What do birds do in the world? is an important question for us to think

about. First, we must gain by observation and by personal acquaintance

with the living birds a knowledge of their work and their way of doing

it. In getting this knowledge, let us also consider what we can do for

our birds to render their work as complete and effective as possible.

Think of what the birds are doing on every farm, in every garden,

about every home in the land. Think of the millions of beautiful wings,

of the graceful and attractive figures, of the cunning nests, and of the

singing throats! Do you think that the whole service of the birds is to

be beautiful, to sing charmingly, and to rear their little ones? By no

means is this their chief service to man. Aside from these services the

greatest work of birds is to destroy insects. It is one of the wise

provisions of nature that many of the most brilliantly winged and most

enchanting songsters are our most practical friends.

Not all birds feed on insects and animals; but even those that eat but a

small amount of insect food may still destroy insects that would have

damaged fruit and crops much more than the birds themselves do.

As to their food, birds are divided into three general classes. First,

those that live wholly or almost wholly on insects. These are called

insectivorous birds. Chief among these are the warblers, cuckoos,

swallows, martins, flycatchers, nighthawks, whippoorwills, swifts, and

humming-birds. We cannot have too many of these birds. They should be

encouraged and protected. They should be supplied with shelter and


Birds of the second class feed by preference on fruits, nuts, and grain.

The bluebird, robin, wood thrush, mocking-bird, catbird, chickadee,

cedar-bird, meadow lark, oriole, jay, crow, and woodpecker belong to

this group. These birds never fail to perform a service for us by

devouring many weed seeds.

The third class is known as the hard-billed birds. It includes those

birds which live principally on seeds and grain--the canary, goldfinch,

sparrow, and some others.

Birds that come early, like the bluebird, robin, and redwing, are of

special service in destroying insects before the insects lay their eggs

for the season.

The robins on the lawn search out the caterpillars and cutworms. The

chipping sparrow and the wren in the shrubbery look out for all kinds of

insects. They watch over the orchard and feed freely on the enemies of

the apple and other fruit trees. The trunks of these trees are often

attacked by borers, which gnaw holes in the bark and wood, and often

cause the death of the trees. The woodpeckers hunt for these appetizing

borers and by means of their barbed tongues bring them from their

hiding-places. On the outside of the bark of the trunk and branches the

bark lice work. These are devoured by the nuthatches, creepers, and


During the winter the bark is the hiding-place for hibernating insects,

which, like plant lice, feed in summer on the leaves. Throughout the

winter a single chickadee will destroy great numbers of the eggs of the

cankerworm moth and of the plant louse. The blackbirds, meadow larks,

crows, quail, and sparrows are the great protectors of the meadow and

field crops. These birds feed on the army worms and cutworms that do so

much injury to the young shoots; they also destroy the chinch bug and

the grasshopper, both of which feed on cultivated plants.

A count of all the different kinds of animals shows that insects make up

nine tenths of them. Hence it is easy to see that if something did not

check their increase they would soon almost overrun the earth. Our

forests and orchards furnish homes and breeding-places for most of these

insects. Suppose the injurious insects were allowed to multiply

unchecked in the forests, their numbers would so increase that they

would invade our fields and create as much terror among the farmers as

they did in Pharaoh's Egypt. The birds are the only direct friends man

has to destroy these harmful insects. What benefactors, then, these

little feathered neighbors are!

It has been estimated that a bird will devour thirty insects daily. Even

in a widely extended forest region a very few birds to the acre, if they

kept up this rate, would daily destroy many bushels of insects that

would play havoc with the neighboring orchards and fields.

Do not imagine, however, that to destroy insects is the only use of

birds. The day is far more delightful when the birds sing, and when we

see them flit in and out, giving us a glimpse now and then of their

pretty coats and quaint ways. By giving them a home we can surround

ourselves with many birds, sweet of song and brilliant of plumage.

If the birds felt that man were a friend and not a foe, they would often

turn to him for protection. During times of severe storm, extreme

drought, or scarcity of food, if the birds were sufficiently tamed to

come to man as their friend, as they do in rare cases now, a little food

and shelter might tide them over the hard time and their service

afterwards would repay the outlay a thousandfold. If the boys in your

families would build bird-houses about the house and barn and in shade

trees, they might save yearly a great number of birds. In building these

places of shelter and comfort, due care must be taken to keep them

clear of English sparrows and out of the reach of cats and bird-dogs.

Whatever we do to attract the birds to make homes on the premises must

be done at the right time and in the right way. Think out carefully what

materials to provide for them. Bits of string, linen, cotton, yarn, tow

and other waste material, all help to induce a pair to build in the


It is an interesting study--the preparation of homes for the birds.

Trees may be pruned to make inviting crotches. A tangled, overgrown

corner in the garden will invite some birds to nest.

Wrens, bluebirds, chickadees, martins, and some other varieties are all

glad to set up housekeeping in man-made houses. The proper size for a

bird-room is easily remembered. Give each room six square inches of

floor space and make it eight inches high. Old, weathered boards should

be used; or, if paint is employed, a dull color to resemble an old

tree-trunk will be most inviting. A single opening near the top should

be made two inches in diameter for the larger birds; but if the house is

to be headquarters for the wren, a one-inch opening is quite large

enough, and the small door serves all the better to keep out English


The barn attic should be turned over to the swallows. Small holes may be

cut high up in the gables and left open during the time that the

swallows remain with us. They will more than pay for shelter by the good

work they do in ridding the barn of flies, gnats, and mosquitoes.
