Role of mate's previous experience in ring dove hormone-induced incubation

Progesterone-induced incubation was examined in 40 pairs of adult ring doves, differing in their previous reproductive experience (courtship vs. nest building) and the previous reproductive experience of their mates (courtship vs. nest building) during testing. Only the previous experience of the experimental subject significantly affected the establishment of incubation during the 24-hr test period. More doves experienced with nest building established incubation than did courtship-experienced doves. The latency to enter the nest area and the latency to stand on the nest were affected by both the previous breeding experience of the subject and the previous breeding experience of its mate. Nest-building-experienced mates decreased the latencies of courtship-experienced subjects, and courtship-experienced mates increased the latencies of nest-building-experienced doves. Males were not more affected by their mates' experience than were females. Time spent on the nest was affected only by the subject's previous experience and sex. While the hypothesis that the behavior of the mate can affect a dove's progesterone-induced incubation was not confirmed, the mate's behavior can affect some of the components of nest responsiveness.
