Naturalistic learning and reproduction in ring neck doves (Streptopelia risoria).

Successful reproduction in avian species requires considerable parental care, and for most species the efforts of both parents are necessary for the survival of offspring. Here we make the case that in these species reproductive interactions are enhanced when neurochemical activity reinforces critical stimuli and behaviors through associative learning. Drawing from research on several different species, we describe evidence for the role of associative learning in the reproductive behaviors of ring neck doves (Streptopelia risoria). A hypothetical mechanism involving a combination of classical and operant conditioning is proposed to explain the formation and maintenance of the pair bond, nest fidelity, and incubation behavior. The role of the opiate system in reinforcing various aspects of reproductive behavior in this and other species is discussed.
