HOW A FLICKER FEEDS HER YOUNG 1
ОглавлениеAs the house of the woodpecker has no windows and the old bird very nearly fills the doorway when she comes home, it is hard to find out just how she feeds her little ones. But one of our best naturalists has had the opportunity to observe it, and has told what he saw.
A flicker had built a nest in the trunk of a rather small dead tree which, after the eggs were hatched, was accidentally broken off just at the entrance hole. This left the whole cavity exposed to the weather; but it was too late to desert the nest, and impossible to remove the young birds to another nest.
When first visited, the five little birds were blind, naked, and helpless. They were motherless, too. Some one must have killed their pretty mother; for she never came to feed them, and the father was taking all the care of his little family. When disturbed the little birds hissed like snakes, as is the habit of the callow young of woodpeckers, chickadees, and other birds nesting habitually in holes in trees. When they were older and their eyes were open, they made a clatter much like the noise of a mowing-machine, and loud enough to be heard thirty yards away.
The father came at intervals of from twenty to sixty minutes to feed the little ones. He was very shy, and came so quietly that he would be first seen when he alighted close by with a low little laugh or a subdued but anxious call to the young. “Here I am again!” he laughed; or “Are you all right, children?” he called to them. “All right!” they would answer, clattering in concert like a two-horse mower.
As soon as they heard him scratching on the tree-trunk, up they would all clamber to the edge of the nest and hold out their gaping mouths to be fed. Each one was anxious to be fed first, because there never was enough to go round. There was always one that, like the little pig of the nursery tale, “got none.” When he came to the nest, the father would look around a moment, trying to choose the one he wanted to feed first. Did he always pick out the poor little one that had none the time before, I wonder?
After the old bird had made his choice, he would bend over the little bird and drive his long bill down the youngster’s throat as if to run it through him. Then the little bird would catch hold as tightly as he could and hang on while his father jerked him up and down for a second or a second and a half with great rapidity. What was he doing? He was pumping food from his own stomach into the little one’s. Many birds feed their young in this way. They do not hold the food in their own mouths, but swallow and perhaps partially digest it, so that it shall be fit for the tender little stomachs.
While the woodpecker was pumping in this manner his motions were much the same as when he drummed, but his tail twitched as rapidly as his head and his wings quivered. The motion seemed to shake his whole body.
In two weeks from the time when the little birds were blind, naked, helpless nestlings they became fully feathered and full grown, able to climb up to the top of the nest, from which they looked out with curiosity and interest. At any noise they would slip silently back. A day or two later they left the old nest and began their journeys.
