In its habits it is shy; and its voice may be often heard whilst the eye seeks in vain to find the bird itself. Its food consists of caterpillars and various insects.
The female cuckoo makes no nest, and takes no care of her young. How do you suppose she does? Having a wide bill, she takes up in it one of her eggs, which she puts in the nest of some other bird that feeds on insects.
The strange nurses to whom the cuckoo confides her young become not only good mothers to them, but neglect their own children to take care of the young cuckoos.
As the young cuckoo thrives and grows strong, he thrusts the other birds out of the nest, so that he may have all the room to himself. For five weeks or more his adopted mother supplies him with food.
