Dominance rank and offspring sex ratios in domestic fowl
Article Abstract:
The dominance rank of male and female domestic chicken fails to influence the sex ratios of their progeny. Twenty-four dominant and 24 submissive male chickens are mated with 8 females over a period of 3 weeks each. Females mating with submissive males in the 1st trial show an increase in overall sex ratio variability between trials. This effect is not seen in females mating with dominant males first. Although results reject the hypothesis that females must alter the sex ratio of their progeny based on their dominance status or that of their mates, the status of the male may influence sex ratios.

Female mate choice and male behaviour in domestic fowl
Article Abstract:
Paired choice tests were used in the investigation of the traits and behavior that female domestic chickens, Gallus gallus domesticus, prefer among males during courtship displays. Among the six morphological and five behavioral traits, wingflapping was the only significant variable that predicted rooster success in attracting hens. Hens prefer males with high wingflapping rates. A relative choice mechanism appears to be at work during the investigation.

Mate attendance and copulatory behaviour in western bluebirds: evidence of mate guarding
Article Abstract:
Copulatory behavior and mate attendance is a process by which the males protect their paternity, in the western bluebird, Sialia mexicana. The male bluebird copulates with its mate, 60 days before laying till the time of incubation, at a steady rate. Within-pair copulation increases with the increase in proximity of male and female bluebirds. The male bluebirds increases copulatory access and foil extra pair copulations by the process of mate guarding.
