separated from the female who would take the passive part (on the rare occasions when homosexual relations occurred) with a fresh male.[7]
Homosexuality appears to be specially common among birds. It was among birds that it attracted the attention of the ancients, and numerous interesting observations have been made in more recent times. Thus Selous, a careful bird-watcher, finds that the ruff, the male of the Machetes pugnax, suffers from sexual repression owing to the coyness of the female (the reeve), and consequently the males often resort to homosexual intercourse. It is still more remarkable that the reeves also, even in the presence of the males, will court each other and have intercourse.[8] We may associate this with the high erotic development of birds, the difficulty with which tumescence seems to occur in them, and their long courtships.
Among the higher animals, again, female monkeys, even when grown up (as Moll was informed), behave in a sexual way to each other, though it is difficult to say how far this is merely in play. Dr. Seitz, Director of the Frankfurt Zo?logical Garden, gave Moll a record of his own careful observations of homosexual phenomena among the males and females of various animals confined in the Garden (Antelope cervicapra, Bos Indicus, Capra hircus, Ovis steatopyga).[9] In all such cases we are not concerned with sexual inversion, but merely with the accidental turning of the sexual instinct into an abnormal channel, the instinct being called out by an approximate substitute, or even by diffused emotional excitement, in the absence of the normal object.
It is probable, however, that cases of true sexual inversion--in which gratification is preferably sought in the same sex--may be found among animals, although observations have rarely been made or recorded. It has been found by Muccioli, an Italian authority on pigeons, that among Belgian carrier-pigeons inverted practices may occur, even in the presence of many of the other sex.[10] This seems to be true inversion, though we are not told whether these birds were also attracted toward the opposite sex. The birds of this family appear to be specially liable to sexual perversion. Thus M.J. Bailly-Maitre, a breeder of great knowledge and a keen observer, wrote to Girard that "they are strange creatures in their manners and customs and are apt to elude the most persistent observer. No animal is more depraved. Mating between males, and still more frequently between females, often occurs at an early age: up to the second year. I have had several pairs of pigeons formed by subjects of the same sex who for many months behaved as if the mating were natural. In some cases this had taken place among young birds of the same nest, who acted like real mates, though both subjects were males. In order to mate them productively we have had to separate them and shut each of them up for some days with a female."[11] In the Berlin Zo?logical Gardens also, it has been noticed that two birds of the same sex will occasionally become attached to each other and remain so in spite of repeated advances from individuals of opposite sex. This occurred, for instance, in the case of two males of the Egyptian goose who were thus to all appearance paired, and always kept together, vigorously driving away any female that approached. Similarly a male Australian sheldrake was paired to a male of another species.[12]
Among birds generally, inverted sexuality seems to accompany the development of the secondary sexual characters of the opposite sex which is sometimes found. Thus, a poultry-breeder describes a hen (colored Dorking) crowing like a cock, only somewhat more harshly, as a cockerel crows, and with an enormous comb, larger than is ever seen in the male. This bird used to try to tread her fellow-hens. At the same time she laid early and regularly, and produced "grand chickens."[13] Among ducks, also, it has occasionally been observed that the female assumes at the same time both male livery and male sexual tendencies. It is probable that such observations will be multiplied in the future, and that sexual inversion in the true sense will be found commoner among animals than at present it appears to be.
Traces of homosexual practices, sometimes on a large scale, have been found among all the great divisions of the human race. It would be possible to collect a considerable body of evidence under this head.[14] Unfortunately, however, the travellers and others on whose records we are dependent have been so shy of touching these subjects, and so ignorant of the main points for investigation, that it is very difficult to discover sexual inversion in the proper sense in any lower race. Travellers have spoken vaguely of crimes against nature without defining the precise relationship involved nor inquiring how far any congenital impulse
