| Abstract: | Abstract Plots of oviposition times for an unselected group of 84 female Coturnix using the circular mean time for each bird on a central index time indicated a regularity in the data for individual birds. An analysis of pooled data using a moving average showed agreement with the temporal occurrence of the photoresponsive interval reported in the literature for gonadal development. These data were used to support a modification of existing hypothesis on the control of oviposition and ovulation. |
