Whether you live in the heart of a great city or in the open country, you ought to begin this fall to learn the names and habits of the birds and beasts (snakes, lizards, turtles, toads!) that live wild in your region. Even when all the summer birds have gone south for the winter, there will remain in your woods and fields crows, jays, juncos, tree sparrows, chickadees, kinglets, nuthatches, screech owls, barred owls,—perhaps even snowy owls,—quails, partridges, goldfinches, with now and then a flock of crossbills, snow buntings, and other northern visitors, and even a flicker, robin, and bluebird left over from the fall migrations. These are plenty to begin on; and yet, as they are so few, compared with the numbers of the summer, the beginner’s work is thus all the easier in the autumn.

You should go out one of these frosty mornings for chestnuts, if they grow in your woods; or for “shagbarks,” if you live in New England; for black walnuts, if you live in the Middle States; for pecan nuts, if you live in the Gulf States; for butternuts, if you live in the states of the Middle West; for—what kind of nuts can you not go for, if you live in California where they make everything grow! It matters little whether you go for paper-shelled English walnuts or for plate-armored pignuts so long as you go. It is the going that is worth while.

You ought to go “cocooning” this fall—to sharpen your eyes. But do not go often; for once you begin to look for cocoons, you are in danger of seeing nothing else—except brown leaves. And how many brown leaves, that look like cocoons, there are! They tease you to vexation. But a day now and then “cocooning” will do you no harm; indeed, it will cultivate your habit of concentration and close seeing as will no other kind of hunting I know.
Bring home with you the big brown silky cocoons of cecropia—the largest cocoon you will find, lashed all along its length to its twig, and usually near the ground. Look on the black cherry, the barberry, sassafras, and roadside and garden trees for the harder, whiter cocoon of the promethea moth. This hangs by its tip, because the caterpillar has begun his house by using the leaf, spinning it into the cocoon as part of its walls, much as does the wretched “brown-tail.” The gray cocoons, or rather nests, of this “brown-tail” moth you must bring home to burn, for they are one of our greatest pests. You will find them full of tiny caterpillars as you tear them open.
Bring home your collection and, with the help of such a book as “Moths and Butterflies” by Mary C. Dickerson, identify them and hang them up for their “coming out” in the spring.
