Mean values across all cycles are given for the 5 days before the fertile period (Pre-Fertile), the four day fertile period (Fertile) and the five days following the fertile period (Post-fertile). Values were first averaged across all cycles for each day with respect to the ovulation window, then across all days within each respective period. For rate behaviours, values given here are n/hr. For binary variables, values given are proportion of copulations in which the behaviour occurred. P values of the statistical test employed are given (see text for full statistical results).
