Young bluebirds taking their first walk.
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.
Now is the time to have ready on top of the grape arbour, or under the eaves of the barn, or nailed up in the apple tree, or set up on poles, the little one-roomed houses that bluebirds are only too happy to occupy. More enjoyable neighbours it would be hard to find. Sparrows will fight for the boxes, it is true, but if there are plenty to let, and the sparrows are persistently driven off, the bluebirds, which are a little larger though far less bold, quickly take possession. Birds that come earliest in the season and feed on insects, before they have time to multiply, are of far greater value in the field, orchard, and garden than birds that delay their return until warm weather has brought forth countless swarms of insects far beyond the control of either bird or man. Many birds would be of even greater service than they are if they received just a little encouragement to make their homes nearer ours. They could save many more millions of dollars' worth of crops for the farmers than they do if they were properly protected while rearing their ever-hungry families. As two or even three broods [{11}] of bluebirds may be raised in a box each spring, and as insects are their most approved baby food, you see how much it is to our interest to set up nurseries for them near our homes.
But when people are not thoughtful enough to provide them before the first of March, the bluebirds hunt for a cavity in a fence rail, or a hole in some old tree, preferably in the orchard, shortly after their arrival, and proceed to line it with grass. From three to six pale blue eggs are laid. At first the babies are blind, helpless, and almost naked. Then they grow a suit of dark feathers with speckled, thrush-like vests similar to their cousin's, the baby robin's; and it is not until they are able to fly that the lovely deep blue shade gradually appears on their grayish upper parts. Then their throat, breast, and sides turn rusty red. While creatures are helpless, a prey for any enemy to pounce upon, Nature does not dress them conspicuously, you may be sure. Adult birds, that are able to look out for themselves, may be very gaily dressed, but their children must wear sombre clothes until they grow strong and wise.
Young bluebirds are far less wild and noisy than robins, but their very sharp little claws discourage handling. These pointed hooks on the ends of their toes help them to climb out of the tree hollow, that is their natural home, into the big world that their presence makes so cheerful.
