Alternating incubation behavior by ring-neck doves (Streptopelia risoria)

Abstract

Many avian species exhibit a monogamous breeding system, in which a solitary male and female form a pair bond to rear their offspring. Such a monogamous parenting approach is highly rare within the realm of animal groups and stands as a prominent hallmark of avian behavior. The prevalence of monogamy in the avian mating system is closely linked to their substantial involvement in breeding. In this context, we observed the incubation behavior of two pairs of ring-neck doves (Streptopelia risoria) under a controlled laboratory setting. Our observations showed that there is a pattern of breeding in which individuals take turns, and those who incubate during daylight hours are distinct from those who incubate during the nocturnal period. Interestingly, it is the males who hold the eggs during the daytime. We believe that males are better suited for high-risk daytime incubation, despite our limited sample size. It is also important to note that successful parenting behaviors, such as cooperative incubation, require synchronization of physiological state patterns between pairs and stable social relationships.
