DIRECTIONS FOR WRITTEN WORK
Have the children give anecdotes about birds that they have observed. Let them describe actions which they saw them perform, paying particular attention to the ways of birds in eating. For example, sparrows were observed carrying hard crusts of bread to a little pool of water, formed in a dent in a tin roof, to soften before attempting to eat them. Day after day crusts were put out, and the water was renewed.
Written descriptions of birds feeding their young.—Young birds live entirely upon insect life. It has been computed that a bird during the first few weeks of its life consumes nearly one and one half times its weight of insects daily. Note the amazing amount of insect life that will be destroyed by the birds of a neighborhood in a single season. Give, if possible, illustrations from your own observation. A robin was noticed feeding one of its young, which sat on a limb with its mouth open, crying for more, except when it was stopped with food. The parent came with her beak filled with worms twenty-seven times in less than as many minutes, and then left her child seemingly as hungry as ever, for he complained and hopped along the limb, keeping a sharp lookout for several minutes. That chick must have been as full of worms as a fisherman's bait-box. Picture the condition of our lawns, gardens, and groves if all the birds were suddenly banished and the insects held full sway. In this connection, the writer should study and make quotations or abstracts from "The Birds of Killingworth," by Longfellow.
In a recent lecture, Prof. Witmer Stone, of Philadelphia, cited many facts to show that birds are nature's great check on the excess of insects, and that they keep the balance between plants and insect life. Ten thousand caterpillars, it has been estimated, could destroy every blade of grass on an acre of cultivated ground. In thirty days from the time it is hatched an ordinary caterpillar increases 10,000 times in bulk, and the food it lives and grows on is vegetable. The insect population of a single cherry tree infested with aphides was calculated by a prominent entomologist at no less than twelve million. The bird population of cultivated country districts has been estimated at from seven hundred to one thousand per square mile. This is small compared with the number of insects, yet as each bird consumes hundreds of insects every day, the latter are prevented from becoming the scourge they would be but for their feathered enemies.
Mr. E. H. Forbush, Ornithologist of the Board of Agriculture of Massachusetts, states that the stomachs of four chickadees contained 1,028 eggs of the cankerworm. The stomachs of four other birds of the same species contained about 600 eggs and 105 female moths of the cankerworm. The average number of eggs found in twenty of these moths was 185; and as it is estimated that a chickadee may eat thirty female cankerworm moths per day during the twenty-five days which these moths crawl up trees, it follows that in this period each chickadee would destroy 138,750 eggs of this noxious insect.
A pamphlet issued by the Department of Agriculture of the United States says that the cuckoo, which is common in all the Eastern States, has been conclusively shown to be much given to eating caterpillars, and, unlike most birds, does not reject those that are covered with hair. In fact, cuckoos eat so many hairy caterpillars that the hairs pierce the inner lining of their stomach and remain there, so that when the stomach is opened and turned inside out, it appears to be lined with a thin coating of hair. This bird also eats beetles, grasshoppers, sawflies, and spiders. It turns out from the investigations of the department that the suspicion with which all farmers look upon woodpeckers is undeserved by that bird. These birds rarely leave an important mark upon a healthy tree, but when a tree is affected by wood-boring larvæ the insects are accurately located, dislodged, and devoured. In case the holes from which the borers are taken are afterward occupied and enlarged by colonies of ants, these ants are drawn out and eaten. Woodpeckers are great conservators of forests, and to them more than to any other agency is due the preservation of timber from hordes of destructive insects.
The department defends the much-abused crow and states that he is not by any means the enemy of the farmer, in which rôle he is generally represented. The pamphlet shows that he is known to eat frogs, toads, salamanders, and some small snakes, and that he devours May beetles, June bugs, grasshoppers, and a large variety of other destructive insects. It is admitted that he does some damage to sprouting corn, but this can be prevented by tarring the seed, which not only saves the corn, but forces the crow to turn his attention to insects.
Insects injurious to vegetation.—Essays may be written describing some of the insects injurious to fruit trees; also the birds that feed largely upon these insects—the warblers, thrushes, orioles, wrens, woodpeckers, vireos, and others. Tell, if possible, from your own observation, of their curious, but effective, ways of finding their food. Describe how the birds inspect the trees, limb by limb and bud by bud, in their eager search for the eggs, larvæ, and mature forms of insects. Note, especially, the oriole as he runs spirally round a branch to the very tip, then back to the trunk, treating branch after branch in the same way, till the whole tree has been thoroughly searched, almost every bud having been in the focus of those bright eyes. It is hard to describe which is the more beautiful—their brilliant, flaming colors or their bugle-like bursts of music. Is the woodpecker's drumming, and apparent listening with the side of his head turned to the tree, all for fun, and nothing for reward?
Birds that feed upon the potato beetle.—The grosbeaks and the tanagers. Describe these. Why are these and other brightly colored birds so shy? What has been the effect of the extensive killing of them for ornament, and the equally cruel practice of securing their young to be kept in cages? Note how much more attractive our fields and gardens would be if these beautiful beings were common in them, and by their quaint ways were "teaching us manners."
Personations of birds.—Ask the children to write "personations" of birds, as if the writer were the bird. Give them the following directions: Write in the first person. Describe yourself as accurately as you are able, without telling your name. Tell of your habits and manner of life, your summer and winter homes, your home cares—your nest building, your parental joys and anxieties, the enemies you have to avoid. Mention at some length the trouble you take to give your little ones a good start in life, and to enable them to earn their own living. Describe your songs, and try to indicate why they differ, and what you mean by each one. Try to present a somewhat complete picture of the bird and its life, from the bird's point of view. At the close of your personation the hearers may vote upon the name of the bird presented.
A family of birds may also be described, as if they were persons,—and are they not? A very fine model of this kind of work is "Our New Neighbors at Ponkapog," by T. B. Aldrich.
Have essays written upon the following subjects:—
Are there birds that do not sing?
What is the attitude of other birds to the owl?
Is any country too cold, or any too warm, for birds?
Have birds individuality?
What is the largest bird of North America?
The smallest?
What laws has your state made about birds?
Ought the "government to own" the birds? (That is, make laws for their protection.)
Is the blue jay wicked?
What birds walk?
Do birds travel at night, during their migrations?
Beginning in March, note for several days the different kinds of birds you see, which were not seen the day before. Make at least two observations daily, one in the morning and one after school. When is the greater number of new birds seen, in the morning or in the afternoon? Or, if you live in a comparatively quiet neighborhood, even in a large city, go out at night and listen for bird sounds in the air. You need not go far to make this trial—your own back door "opens into all outdoors."
What states have established a Bird Day by law?
Is woman cruel or only thoughtless?
Do robins raise more than one brood in a season? If so, do they use the same nest twice? If they raise two broods, what becomes of the first, while the mother is sitting upon the eggs for the second?
Watch for a robin leading out his family. Notice the feeding, after the birds are large enough to run and fly fairly well. The young birds are placed apart, and kept apart by the parent, who visits each one in turn, and rebukes any who tries to be piggish, sometimes rapping it with his bill when it runs out of turn. Notice this parent teaching the young to sing. It is a very interesting sight.
What birds have you heard sing at night?
More birds sing at night than is commonly supposed. The female robin calls to her mate frequently during the night, and he responds with a song. The catbird also sings at night. Last May one was heard to sing three nights in succession from eleven o'clock until daylight in response to little complaining calls from his mate. The song sparrow, warblers, and many other birds sing at night. Their songs at these times sound as if the bird were sleepy and reluctant to sing, or as if he were startled and were hurrying through the performance. Make a note of songs heard at night and try to determine the cause. Learn to distinguish the call of the female from the song of the male.
The kinds of nests.—What birds are weavers? What ones are masons or plasterers? What ones are tailors, in the construction of their nests?
Find a pair of birds engaged in nest building; robins may generally be found. Learn to distinguish the male from the female in appearance, as well as voice. Notice what materials they are using. Which bird takes the lead in building? What does the other bird do? Does he ever carry material, or does he simply act as escort? Does he ever protect his mate from other birds?
Write this out, carefully drawing your conclusions from your own observations. After the young birds have left the nest and have no further use for it, you may take the nest and examine it closely. You will find that while there is a similarity in the nests of the same kind of birds, they differ considerably in the materials of which they are composed. For example, the typical robin's nest consists of straws and hairs plastered together with mud and lined with some soft material, but others have been found made entirely of raveled rope; others of carpet rags. The bird evidently is not guided in this matter by blind instinct, but uses its reason in adapting materials that are at hand.
If you are fortunate you may find a pair of orioles building their nest. Place some bright-colored yarn or string in pieces of convenient length where the birds will see them. Some of them are almost sure to be woven into the nest. The oriole's nest may be attached to a limb by two or more cords; if it is, notice how it is prevented from swinging by side ropes. You will find it guyed against the prevailing winds. The oriole frequently ties several twigs together, and so uses these to suspend his nest. Notice the nest pouch; those built near houses are quite shallow; those near forests are much deeper. Can you tell why?
The wings of birds.—Describe the different kinds, as short and round, or long and slender, and the effect of the wing-shape upon the bird's motion in the air. Describe the flights of different birds.
Songs of birds.—Write the syllables which seem to you to express the different songs of birds. Notice the different songs of the same bird. A song sparrow was observed to have twelve different songs. He sang each one several times over, as if each song had a number of verses. Then changing his position, he would sing another. To most ears the robin's song is always the same, but close attention discovers that there are variations. Many birds are genuine musicians and compose as they sing, not having formal songs.
Free description of birds.—Write description of some bird of your acquaintance, noting the following:—
Its appearance.—Color, gait, flight, size from tip of beak to end of tail, spread of wings.
Its common name.—Why given?
Time of arrival and departure.
Character.—Is it trustful, or shy and retiring?
Song.—Season when song is most frequent, also times of day. Does it consist of many or only a few notes? Is it cheery, like the robin's, or tuneful, like the thrush's, or rollicking and rapturous, like the bobolink's, or a Romanza, like the catbird's? Notice the different emotion sounds, the notes of fear, of parental or conjugal reprimand, of joy, of anger, of deep sorrow, made by the bird at times.
Food.—Insects (kinds), seeds, fruit, etc.
Nest.—Where placed, how made?
Incidents.—From the writer's knowledge of the bird.
This bird in literature.—What writers have described, what poets have immortalized him? How did they characterize him?
Some of the following books are almost indispensable to one who wishes to know the birds:—
"Wake Robin," John Burroughs; "Birds and Poets," John Burroughs; "The Birds and Seasons of New England," Wilson Flagg; "Upland and Meadow," Charles C. Abbott; "Bird Ways," Olive Thorne Miller; "Birds through an Opera Glass," Florence A. Merriam; "Birds in the Bush," Bradford Torrey; "The Birds About Us," Charles C. Abbott; "From Blomidon to Smoky," Frank Bolles.
Recent magazines should be searched and the current ones scrutinized for articles by any of the above-named writers.
Destruction of birds.—Find out how many birds are annually slaughtered in the United States, and for what purposes.
In the report of the American Ornithologist Union published in 1886, it was estimated that about five million birds were annually required to fill the demand for the ornamentation of the hats of the American women. In 1896 it was estimated that the number thus used was ten million. "The slaughter is not confined to song-birds; everything that wears feathers is a target for the bird butcher. The destruction of 40,000 terns in a single season on Cape Cod, a million rail and reed birds (bobolinks) killed in a single month near Philadelphia, are facts that may well furnish food for reflection. The swamps and marshes of Florida are well known to have become depopulated of their egrets and herons, while the state at large has been for years a favorite slaughter ground of the milliners' emissaries." An article in Forest and Stream, speaking of the destruction of birds on Long Island, states that during a short period of four months 20,000 were supplied to the New York dealers from a single village.
The Audubon Society of Massachusetts has looked up the figures and reports that "it is proved that into England alone between 25,000,000 and 30,000,000 birds are imported yearly, and that for Europe the number reaches 150,000,000. Hence, the fashionable craze has annually demanded between 200,000,000 and 300,000,000 birds. From the East Indies alone a dealer in London received 400,000 humming birds, 6,000 birds of paradise, and 400,000 miscellaneous birds. In an auction room, also in London, within four months, over 800,000 East and West Indian and Brazilian bird skins, besides thousands of pheasants and birds of paradise, were put up for sale."
This demand for birds has been going on for a quarter of a century, and billions of rich-plumaged creatures have been slaughtered to meet it, and several of the feathered tribes have been exterminated.
Write to the following for literature upon the destruction of birds:—
Humane Education Committee, 61 Westminster Street, Providence, R. I.; George T. Angell, Boston, Mass.; Secretary of the Massachusetts Audubon Society, Boston, Mass.; Secretary of the New York Audubon Society at New York; Secretary of the Department of Agriculture, Washington, D. C.; Secretary of the Audubon Society of Pennsylvania at Philadelphia; also write to the Department of Agriculture of your own state.
