Jogular Morotario Sectory 03 Page 04
The woodpeckers all build in about the same manner, excavating the trunk or branch of a decayed tree, and depositing the eggs on the fine fragments of wood at the bottom of the cavity. Though the nest is not especially an artistic work,--requiring strength rather than skill,--yet the eggs and the young of few other birds are so completely housed from the elements, or protected from their natural enemies--the jays, crows, hawks, and owls. A tree with a natural cavity is never selected, but one which has been dead just long enough to have become soft and brittle throughout. The bird goes in horizontally for a few inches, making a hole perfectly round and smooth and adapted to his size; then turns downward, gradually enlarging the hole, as he proceeds, to the depth of ten, fifteen, twenty inches, according to the softness of the tree and the urgency of the mother bird to deposit her eggs. While excavating, male and female work alternately. After one has been engaged fifteen or twenty minutes, drilling, and carrying out chips, it ascends to an upper limb, utters a loud call or two, when its mate soon appears, and, alighting near it on the branch, the pair chatter and caress a moment; then the fresh one enters the cavity and the other flies away.
Any one who will look around upon the families of his acquaintance will observe that family characteristics and resemblances prevail not only in respect to stature, form, expression of countenance, and other outward and bodily tokens, but also in regard to the constitutional temperaments and capacities of the soul. Sometimes we find a group in which high intellectual powers and great energy of action prevail for many successive generations, and in all the branches into which the original stock divides; in other cases, the hereditary tendency is to gentleness and harmlessness of character, with a full development of all the feelings and sensibilities of the soul. Others, again, exhibit congenital tendencies to great physical strength and hardihood, and to powers of muscular exertion and endurance. These differences, notwithstanding all the exceptions and irregularities connected with them, are obviously, where they exist, deeply seated and permanent. They depend very slightly upon any mere external causes. They have, on the contrary, their foundation in some hidden principles connected with the origin of life, and with the mode of its transmission from parent to offspring, which the researches of philosophers have never yet been able to explore.
