fancied resemblance of its note to these syllables； while those naming it 〃towhee〃 hear the sound to…whick； to…whick； to…whee。 Its song is rich； full； and pleasing； and given only when the bird has risen to the branches above its low foraging ground。
It frequents the border of swampy places and bushy fields。 It is generally seen in the underbrush； picking about among the dead leaves for its steady diet of earthworms and larvae of insects； occasionally regaling itself with a few dropping berries and fruit。
When startled； the bird rises not more than ten or twelve feet from the earth； and utters its characteristic calls。 On account of this habit of flying low and grubbing among the leaves； it is sometimes called the ground robin。 In the South our modest and useful little food…gatherer is often called grasel； especially in Louisiana； where it is white…eyed； and is much esteemed； alas！ by epicures。
SNOWFLAKE （Plectrophenax nivalis） Finch family
Called also： SNOW BUNTING ＇AOU 1998＇； WHITEBIRD； SNOWBIRD； SNOW LARK
Length 7 to 7。5 inches。 About one…fourth smaller than the robin。 Male and Female Head； neck； and beneath soiled white； with a few reddish…brown feathers on top of head； and suggesting an imperfect collar。 Above； grayish brown obsoletely streaked with black； the markings being most conspicuous in a band between shoulders。 Lower tail feathers black； others； white and all edged with white。 Wings brown； white； and gray。 Plumage unusually variable。 In summer dress （in arctic regions） the bird is almost white。 Range Circumpolar regions to Kentucky （in winter only）。 Migrations Midwinter visitor； rarely； if ever； resident south of arctic regions。
These snowflakes （mentioned collectively； for it is impossible to think of the bird except in great flocks） are the 〃true spirits of the snowstorm；〃 says Thoreau。 They are animated beings that ride upon it； and have their life in it。 By comparison with the climate of the arctic regions； no doubt our hardiest winter weather seems luxuriously mild to them。 We associate them only with those wonderful midwinter days when sky； fields； and woods alike are white； and a 〃hard； dull bitterness of cold〃 drives every other bird and beast to shelter。 It is said they often pass the night buried beneath the snow。 They have been seen to dive beneath it to escape a hawk。
Whirling about in the drifting snow to catch the seeds on the tallest stalks that the wind in the open meadows uncovers； the snowflakes suggest a lot of dead leaves being blown through the all…pervading whiteness。 Beautiful soft brown； gray； and predominating black…and…white coloring distinguish these capricious visitors from the slaty junco； the 〃snowbird〃 more commonly known。 They are； indeed； the only birds we have that are nearly white； and rarely； if ever； do they rise 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； ro
