Excerpt from The Early Life of the Young CuckooAlthough we have accomplished this much, we have not yet proved in any way why the egg is so very small in comparison with the size of the bird, but my friend, Mr. John Craig, to whom I shall shortly refer, has, so far as I am aware, produced the best explanation of this by stating that he con siders it is for the purpose of quick incubation and to allow the egg to be deposited in birds' nests which are smaller than the Cuckoo, and also to allow the Cuckoo to carry the egg in her bill to its destination without breaking it.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
