<h2><SPAN name="CHAPTER_VIII" id="CHAPTER_VIII">CHAPTER VIII.</SPAN></h2> <p class="caption3nb">HOW BABY BIRDS ARE FED.</p> <p><span class="smcap">Some</span> of the baby birds are nurslings, like the lambs and colts. They are dependent upon what the parent birds first eat and digest. Others eat just what the <span class="pagenum"><SPAN name="Page_34" id="Page_34">[ 34 ]</SPAN></span> old birds do from the start. Only you will notice that the mother bird pounds and bruises the food she gives to her young, tapping it on the edge of the nest or on a twig or the ground until it is soft enough for the birds to swallow without danger of scratching their tender throats.</p> <p>Linnets, pigeons, humming-birds, and some of the finches, are nurslings. The food is prepared for them by the parent birds, and the young are fed by the old bird's bill. We imagine that the bill of the parent bird is the nursing-bottle. The old birds first eat food themselves, and then work it over in their crops into a sort of paste or milky fluid. Then, when the meal is all ready, they alight on the edge of the nest and feed the babies. We have seen humming-bird mothers feed the babies while poised on their wings above the nest.</p> <p>Perhaps there are four or five finches all clamoring for breakfast, crying, and stretching their little necks up as high as possible. The old bird on the edge of the nest looks at the open mouths of all her babies, and begins at the one she thinks is the hungriest. She puts the nursing-bottle, which is her bill, far down the throat of the nursling, clinging fast to the nest or twig with her toes, and moving her bill up and down, her own throat throbbing all the while.</p> <p>We once saw a humming-bird feed one of her young ones and then fly away. During her absence the little birds changed places in the nest, turning completely around. When the mother came back to finish giving <span class="pagenum"><SPAN name="Page_35" id="Page_35">[ 35 ]</SPAN></span> them their breakfast, she made no mistake, but fed the hungry one, though both had their bills wide open.</p> <p>When the mother has fed one child as much as she thinks is its share, she turns to the next open mouth. In this way she nurses the whole cradleful, who seem never to be satisfied.</p> <div id="fig_10" class="fig_center" style="width: 426px;"> <ANTIMG src="images/fig_10.png" width-obs="426" height-obs="298" alt="" /> <div class="fig_caption">Humming-Bird feeding her Young.</div> </div> <p>We have seen no "runts" or dwarf birds in a family, as are sometimes seen in a nest of pigs or puppies. The parent birds seem to understand, and to see that each baby has its proper share and not a crumb more. They do not love one better than another.</p> <p>Some birds keep on nursing their young long after we think the lazy children are large enough to be looking out for themselves. It would be no better <span class="pagenum"><SPAN name="Page_36" id="Page_36">[ 36 ]</SPAN></span> than they deserve if they had to go hungry sometimes. We think they often must get very hungry before they have learned to work for their board. This is all right, for if the parents kept on supporting them, what useless creatures they would be!</p> <p>We shall tell you after a while about our bird's restaurant. We have seen the young birds follow their mother to the table at this restaurant and stand coaxing for the crumbs. At first the mocking-bird mother picks up the food and puts it in the young bird's mouth, and then she flies away. She has given it only a little, just to show the little bird where the food is and how to pick it up himself. There he will stand, looking at the cookie crumbs and teasing as loud as he can, but the mother will not come back. She sits in a tree near by watching to see how her bird child learns his first lesson at helping himself.</p> <p>After a while, the young bird gets very hungry and begins pecking for the crumbs. At first he makes very awkward attempts at grabbing a crumb, but he succeeds at last and swallows the rest of his breakfast. We laugh, sitting in the shade watching him, and we think his mother is laughing too, in the tree above.</p> <p>Those birds that do not nurse their young with liquid food are supposed to give them water as well as food, by bringing it to them in their beaks, though we have not seen them do so. Probably the babies are fed on soft worms and fruits until they have cut their first teeth.</p> <p><span class="pagenum"><SPAN name="Page_37" id="Page_37">[ 37 ]</SPAN></span></p> <p>How can the little things eat hard seeds and bones before they have any teeth? Does it make you smile and wonder when we speak of baby birds cutting their teeth? Don't you suppose birds have teeth? Of course they have.</p> <p>Every bird has a set of false teeth working out of sight. Birds never have the toothache, and they do not have to be brave and hold still while somebody pulls their teeth out. They can have a new set of teeth as often as they need them, without paying a good price to the dentist.</p> <p>Look along the path and you will see these teeth, lying as thick as hail in some places. Little sharp stones, coarse gravel, and fine sand,&mdash;these are the bird's teeth. When a bird picks them up, he swallows them, and they go, without any trouble, right where they belong, down to a kind of pouch or pocket called the gizzard. This pocket is lined with very tough muscles. These muscles or rings look something like a fluting-iron or washboard, and as they move they set the teeth or little stones to rolling against the food in such a way that it is soon ground into bits, or rather into paste.</p> <p>It takes a baby bird a long time to learn to pick up anything with its bill. It will peck and peck at the food without being able to touch it, as we have seen many birds do when brought up in a cage, and as the little mocking-birds do at the garden table.</p> <p>Once we had some pet orioles, and before we noticed <span class="pagenum"><SPAN name="Page_38" id="Page_38">[ 38 ]</SPAN></span> what he was doing, one of them made his bill look like a hawk's bill, all curved or crooked. He had pecked so hard at the food on the board floor of his cage that the hard taps had bent his soft bill out of shape, and it remained so after the bird had grown up. We have seen a blue jay and a thrush and a towhee, each with his beak out of shape, twisted to one side or broken. This must have been done when they were little. Birds, like other people, must have the right start if they are to be beautiful when they are older.</p> <div id="fig_11" class="fig_center" style="width: 441px;"> <ANTIMG src="images/fig_11.png" width-obs="441" height-obs="320" alt="" /> <div class="fig_caption"><span class="smcap">Blue Jay.</span></div> </div> <p>Though young birds can see the food before them, they have to try a long while before they know exactly how to take hold of it. They make us think of real <span class="pagenum"><SPAN name="Page_39" id="Page_39">[ 39 ]</SPAN></span> babies trying to pick up some toy with their fat little hands. A bird's bill at first is very soft, like a baby's bones. If you feel of it, you will see that to the touch it is like a piece of rubber.</p> <p>The difficulty is really more with the bird's eyes than with his bill, for it seems that, although he sees the food which he wants to eat, he cannot measure the distance correctly until he has learned how to see straight and aim right.</p> <div class="poem"><div class="stanza"> <span class="i0">"Let me look in your mouth, little bird;<br/></span> <span class="i3">How many white teeth have you?<br/></span> <span class="i1">No teeth? then how do you chew your food?<br/></span> <span class="i3">Be honest and tell me true."<br/></span></div> <div class="stanza"> <span class="i0">"My teeth are all out of sight, little boy,<br/></span> <span class="i3">They are hard and white and firm;&mdash;<br/></span> <span class="i1">Out of sight, but they grind the seeds like a mill,<br/></span> <span class="i3">And the bug, and the nice fat worm."<br/></span></div> </div> <div class="fig_center" style="width: 132px;"> <ANTIMG src="images/bar_dot.png" width-obs="132" height-obs="10" alt="bar with diamond" /></div> <div style="break-after:column;"></div><br />
