Abstract

It has been suggested that in monogamous species a female will protect herself from mate desertion by withholding copulation until she is assured of the male's parental care. The ring dove (Streptopelia risoria) is a monogamous species whose females copulate with males frequently during prelaying phase. In this study we demonstrate that copulations did not result in fertilization unless they took place contiguous to the pre-ovulatory hormonal state of the female which was brought about only if the male courted the female for a sufficient period of time. Thus, in this species, ovulation and therefore fertilization was dependent on the male's presence regardless of how often copulation took place, insuring that the male must make a time commitment to guarantee paternity.
