When our American robin comes out of the {6} turquoise blue egg that his devoted mother has warmed into life, he usually finds three or four baby brothers and sisters huddled within the grassy cradle. In April, both parents worked hard to prepare this home for them. Having brought coarse grasses, roots, and a few leaves or weed stalks for the foundation, and pellets of mud in their bills for the inner walls (which they cleverly managed to smooth into a bowl shape without a mason's trowel), and fine grasses for the lining of the nest, they saddled it on to the limb of an old apple tree. Robins prefer low-branching orchard or shade trees near our homes to the tall, straight shafts of the forest. Some have the courage to build among the vines or under the shelter of our piazzas. I know a pair of robins that reared a brood in a little clipped bay tree in a tub next to a front door, where people passed in and out continually. Doubtless very many birds would be glad of the shelter of our comfortable homes for theirs if they could only trust us. Is it not a shame that they cannot? Robins, especially, need a roof over their heads. When they foolishly saddle their nest on to an exposed limb of a tree, the first heavy rain is likely to soften the mud walls, and wash apart the heavy, bulky structure, when "Down tumble babies and cradle and all." {7} It is wiser of them to fit the nest into the supporting crotch of a tree, as many do, and wisest to choose the top of a piazza pillar, where boys and girls and cats cannot climb to molest them, nor storms dissolve their mud-walled nursery. There are far too many tragedies of the nests after every heavy spring rain. Suppose your appetite were so large that you were compelled to eat more than your weight of food every day, and suppose you had three or four brothers and sisters, just your own size, and just as ravenously hungry. These are the conditions in every normal robin family, so you can easily imagine how hard the father and mother birds must work to keep their fledglings' crops filled. No wonder robins like to live near our homes where the enriched land contains many fat grubs, and the smooth lawns, that they run across so lightly, make hunting for earth worms comparatively easy. It is estimated that about fourteen feet of worms (if placed end to end) are drawn out of the ground daily by a pair of robins with a nestful of babies to feed. When one of the parents alights near its home, every child must have seen the little heads, with wide-stretched, yellow bills, pop up suddenly like Jacks-in-the-box. How rudely the greedy babies push and jostle one another to get the most dinner, and how noisily they clamour for it! Earth worms are the staff of {8} life to them just as bread is to children, but robins destroy vast quantities of other worms and insects more injurious to the farmers' crops, so that the strawberries and cherries they take in June should not be grudged them.
