Before people knew very much about the ways of birds, it was thought that they did not have to be taught anything, but that they knew everything they needed to know, as soon as they were born. That is, they were said to act from instinct alone, and not at all from reason, as we do.

Another notion that people had was that birds of a kind were just alike; that they looked exactly like each other, all acted in the same way, and all sang the same song.

But since we have begun to study birds more closely, we find these things are not true. We find that birds learn things by being taught, as we do. Also, they find out how to do things themselves, and they are not all alike, as so many machines.

More than this, we see that they do not look nor act exactly like each other. For when we know one robin or one oriole well, we can tell him from any other robin or oriole. And, as I said before, no two of a kind sing precisely the same song.

A bird shows his intelligence in many ways. One is by the way he acts when he cannot do as he is used to doing. A robin I know of wished to build a nest, but could not find mud to put into it, for it was a very dry time, and there were no streams near. Now a robin's nest must have mud, and the bird seemed puzzled for a while. But at last she thought of a way to get it.

She went to a bathing-dish that the people of the house kept filled with water for the birds, jumped into it, and got her legs very wet. Then she flew to the road, and tramped around in the dust and dirt.

In a short time her legs had a good coating of mud, which she carefully picked off with her bill, and took to the nest she was building.

This she did a great many times, and the lady who told me of it watched her till she had as much mud as she needed.

A bird often shows sense by the way she repairs a nest that has been thrown out of place. Sometimes she will add a new stay, tying the nest to a stronger limb. One sparrow, whose nest broke loose, put so many stays to the branch above that they made a little roof like a tent over it.

Another way a bird shows reason is in seeing the advantage of a new place. A pair of swallows lived far out in the West, hundreds of miles from any house. They had no doubt always nested in a cave, or a hole in a tree. But one day they found a house put up. It was a mere shed, to be used as a blacksmith shop, by a party of men who were looking over the country.

At once the birds saw how nice it would be to have a roof over their heads. And although there was a big fire, and the noise of men at work, they built the nest over the anvil, and reared the family in safety.

Woodpeckers have shown that they can learn. Some of them have found an easier way to get food than to dig through the bark of trees for it.

The flicker, or golden-winged woodpecker, has learned that ants and other insects are good to eat, and now he does not think of digging into bark any more.

The red-headed woodpecker has learned to catch flies like a common flycatcher. The yellow-bellied, or sapsucker, cuts holes in the trees, and eats the insects that come to feed on the sweet sap that drips from them.

Woodpeckers have also learned to cut a hole through a board and nest inside a building, instead of drilling a deep hole in the trunk of a tree for a nest.

Birds show intelligence when they draw us away from their young ones, by acting as if they were hurt and not able to fly. I have already spoken about that.

Sometimes when a bird is caught he will lie quiet and pretend to be dead. But all the time he is looking out for a chance to fly away.

A man who watched birds very closely once saw an interesting instance of their intelligence. They were two of the birds who get their food on the seashore by turning over stones and eating the creatures hidden under them. They had found a big dead fish thrown up on the beach and half buried in sand. Under such a fish they were sure they should find food, so they went to work to turn it over. The fish was three and a half feet long, and the birds were about as big as our sandpipers. So it was a hard thing to do.

First they pushed against it with their beaks and breast, but it did not move. Then they went around the other side and scratched away a good deal of sand from under the fish, and went back and tried again to turn it over. Still it was too heavy to stir.Again they ran around the other side, scraped away more sand, and tried it once more. They kept up this work for half an hour, but did not succeed in stirring the great fish.

At this time the man, who had hidden himself to watch them, saw another bird coming. The two little workers greeted him with joyful cries, to which he replied in the same tones. Then all three set to work on the heavy fish. They dug more sand out from the lower side, and then pushed against the upper side with all their strength. They lifted it a few inches, but it fell back.

At last, after resting a few minutes, without moving from their places, they worked it in this way. They rested their breasts on the sand, put their beaks under, and lifted. When the fish was raised several inches, they held it with their beaks and pushed their breasts against it, when over it went, down the little pitch they had made.

They could not stop, and they went with it, but at once came back and found enough to pay them for their hard work.

One who really watches birds to see what they are doing will see many actions that show intelligence and reason.
