_Separate courtship_ may be illustrated by the following cases, the first of which is also interesting as showing that it is not among men alone that the female occasionally becomes the wooer; and the second as showing how early in the scale of animal life a primitive sort of courtship may be found. Concerning a wild duck brought up in captivity Mr. Hewitt says that “After breeding a couple of seasons with her own mallard, it at once shook him off on my placing a male pintail on the water. It was evidently a case of _love at first sight_, for she swam about the newcomer caressingly, though he appeared evidently alarmed and averse to her overtures of affection. From that hour she forgot her old partner. Winter passed by, and the next spring the pintail seemed to have become a convert to her blandishments, for they nested and produced seven or eight young ones.” The second case relates to the landsnail, concerning which Agassiz says: “Quiconque a eu l’occasion d’observer les amours des limaçons ne saurait mettre en doute la séduction déployée dans les mouvements et les allures qui préparent et accomplissent le double embrassement de ces hermaphrodites.” The opportunities for prolonged Courtship being thus given, the question arises, “Do animals, while a-wooing, experience the same feelings as a human lover?” In other words, Are any of the overtones of Romantic Love present in the amorous passion of animals? Several of them no doubt are habitually absent. Animals have not sufficient imagination to meditate consciously on their probable success or failure in Courtship; and this lack of imaginative power excludes those “overtones” which are chiefly dependent on that faculty; notably Sympathy with the beloved’s feelings, Pride of Conquest and Possession, Hyperbolic Adoration, Voluntary Self-Sacrifice for the other, and the Woful Ecstasy of Mixed Moods. That Gallantry, or the Desire to Please, _may_ be present is shown by the words I have italicised in the quotation just made regarding the courtship of vultures, and is further shown by the display of their ornamental plumage by male birds to excite the attention of the female. Exclusiveness of affection is indicated by the occasional indifference of the wooer to every rival; and when we read of the German blackcock’s love-dances, during which, “the more ardent he grows the more lively he becomes, until at last the bird appears like a frantic creature”; and that “at such times the blackcocks are so absorbed that they become almost _blind and deaf_, but less so than the capercailzie,” so that “bird after bird may be shot on the spot, or even caught by the hand”—when we read this, we feel tempted to credit these birds even with those highest and most specialised forms of lover’s madness which lead to oblivion—Self-Sacrifice and Ecstatic Adoration.
