tree in a tub next to a front door, where people passed in and out continually. Doubtless very many birds would be glad of the shelter of our comfortable homes for theirs if they could only trust us. Is it not a shame that they cannot? Robins, especially, need a roof over their heads. When they foolishly saddle their nest on to an exposed limb of a tree, the first heavy rain is likely to soften the mud walls, and wash apart the heavy, bulky structure, when

"Down tumble babies and cradle and all."

{7}

It is wiser of them to fit the nest into the supporting crotch of a tree, as many do, and wisest to choose the top of a piazza pillar, where boys and girls and cats cannot climb to molest them, nor storms dissolve their mud-walled nursery. There are far too many tragedies of the nests after every heavy spring rain.

Suppose your appetite were so large that you were compelled to eat more than your weight of food every day, and suppose you had three or four brothers and sisters, just your own size, and just as ravenously hungry. These are the conditions in every normal robin family, so you can easily imagine how hard the father and mother birds must work to keep their fledglings' crops filled. No wonder robins like to live near our homes where the enriched land contains many fat grubs, and the smooth lawns, that they run across so lightly, make hunting for earth worms comparatively easy. It is estimated that about fourteen feet of worms (if placed end to end) are drawn out of the ground daily by a pair of robins with a nestful of babies to feed. When one of the parents alights near its home, every child must have seen the little heads, with wide-stretched, yellow bills, pop up suddenly like Jacks-in-the-box. How rudely the greedy babies push and jostle one another to get the most dinner, and how noisily they clamour for it! Earth worms are the staff of {8} life to them just as bread is to children, but robins destroy vast quantities of other worms and insects more injurious to the farmers' crops, so that the strawberries and cherries they take in June should not be grudged them.

A man of science, who devoted many hours of study to learn the great variety of sounds made by common barnyard chickens in expressing their entire range of feeling, from the egg shell to the axe, could entertain an audience delightfully for an evening by imitating them. Similar study applied to robins would reveal as surprisingly rich results, but probably less funny. No bird that we have has so varied a repertoire as Robin Goodfellow, and I do not believe that any boy or girl alive could recognise him by every one of his calls and songs. His softly warbled salute to the sunrise differs from his lovely even-song just as widely as the rapturous melody of his courting days differs from the more subdued, tranquil love song to his brooding mate. Indignation, suspicion, fright, interrogation, peace of mind, hate, caution to take flight—these and a host of other thoughts, are expressed through his flexible voice.

"It is only when he is a baby that you could guess our robin is really a thrush."

Toward the end of June, you may see robins flying in flocks after sun-down. Old males and young birds of the first brood scatter themselves over the country by day to pick up the best living they can, but at night they collect in large numbers at some favourite roosting place. Oftentimes the weary mother birds are now raising second broods. We like to believe that the fathers return from the roosts at sun-up to help supply those insatiable babies with worms throughout the long day.

After family cares are over for the year, robins moult, and then they hide, mope, and keep silent for awhile. But in September, in a suit of new feathers, they are feeling vigorous and cheerful again; and, gathering in friendly flocks, they roam about the woodland borders to feed on the dogwood, choke cherries, juniper berries, and other small fruits. You see they change their diet with the season. By dropping the undigested berry seeds far and wide, they plant great numbers of trees and shrubs as they travel. Birds help to make the earth beautiful. With them every day is Arbour Day.

It is a very dreary time when the last robin leaves us, and an exceptionally cold winter when a few stragglers from the south-bound flocks do not remain in some sheltered, sunny, woodland hollow.

THE BLUEBIRD

Is there any sign of spring quite so welcome as the glint of the first bluebird unless it is his {10} softly whistled song? Before the farmer begins to plough the wet earth, often while the snow is still on the ground, this hardy little minstrel is making himself very much at home in our orchards and gardens while waiting for a mate to arrive from the South.

Now is the time to have ready on top of the grape arbour, or under the eaves of the barn, or nailed up in the apple tree, or set up on poles, the little one-roomed houses that bluebirds are only too happy to occupy. More enjoyable neighbours it would be hard to find. Sparrows will fight for the boxes, it is true, but if there are plenty to let, and the sparrows are persistently driven off, the bluebirds, which are a little larger though far less bold, quickly take possession. Birds that come earliest in the season and feed on insects, before they have time to multiply, are of far greater value in the field, orchard, and garden than birds that delay their return until warm weather has brought forth countless swarms of insects far beyond the control of either bird or man. Many birds would be of even greater service than they are if they received just a little encouragement to make their homes nearer ours. They could save many more millions of dollars' worth of crops for the farmers than they do if they were properly protected while rearing their ever-hungry families. As two or even three broods {11} of bluebirds may be raised in a box each spring, and as insects are their most approved baby food, you see how much it is to our interest to set up nurseries for them near our homes.

But when people are not thoughtful enough to provide them before the first of March, the bluebirds hunt for a cavity in a fence rail, or a hole in some old tree, preferably in the orchard, shortly after their arrival, and proceed to line it with grass. From three to six pale blue eggs are laid. At first the babies are blind, helpless, and almost naked. Then they grow a suit of dark feathers with speckled, thrush-like vests similar to their cousin's, the baby robin's; and it is not until they are able to fly that the lovely deep blue shade gradually appears on their grayish upper parts. Then their throat, breast, and sides turn rusty red. While creatures are helpless, a prey for any enemy to pounce upon, Nature does not dress them conspicuously, you may be sure. Adult birds, that are able to look out for themselves, may be very gaily dressed, but their children must wear sombre clothes until they grow strong and wise.

Young bluebirds are far less wild and noisy than robins, but their very sharp little claws discourage handling. These pointed hooks on the ends of their toes help them to climb out of the tree hollow, that is their natural home, into the big world that their presence makes so cheerful.

As you might expect of creatures so heavenly in colour, the disposition of bluebirds is particularly angelic. Gentleness and amiability are expressed in their soft, musical voice. Tru-al-ly, tru-al-ly, they sweetly assert when we can scarcely believe that spring is here; and
