Differences in the sexual conditioned behavior of male and female Japanese quail (Coturnix Japonica).
Journal of Comparative Psychology, 1997Co-Authors: German Gutierrez, Michael DomjanAbstract:The conditioned responses of male and female Japanese quail (Coturnix Japonica) were compared in a Pavlovian conditioning procedure in which presentation of a brief conditioned stimulus was immediately followed by the release of a copulation partner. Male quail vigorously approached the conditioned stimulus and were much more likely to enter the compartment housing their copulation partner than were female birds (Experiment 1). In females, sexual conditioning resulted in increased squatting (Experiment 2). This response was the reflection of sexual behavior rather than more general social behavior (Experiment 3). These findings provide the first definitive evidence of sexual learning in female quail and are consistent with the interpretation that sexual conditioning increases sexual arousal or receptivity in both sexes but the increase has different behavioral manifestations in male and female quail.

The behavior of the Japanese or domestic quail Coturnix Japonica.
Neuroscience and biobehavioral reviews, 1997Co-Authors: Andrew D. Mills, Michael Domjan, Lawrence L. Crawford, Jean-michel FaureAbstract:Abstract This paper reviews the literature pertaining to the behavior of the Japanese or domestic quail Coturnix Japonica. Details are given of the classification, characteristics, domestication and the economic and research potential of the species. Further sections deal with sensation and perception (including taste and smell, vision and hearing), maintenance behavior (including feeding and drinking, dust bathing and thermoregulation), development and aging (including vocalization, filial imprinting, sexual imprinting, fear and avoidance responses, sexual maturation and aging), adult learning (including habituation, instrumental conditioning, Pavlovian conditioning and observational learning), photoperiodism, reproductive behavior (including courtship and mating, hormonal control and ontogeny of sexual differentiation, and male and female sexual behavior), parental behavior (including nest-site selection and nest building, incubation behavior and its hormonal control, and hen-chick relationships), and aggressive behavior and dominance (including agonistic behavior and the hormonal control of aggressive behavior)

Learning and male–male sexual competition in Japanese quail (Coturnix Japonica).
Journal of comparative psychology (Washington D.C. : 1983), 1996Co-Authors: German Gutierrez, Michael DomjanAbstract:Male Japanese quail (Coturnix Japonica) were trained individually to discriminate between 2 sounds presented at opposite ends of an outdoor aviary. One of the sounds (the positive conditioned stimulus [CS+]) was associated with the release of a female, and the other (the negative CS [CS-]) was presented alone. Which of the 2 sounds served as the CS+ (and which served as the CS-) was counterbalanced across subjects. The subjects came to approach their CS+ but did not move away from their CS-. After having been conditioned individually, the subjects were tested in pairs, with a single female released after the presentation of a stimulus that was the CS+ for one of the males and the CS- for the other male. During most of these tests, the male for whom the prefemale stimulus was the CS+ copulated with the female before the male for whom the prefemale stimulus was the CS-. These results indicate that learning can have an important role in competition for access to a reproductive partner.

Discriminating the sex of conspecifics by male Japanese quail (Coturnix Coturnix Japonica).
Journal of comparative psychology (Washington D.C. : 1983), 1991Co-Authors: Michael Domjan, Russell D. RavertAbstract:How male Japanese quail (Coturnix Coturnix Japonica) discriminate the sex of conspecifics at a distance was investigated by testing subjects with male and female stimulus birds on the other side of a small window after opportunities to copulate with females and again after repeated exposures to males in the absence of copulatory opportunity. Time spent near the window, frequency of window approaches, duration of window visits, rate of walking near the window, line crossings outside the window area, pecking the window, and crowing were measured. Subjects responded similarly in the presence of male and female stimulus birds during the first test block but discriminated the sex of conspecifics after noncopulatory exposures to males. The discrimination was evident in less locomotion and less crowing in the presence of females as compared with males and, as predicted by a discrimination learning hypothesis, developed largely through a change in responding to males.

A simple PCR method for sexing Japanese quail Coturnix Japonica at hatching
British Poultry Science, 2017Co-Authors: Vincent Coustham, E Godet, Linda BeauclairAbstract:1. The quail is a potentially important avian model for molecular studies; a major drawback is the inability to sex visually before 3 weeks of age. Molecular sexing is therefore an absolute requirement when animals are sampled before that age. 2. A low-cost method using common laboratory equipment based on Allele-Specific Multiplex-Polymerase Chain Reaction was developed to undertake reliable molecular identification of the sex of Coturnix Japonica directly at hatching. 3. This simple method works with down feathers collected from behind the neck of the newly hatched quail and includes internal controls during the PCR to limit risks of error. Males and females can be discriminated on the basis of the presence of one or two amplicons, respectively.

Serum biochemical changes in Japanese quail (Coturnix Coturnix Japonica) experimentally infected with salmonella enterica serovar gallinarum
African Journal of Cellular Pathology, 2015Co-Authors: I. J. Barde, J. O. O. Bale, S. B. Oladele, M. Y. Fatihu, Peterside Kumbish, A. G. Rimfa, J. S. Ahmed, P. A. OkewoleAbstract:Aim: To determine the serum biochemical changes in Japanese quail (Coturnix Coturnix Japonica) experimentally infected with Salmonella enterica serovar Gallinarum Methods: A total of 160 (108 males and 52 females) Japanese quails (Coturnix Coturnix Japonica) were used for the experiment. Four weeks old quails were randomly selected and assigned into four groups (A, B,C and D) of forty quails each. Groups A, B and C were infected with Salmonella enterica serovar Gallinarum per os at the dose of 106,104and102, respectively, while group D served as the control. Sera were used for the determination of biochemical parameters. Results: There were significant changes (P

Effects of enclosure size on sexual behavior of Japanese quail (Coturnix Japonica)
Journal of comparative psychology (Washington D.C. : 1983), 2006Co-Authors: Bennett G. Galef, Sarah J. Watkins, Parastoo SalehiAbstract:The authors determined whether results of experiments on copulatory and affiliative behavior of pairs of Japanese quail (Coturnix Japonica) conducted in a closely confining apparatus would predict behavior in a large enclosure in which female quail could avoid contact with male quail. As found previously in studies of closely confined quail, in a large enclosure containing numerous barriers, both unmated female quail and mated female quail laying unfertilized eggs were more likely to remain near a confined male quail than were mated female quail laying fertilized eggs. Furthermore, the number of copulations that a pair engaged in when closely confined predicted the number of copulations that they engaged in when they were in the large enclosure. Patterns of affiliation and of mating in a confining laboratory apparatus thus predicted behavior in a larger enclosure that provided female quail with opportunity to avoid contact with male quail.

'Culture' in quail: social influences on mate choices of female Coturnix Japonica.
Animal behaviour, 2000Co-Authors: David White, Bennett G. GalefAbstract:We have shown previously that after a focal female Japanese quail, Coturnix Japonica, sees a conspecific male mating, the focal female’s tendency to affiliate and to mate with that male is significantly increased. Here we describe two experiments demonstrating that a focal female quail that has seen a conspecific male mating subsequently shows an enhanced tendency to affiliate not only with that particular male, but also with other males that share his characteristics. The results have important implications for our understanding of the role of social learning in the evolution of male characteristics.

mate choice copying in japanese quail Coturnix Coturnix Japonica
Animal Behaviour, 1998Co-Authors: Bennett G. Galef, David WhiteAbstract:We performed four experiments to examine effects on the mate choices of female Japanese quail, Coturnix Coturnix Japonica, of observing a male mate with another female. Each experiment was conducted in three phases: (1) a pre-test during which subject females were allowed to choose between two males with which to affiliate; (2) an observation phase, in which subject females either watched or did not watch the male they had spent less time near during the pre-test (their 'non-preferred' male) copulate with a 'model' female; and (3) a post-test when subject females again chose between non-preferred and preferred males. Only females that had watched their non-preferred male mate with a model female during the observation phase spent significantly more time affiliating with him during the post-test than they had during the pre-test. Watching mating did not change females' criteria for choosing males, and non-preferred males that had mated recently were no more attractive to females than were non-preferred males that had not done so, unless subject females actually observed the mating take place. The results were consistent with the hypothesis that female quail copy one another's mate choices.
