ravens can talk is a well-known fact, but instances are known where other kinds of birds have learned to speak. Russ, for instance, in his book on ornithology, tells about a canary, owned by an actress, which was capable of speaking some words distinctly.
Other birds have a special liking for certain sounds—owls, for instance, like the tolling of bells. Nicolardot says that a special variety of owl, the "tower-owl," which preferably nests in bell-towers of churches, closely imitates in its cry the sound given out by bells. He also states that it is a comparatively easy matter, calling only for a little trouble and patience, to teach the green-finch and the yellow thrash to talk. Song-birds especially are said to be capable of a musical education much more extensive than they commonly receive nowadays. They are said not only to be able to repeat short melodies whistled to them, but also to sing to the accompaniment of instruments. Maximus, of Tyre, relates, in his "Philosophical Conversations" (translated by Torme), that a certain man, who devoted much of his time and attention to animals, had kept a number of birds of different kinds in his room. Every morning during the beginning of their captivity they sang and chirped—each in its own way—giving rise to much noise and great confusion. In a comparatively short time, however, this man had succeeded in training his birds so that they joined him in making music. He played the flute, and the birds accompanied his playing with their voices, at certain passages all singing correctly in chorus. The responsibility for the truth of this story we must leave to the narrator; however, it is a fact that, in the musical training of birds, wonderful things may be done.
During the time of Napoleon III, there was at Paris a so-called charmeur who came every noon into the garden of the Tuileries and fed the birds of all kinds. The animals knew him by sight, and came to him at once. He could call them individually, and they would perch on his fingers, and, if he whistled certain signal-notes for them, they would repeat these clearly and distinctly.
In these days we are ever seeking and searching; we penetrate deeply into all domains of Nature, and believe ourselves to be approaching to a more true conception of the world about us. But rarely has it been seriously attempted to study the voices of Nature, which form so important a chord in the great concert of creation. Undoubtedly there is here yet much that lies unrevealed, and that is well worth attentive study and investigation. Perchance this might lead to important conclusions concerning the great secret of life in its organic function, which nowhere draws a sharp line between the animal and the vegetable kingdom, and which joins the latter by insensible gradations to the mineral world. The first attempt in this direction has been made by Nicolardot with his work, and this well merits our interest and appreciation.—Translated for the Popular Science Monthly from Ueber Land und Meer.
