The really sympathetic notes of our fowls are uttered in their ordinary intercourse. Here the gradations of sounds have a range and fineness which, it seems to me, we can observe in no other creature below the level of man. Attention, astonishment, fear, commonplace distress, exultation, and agony are all set forth with cries which we, in a way, recognize as appropriate. Although some of these sounds relate to the larger experiences of the creatures, the most instructive of them are uttered in their ordinary intercourse, where they clearly maintain a kind of consensus in the flock by unending small bits of emotional speech, the notes being shaded in a wonderful way. These fine variations of utterance can sometimes be observed to be related to slight differences of situation. Thus the cackle of a hen when she leaves her nest after laying an egg is quite different from that which is made by the same hen when, during the period of incubation, she quits her eggs in search of food and water. It is not unlikely that the eminent domesticability of our common fowls is in a way associated with the singular variety of their notes. This variety indicates that the creatures are in constant and effective communication with one another; in a word, they are very sympathetic. With this intellectual helpfulness naturally goes the love of the domicile and a disposition to submit to control. So nice and well understood are the differences between the sounds which these birds give forth, and so well are their notes appreciated by their companions, that the creatures may well be said to have a language. Though it probably conveys only emotions and not distinct thoughts, it still must be regarded as a certain kind of speech. The modes of expression indicate that in this creature, as in the other feathered forms, the intellectual life consists largely in the movements inspired by the emotions. On the rational side our fowls seem weaker than many other less interesting species. In their nesting and other habits there are no evidences of constructive ingenuity; and in all my observations on them I have never seen any evidence which showed either considerable powers of memory or a capacity to act in any complicated way with reference to an end. It is evident, however, that they make a very good classification of the world about them. They have, for the limited field over which they roam, a keen topographic sense; they never are lost, and this in connection with their sympathetic homing instinct prevents them from wandering from their accustomed places to take up again with a wilderness life.
