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.

[Illustration] Young bluebirds taking their first walk. {9} 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.
