HIS TRAVELS

Most of our birds take two long journeys every year, one in the fall to the south, and the other in the spring back to the north. These journeys are called "migrations."

The birds do not go all at once, but in many cases those of a kind who live near each other collect in a flock and travel together. Each species or kind has its own time to go.

It might be thought that it is because of the cold that so many birds move to a warmer climate. But it is not so; they are very well dressed to endure cold. Their feather suits are so warm that some of our smallest and weakest birds are able to stay with us, like the chickadee and the golden-crowned kinglet. It is simply because they cannot get food in winter, that they have to go.

The fall travel begins soon after the first of July. The bobolink is one of the first to leave us, though he does not start at once on his long journey. By that time his little folk are full grown, and can take care of themselves, and he is getting on his winter suit, or moulting.

Then some morning all the bobolinks in the country are turned out of their homes in the meadows, by men and horses and mowing-machines, for at that time the long grass is ready to cut.

Then he begins to think about the wild rice which is getting just right to eat. Besides, he likes to take his long journey to South America in an easy way, stopping here and there as he goes. So some morning we miss his cheerful call, and if we go to the meadow we shall not be able to see a single bobolink.

There, too, are the swallows, who eat only small flying insects. As the weather grows cooler, these tiny flies are no longer to be found. So the swallows begin to flock, as it is called. For a few days they will be seen on fences and telegraph wires, chattering and making a great noise, and then some morning they will all be gone.

They spend some time in marshes, and other lonely places, before they at last set out for the south.

As the days grow shorter and cooler, the warblers go. These are the bright-colored little fellows, who live mostly in the tops of trees. Then the orioles and the thrushes and the cuckoos leave us, and most birds who live on insects.

By the time that November comes in, few of them will be left. Birds who can live on seeds and winter berries, such as cedar-berries and partridge-berries, and others, often stay with us,—bluebirds, finches, and sometimes robins.

Many birds take their journey by night. Think of it! Tiny creatures, that all summer go to bed at dark, start off some night, when it seems as if they ought to be asleep, and fly all night in the dark.

When it grows light, they stop in some place where they can feed and rest. And the next night, or two or three nights later, they go on again. So they do till they reach their winter home, hundreds or thousands of miles away.

These night flyers are the timid birds, and those who live in the woods, and do not like to be seen,—thrushes, wrens, vireos, and others. Birds with strong wings, who are used to flying hours every day, and bolder birds, who do not mind being seen, take their journey by daylight.

Most of them stop now and then, a day or two at a time, to feed and rest. They fly very high, and faster than our railroad trains can go.

In the spring the birds take their second long journey, back to their last year's home.

How they know their way on these journeys, men have been for many years trying to find out. They have found that birds travel on regular roads, or routes, that follow the rivers and the shore of the ocean. They can see much better than we can, and even in the night they can see water.

One such road, or highway, is over the harbor of New York. When the statue of Liberty was set up on an island in the harbor a few years ago, it was put in the birds' path.

Usually they fly too high to mind it; but when there is a rain or fog they come much lower, and, sad to say, many of them fly against it and are killed.

We often see strange birds in our city streets and parks, while they are passing through on their migrations, for they sometimes spend several days with us.

A sparrow, who was hurt and unable to fly, was picked up one fall and kept in a house all winter. He was not caged, and he chose for his headquarters and sleeping-place a vase that stood on a shelf.

He went with the family to the table, and made himself very much at home there. He picked out what he wanted to eat and drink, and scolded well if he did not have it.

The thing he liked best was butter, and when he was ready to wipe his bill after eating, as birds do, he found the coat-sleeve of the master soft and nice for the purpose. This pleased the bird better than it did the owner of the sleeve, but he tried in vain to keep the saucy fellow off. If he forgot for an instant to watch the bird, he would dash up, wipe off the butter, and fly away out of the reach of everybody.

In the spring the sparrow left the family, and lived out of doors. But, with the first cold weather of fall, he came back, went to his old vase, and settled himself for the winter again. This he did for several years.
