So every time the crows came over, Tommy would stretch up in his seat and finally slip out of it entirely and, hanging half out of the window, shake his fist at them, all the time uttering dire threats of what he would do if he only had his father’s shot-gun.

For these reasons, Friday morning saw him seated in the middle of the room with the older girls and sharing the double desk with Sarah Barnes. Now Sarah thought that Tommy was the cleverest boy she had ever seen, and Sarah had visited in Centre Village in Hattertown, and Bridgeton, been twice to the Oldtown County Fair, and would have gone to New York once with her Aunt Jane if measles had not prevented; so that her friends thought, for thirteen, she was quite a travelled lady.

Tommy also considered her favourably and had been heard to say that she was not bad for a girl; yet, to be put in the middle seats with the girls he considered an insult to his years, and he was sulky and brooded mischief all the morning.

In reality Tommy was not a bad boy in any way. What he wanted was plenty of occupation for his mind and body to work at. Miss Wilde knew this and tried to give him as many little things to do as possible. It was Tommy who had charge of the new cage rat-trap of shiny copper wire, in which it was hoped the field rats might be caught, that, as soon as cool weather came, gnawed their way in through the loose floor boards and sometimes destroyed the books, and, as Sarah Barnes declared (whose duty it was to keep the wells filled), drank the ink. Tommy also kept the water-pail full and tended the big wood-stove in winter; but none of these tasks seemed to touch the restless spot and he could think out more puzzling questions in a day than the whole school board could have answered in a week, and then, as Sarah Barnes once said, “Tommy Todd’s questions never seem to stay answered.”

Miss Wilde had taught, at first, in the school of a large town where there were plenty of pictures and maps on the walls, and charts of different kinds and reference books for the children to use, and where people who loved children would often drop in and tell them about birds and flowers or their journeys to interesting places. She had taken the country school because the doctor thought it would be better for her health, and oh, how she wished that she could have brought some of the pictures and books with her, or that some of the summer boarders who stayed until almost winter would come in and talk to her pupils. She told the children stories or read to them on Friday afternoons. She also knew that there were some travelling libraries of books that she might borrow that the children could have themselves, but reading is a habit; the children needed to be interested first. So it came about that, when the second year of her school life on the hillside began, Miss Wilde felt rather discouraged.

On this particular rainy Friday she was feeling worried about her mother, who boarded at the Centre Village and with whom she spent every week-end, going down with the mail-carrier on his return trip Friday evening and usually walking back on Sunday afternoon if no one chanced to be driving that way. Mrs. Wilde had been ill the Sunday before and Miss Wilde had not heard a word all the week. Everything had gone awry that morning, and when the last child had filed out for the dinner-hour and gone splish-splashing up the muddy road, before straightening out the room as usual, Miss Wilde sat down at the desk, her head in her hands, and two big tears splashed down on the inky blotting-paper before her. Presently she wiped her eyes, opened all the windows that the rain did not enter, took her box of luncheon from her desk, and walked slowly down the side aisle to the little porch, which also acted as the cloak-room, the place where she usually ate her luncheon when it was too cool or wet to go outdoors.

As she passed Tommy Todd’s desk she thought she heard a noise, and glanced sideways, half expecting to see him crouching under it, bent upon some prank. No one was there, and still there was a scratching sound in that vicinity. Opening the desk lid, Miss Wilde gave a scream, for inside was the new trap and inside the trap two wicked-looking old rats whose whiskers had evidently grown gray with experience.

“I wonder what he would have done with them if I had not found him out?” she said to herself, as she lifted the cage, by hooking the crook of her umbrella into the handle on the top, and carrying it with the greatest care, put it into the empty wood-box in the porch. Then she seated herself on the bench by the outer door and unstrapped her box. But it evidently was not intended that the poor teacher should lunch that day, for suddenly the door flew open and the weather-beaten face of Joel Hanks, the carrier who had the forenoon mail-route, peered anxiously in.

“You here, Miss Wilde?” he called anxiously. “I’m glad yer hain’t gone up to the house for your nooning, cause I clean fergot when I come by up, but yer Ma’s feelin’ extra poorly and uneasy, and she thought mebbe you could come back along with me instead of waiting till night. I’m goin’ to eat over to Todd’s and I can stop back for you close to one if you can arrange to go.”

“Oh, I wish I had known it before the children went to dinner,” she cried, clasping her hands together nervously and dropping the box, out of which her lunch rolled to the floor, amid the damp that had been made by wet coats, overshoes, and dripping umbrellas. “As it is, when the children come back, I cannot send them right home again, for some have a long walk. If it wasn’t for Tommy Todd, I could leave Sarah Barnes for monitor; but there are those rats, and the school board does not like me to shorten hours so soon after vacation. It’s too late for me to go over for Mrs. Bradford, or I know that she would help me by coming as she did several times last spring.”

“Sorry I couldn’t stop this morning, but I come by the lower road. Wall, mebbe you’ll think out some way and I’ll stop back a bit a’ter one,” Joel said cheerfully, going back to his covered cart and chirping to his wise old horse, who, though he was gaunt and had only one good eye, knew every letter-box on the route and solemnly zig-zagged across the road from one to the other on his way up to Foxes Corners, but as surely passed them by without notice on the return trip.

Miss Wilde had barely swept away the scattered lunch through the open door when again she heard wheels, and looking up saw that which made her stand stock-still in surprise, broom in hand,—a trim, glass-windowed depot wagon, such as she had seldom seen out of Bridgeton, drawn by a handsome pair of gray horses, whose long, flowing tails were neatly braided and fastened up from the mud with leather bands, instead of being cruelly docked short as sometimes happens. The driver, a pleasant-looking, rosy-cheeked man, was well protected by coat and boot of rubber; but before Miss Wilde could more than glance at the outfit the door opened and a lady stepped lightly out, reaching the school porch so quickly that she had no need of an umbrella.

Spying Miss Wilde, she said in a voice clear as a bell, and yet so well modulated and sweet that no one who heard her speak ever forgot its sound—“Are you the teacher here?”

“Yes.”

“And your name?”

“Rosamond Wilde,” replied the astonished girl, hastily hanging up the broom, unconsciously leading the way into the stuffy schoolroom and placing the best chair by the side of her desk, as she did when the minister, Dr. Gibbs, from Centre Village, who was president of the school board, came to hold a spelling-match.

“Thank you,” said the silvery voice, as its owner took the proffered seat, turning so that she could look out of the window.

“I have heard from Dr. Gibbs that you sometimes use part of Friday afternoon for telling the children stories, or reading something that may amuse as well as teach them, and I thought that perhaps, as the board does not object, you might sometimes be willing to have me come in and talk to them. I am very fond of children, and have one little girl of my own, so that I know very well what they enjoy. I’ve travelled for several years, and I have a great many interesting pictures I could show them. Then, too, I have always loved birds and flowers, and with my father I used to tramp about and learned to know all those of this neighbourhood. I well remember that when I was a child and studied at home, rainy Friday afternoons were always pleasant, because mother, my cousins, and I had fancy-work or some other sewing and stories; so I thought to-day perhaps would be a good time for a beginning.”

If the sky had opened and an angel come directly to her aid, Miss Wilde could not have been more overcome. She pulled herself together and began to frame a polite answer, when looking at the guest, who had thrown off her light raincoat, she caught the sympathetic glance that shot from a lovely pair of gray eyes with black lashes, and saw that the fluffy gray hair belonged to a really young woman, but a little older than herself. Forgetting that a teacher is supposed never to lose control of herself, before she realized that she had said a word she had told this friend in need about her school, Tommy Todd, her mother’s sickness, and all.

In less time than it takes to tell of it, the coachman had been told to go down to the blacksmith’s shop and wait under cover until three o’clock, and Miss Wilde was helped to make her preparation for leaving.

When the children came trooping back, they found the door between cloak-room and schoolroom closed, and teacher waiting for them in the outer room with very rosy cheeks and a happier expression than her face usually wore.

Tommy Todd looked relieved, for, he reasoned, if teacher knew there were two rats in his desk, she would not have looked pleased. In a few words Miss Wilde explained the happenings, cautioned them to be very good, and saying, “Right, left, right, left,” was about to open the door for the children to march in, when Sarah Barnes asked, “Teacher, what is her name, so we can call her by it?” Then teacher realized that she didn’t know. But as the door opened Sarah said, in a very loud whisper, as whispers are apt to sound louder than the natural voice, “Why, it’s my Gray Lady!” and so in truth it was.

Teacher watched them until they took their seats, and then gently closed the door behind her. For a moment no one spoke. Tommy Todd peeped cautiously into his desk to be sure the rats were safe, and found to his dismay that they were gone. Inwardly he hoped they wouldn’t get loose, for Gray Lady didn’t look as if she would like rats, which showed that after only one glance he wished to please her, while at the same time the name by which they first knew her became fixed in the mind of every child.

The silence inside the school continued a full minute, that seemed like an hour, and the dripping of the rain from the gutter was so plain that Sarah found herself counting the drops—“One—two—three—four—splash!”

Fifteen pairs of eyes were fastened upon the newcomer, and, as she caught the various questions in them, the colour in her cheeks deepened. Suddenly she recognized her little friend whom she had met on the hillside the week before. “Sarah Barnes,” said Gray Lady, “will you not tell me the names of your schoolmates and introduce me to them? It is always so much more pleasant when we are looking at people, places, or things to know what they are called.”

Then Sarah, delighted at being remembered when she had begun to be quite sure that all her hopes were in vain, guided by an inborn instinct of politeness that told her it would not be civil to stand at her desk and call out the various names, marched solemnly up to the teacher’s desk and, beginning in the front row with her own little sister Mary, repeated the fifteen names in full, with the greatest care and distinctness, and each child, not knowing what else to do, bobbed up and answered, “Present,” the same as if teacher had been calling the roll. When Sarah had finished, she was quite out of breath, for some of the names were very long; the last, that of the one little Slav in the school, Zella Francesca Mowralski, being also hard to pronounce.

“Thank you,” said Gray Lady; “I think that I can remember the first names at least. But now that you have presented your friends to me, won’t you kindly present me to them? You know who I am and where I live, do you not?”

“Of course I do!” cried Sarah, glad to be in smooth water again. “You are Goldilocks’ mother, Gray Lady, and you are our General’s daughter and you live in his house!” Then, realizing that she had given play to her own fancy rather than stated the facts expected, she fled to her desk and hid her face behind its lid.

No reproof followed her as she expected, but instead the pleasant voice again said: “Thank you, Sarah; I like the name you have given me better than my very own, and if you all know where to find the General’s house, you know where to find me,” and when Sarah, gaining courage, looked up again, she saw, what the others did not notice, that the gray eyes were brimming, though there was a smile on her lips.

“Now, children, what would you like to hear about this afternoon? Miss Wilde told me that she had intended giving you a spelling review and writing exercise of some kind, but that we might finish the day as we choose. Shall I read you a story, or would you like to ask questions and talk best?—one at a time, of course!”

“Talk—you talk,” shouted a vigorous chorus.

“By the way, Tommy Todd,” said Gray Lady, “why do you sit in the middle with the girls instead of on the outer row with the boys, where there is more room?”

Tommy, placed between Sarah Barnes and his own sister, started half up in his seat and looked all round the room as if seeking a way of escape, and finding none, dropped his gaze to his desk and sat mute with a very red face.

The question was repeated—still no answer. A hand flew up. “I know,” piped the voice of one of the little ones in front; “it’s ’cause Tommy can’t keep his eyes inside the winder if he’s by it; he’s always spying out at ground-hogs and crows and askin’ teacher questions about the birds setting on the wires, so he don’t mind his books and teacher don’t know the answers to all he asks, an’ it gives her the headache!”

“Well, Tommy,” said Gray Lady, who had learned that at least one of the children before her cared for out-of-doors, which was precisely what she wanted to know, “as long as this is a sort of holiday, suppose you take that empty seat by the east window and tell us what you see. You may open the window and the others on that side also, for I think the rain is over; yes, the clouds are breaking away.”

How fresh and sweet the air was that rushed into the close room! Tommy stuck his head out and took a great breath as he looked down over the corn-fields,—his enemies the crows were not there.

“There isn’t much to see now, it’s too wet yet,” he said; “but pretty soon there will be, for most birds and things get hungry right after a rain!”

“Olit—olit—olit—che-wiss-ch-wiss-war,” sang a little bird in a low bush by the roadside.

“What bird is that,” asked Gray Lady; “do any of you know?”

“It’s just the usually little brown bird that stays around here most all the time, but I love the tune it sings,” said Sarah Barnes. “Teacher says it’s some kind of a sparrow.”

Then questions flew so thick and fast that Gray Lady could not even hear herself think, and presently, when every one had laughed at the confusion, order was restored.

“I asked you a moment ago what you would like to hear about. I think I know. You would like to hear about birds! Are there any other boys here besides Tommy and Dave who care about birds?” asked Gray Lady, who wished to have each child feel that he or she had a part in what was going on.

“I know about birds’ eggs!” cried Bobby Bates, a boy who, from being undersized, looked much younger than he really was; “I’ve got a pint fruit-jar of robins’ eggs.”

“But I’ve got a quart jar of mixed eggs,” said Dave, “and they’re mostly little ones, Wrens and Chippy birds and such like, so’s I’ve really got more’n Bobby!” he added boastfully.

Gray Lady opened her lips to speak sharply and her eyes flashed, for nest-robbing was one of the things she most detested. Then she remembered that perhaps these children had not only never even dreamed that there was any harm in it, but had never heard of the laws that wise people had made to protect the eggs of wild birds, as well as the birds themselves, from harm. So she hesitated a moment while she thought how she might best make the matter understood.

“Why do you like to collect eggs?” she asked. “Because they are pretty?”

“Yes’m, partly,” drawled Dave, “and then to see how many I can get in a spring.”

“But do you never think how you worry the mother birds by stealing their eggs, and how many more birds there would be if you let the eggs hatch out? What the rhyme says is true,—

Only think, if all those robins’ eggs of yours, Bobby, and all your little eggs, Dave, should suddenly turn into birds and fly about the room, how many there would be! But now they will never have wings and swell their throats to sing to us and use their beaks to eat up insects that make the apples wormy and curl up the leaves of the great shade trees.”

“I know that Robins sometimes eat fruit,” said Gray Lady, firmly, “but they do so much more good by destroying bugs that the Wise Men say that neither they nor their eggs shall be taken or destroyed, and what they say is now a law. So that it is not for any one to do as he pleases in the matter. To kill song-birds or destroy their eggs is as much breaking the law as if you stole a man’s horse or cow, for these birds are not yours; they belong to the state in which you live.”

Bobby and Dave looked surprised, but Tommy and Sarah nodded to one another, as much as to say, “We knew that, didn’t we?”

“Some day, if you are clever with your lessons so that Miss Wilde can spare the time for it, I will tell you all about the reasons for these laws, and what the wild birds do for us, and what we should do for them. But first you must learn to know the names of some of the birds that live and visit hereabout, as I am now learning yours, and make friends of some of them as I hope to make friends of you.”

“Yes, yes, oh, yes!”

“You can’t make friends of birds; they won’t let you,” said Dave Drake, who was a sickly, lanky boy of fourteen with a whining voice; “they always fly away. That is, I mean tree birds, not chickens nor pigeons.”

“Chickens aren’t birds, they’re only young hens,” put in Eliza Clausen, with an expression of withering contempt. She was one of the big fourteen-year-old girls, and not being a good scholar was apt to use opposition in the place of information.

“We can make friends of at least some birds,” said Gray Lady, “if we are kind to them. When we have human visitors come to stay with us, what do we do for them?”

“We let them sleep in the best bedroom, and we get out the best china and have awful good things to eat, and give ’em a good time,” said Ruth Barnes, all in one breath.

“Yes, and we should do much the same with our bird friends. They do not need to have a bedroom prepared; they can generally find that for themselves, though even this is sometimes necessary in bad weather; but they often need food, and in order that they should have what Ruth calls ‘a good time,’ we must let them alone and not interfere with their comings and goings.

“Go softly to the west window and look out,” continued Gray Lady, raising a finger to caution silence, for from her seat on the little platform she could see over the children’s heads and out both door and windows, “and see the hungry visitors that a little food has brought to the very door.”

“As we have agreed to talk and ask questions, I will ask the first one,” said Gray Lady, as they all settled down, feeling very good-natured and eager to listen.

“Eliza said a few minutes ago that a chicken isn’t a bird. Now a chicken is a bird, though of course all birds are not chickens.

The Bird

“Who can tell me exactly what a bird is? You all may think you know, but can you put it in words?”

“A bird isn’t a plant; it is an animal,” said Tommy Todd.

“Yes, but a cat is an animal, and a snake, and a horse; and we are animals ourselves.”

“A bird is a flying animal,” returned Sarah.

“Very true, but so is a bat, and, as you know, a bat has fur and looks very like a mouse, and a bird does not.

“Ah, you give it up. Very well, listen and remember. A bird is the only animal which has feathers! With his hollow bones filled with buoyant, warm air, and covered with these strong pinions, he rows through the air, as we row a boat through the water with the oars, balancing himself with these wings, also steering himself with them and with his tail made of stiff feathers and shaped to his particular need, while with small feathers laid close, overlapping each other like shingles, and bedded on an under-coat of down, he is clothed and protected from heat, cold, and wet.

“The eye of the bird is different from ours, for it magnifies and makes objects appear much larger to it than they do to us. Also, while with other animals each group has practically the same kind of feet or beaks, birds have these two features built on widely different plans, so that when you have learned to know the common birds by name and are really studying bird-life, you will find that you must be guided to the orders in which they belong often by their beaks and feet.

“Barnyard Ducks, as you know, have webbed toes for swimming, and flat bills to aid them in shovelling their natural food from the mud.

“Birds of prey, like the Hawks and Owls, have strong hooked beaks and powerful talons or claws, for seizing and tearing the small animals upon which they feed.

“The Woodpeckers (all but one) have two front and two hind toes; these help them grasp the tree bark firmly as they rest, while they have strong-cutting, chisel-like beaks, which they also use for tapping or drumming their rolling love-songs.

“While the insect-eating song-birds have more or less slender bills and four toes, three in front and one behind, for perching crosswise on small branches, the seed-eating songsters, such as Sparrows, have similar feet, but short, stout, cone-shaped bills for cracking seeds and small nuts.

“By this you can see that in spite of the fact that all birds wear feathers, and have wings, a tail, beak, and a pair of legs, they may still be very different from each other.

“A Turkey Gobbler doesn’t look much like a Robin, nor a Goose like a Swallow, yet they are all four birds! They all four bring forth their young from eggs; but the little Turkeys and Goslings are covered with feathers when they peep out of the shell and are able to walk, while the young Robins and Swallows are at first blind, naked, and helpless; so here again you can see that there is something special to be learned about every bird that flies or swims.”

“The little bird peeping in the window and calling his name reminds me of a pretty poem about him,” said Gray Lady. “I will repeat it to you and write it on the board so that you can copy it in your books, and then some of you may like to learn it to surprise Miss Wilde on another rainy Friday.”

A LITTLE MINISTER

“Now that I have answered my own question, there was another that one of you asked, or rather a pair of questions. Why do some birds go away in autumn, and why do they come back? It is very important to know the answers to these, if we want to really understand about the lives of birds and the trials and dangers they undergo.

The Bird Year and the Migration

“People who think of birds at all know that they are not equally plentiful at all times of the year, but that they have their seasons of coming and disappearing, as the flowers have, though not for exactly the same reason.

“We are accustomed to see the plants send up shoots through the bare ground every spring, unfold their leaves and blossoms, and, finally, after perfecting seed, wither away again at the touch of frost.

“Of these plants, as well as some large trees, a few are more hardy than others, like the ground-pine, laurel, and wintergreen, and are able to hold their leaves through very cold weather, and we call them evergreens.

“You notice that the birds appear in spring even before the pussy-willows bud out, and that every morning when you wake, the music outside the window and down among the alders on the meadow border is growing louder, until by the time the apple trees are in bloom there seems to be a bird for every tree, bush, and tuft of sedgegrass.

“By the time the timothy is cut and rye harvested, you do not hear so great a variety of song. The Robin, Song Sparrow, House Wren, and Meadowlark are still in good voice, and an occasional Catbird, but the Bobolink has dropped out, and the Brown Thrasher no longer tells the farmer how to plant his corn: ‘Drop it, drop it, cover it up, hoe it, hoe it;’ and very wise he is, too, for the corn is all planted.

“Later still, when the stacked cornstalks fill the fields with their wigwams, like Indian encampments, the pumpkins are gathered in golden heaps, and the smoke of burning leaves and brush pervades the air, you hear very few bird songs, for many birds have either dropped silently out of sight or collected in huge flocks, like the Swallow, swept by, and disappeared in the clouds, while others, like the Purple Grackle or Common Crow-Blackbird,—walk over the stubble and cover the trees, making such a creaking, crackling noise that one would surely think that their wings as well as voices were rusty and needed oiling.

“What has become of the birds? Where do they go when they disappear?

“Being warm-blooded animals they cannot dive into the mud and hide, like fishes, or crawl into cracks of tree bark and wrap themselves up in cocoons, like insects. Neither do they drop their feathers and die away as tender plants drop their leaves and disappear.

“People once believed that Swallows dived through the water into the mud, where they rolled themselves into balls and slept all winter. They thought this because Swallows are seen in early autumn in flocks about ponds and marshes, where they feed upon the insects that abound in such places. People thought that as Swallows were last seen in these places before they disappeared they must have gone under the water; but this was merely guessing, which is a very dangerous thing to do when trying to find out the plans that Nature makes for her great family.

“Later yet, when the snow begins to fall, there is little or no bird music, only the hoot of an Owl, the shrill cry of the Hawks, the ‘quank, quank’ of the Nuthatch, that runs up and down the tree-trunks like a mouse in gray-and-white feathers, the jeer of the Jay, and the soft voice of the Chickadee that, as you have just heard, tells you his name so prettily as he peers at you from beneath his little black cap.

“But the Catbird, Wren, Bobolink, Oriole, the Cuckoo that helped clear the tent caterpillars from the orchard, the Chat that puzzled the dogs by whistling like their master, the beautiful Barn Swallow, with the swift wings, that had his plaster nest in the hayloft, the Phœbe that built in the cowshed, and the dainty Humming-bird that haunted the honeysuckle on the porch and hummed an ancient spinning-song to us with his wings,—where are they all?

“And why is it that while those have disappeared, some few birds still remain with us in spite of cold and snow?”

THE FLIGHT OF THE BIRDS

The Fall Migration

“If you watch the birds, you will soon notice that some eat only animal food, in the shape of various bugs, worms, and lice, while others eat seeds of various weeds, and grasses, and also berries. There are many birds that, like ourselves, eat a little of everything, both animal and vegetable.

“You know that when frost comes, the air-flying insects are killed, and the gnats, mosquitoes, and flies that have worried the horses and cattle disappear. For this reason the birds that depend upon these bugs must follow their food supply, and move off farther southward where frost has not yet come.

“This is the reason why so many birds who feed on winged insects leave us in early autumn, before it is cold enough to make them uncomfortable; they must follow their food.

“There are other birds that, when they no longer have nestlings to feed, can pick up a living from berries and seeds, like the Robin, or live the greater part of the season upon seeds, like the Sparrows. These birds are not driven away by the first frost, but many stay about until the weather is uncomfortably cold, and some few remain all winter, like the Meadowlarks, Nuthatches, Jays, and Woodpeckers, who, having stout beaks, can dig out grubs and insects from among the roots of grass and from tough tree bark; but these too must move on if ice coats the trees or snow buries their ground feeding-places.

“As a great many birds spend the nesting season north of New England, they pass by on their way southward, and, if the feeding is good, stay with us sometimes several weeks, so that the flocks of Robins seen here in October are likely to be those that nested in the north, while our own birds are gradually drifting down to the extreme south, where they winter.

“This great southward journey of the birds, that begins as early as August and lasts at some seasons, if the winter is open, almost until Christmas, is called the fall migration, and when it is over, the birds remaining with us are classed as Winter Residents.

“There is another thing to be seen at this time of year, and if you have not already noticed it, watch and you will see that many of the birds that wore bright feathers in May and June have changed their gay coats for duller feathers.

The Moulting

“After the nesting season is over, and a pair of birds have raised one, two, and, as with the Wrens, sometimes three broods, the feathers of the parents become worn and broken, and not fit for winter covering, nor are the wing quills strong enough for the fall flight.

“At this time, when the young birds are able to care for themselves, the pairs no longer keep alone together, but, leaving their nesting-haunts, travel about either in a family party or in larger friendly flocks, and, although some birds, like the Song Sparrow and Meadowlark, sing throughout the season, the general morning chorus and the nesting season end together, in early or middle July.

“It is quite difficult to name the birds when young and old travel in flocks, for when a male is bright-coloured and the female dull, the first coat of the young is often such a mixture of both that it is easily mistaken for a wholly different and strange bird.

“In August or September almost all of our birds change their spring feathers. This is called moulting. And the brightly coloured birds often drop their wedding finery for dull-coloured travelling cloaks, so that they may not be seen when they fly southward through the falling leaves.
