The transition from sitting on eggs to sitting on young in ring doves, Streptopelia risoria: squab-egg preferences during the normal cycle.
Ring doves of both sexes sit on young squabs after hatching in much the same manner as they sit on eggs before hatching, but this study demonstrates that the preferred stimulus varies with the state of the animal. A simultaneous squab--egg choice test was given on days 1, 4, 10, and 13 of incubation and on the day following hatching in normal reproductive cycles of experienced and naïve male and female ring doves. Naïve doves were more likely than experienced doves to choose eggs throughout the cycle (P less than 0-005) and, overall, eggs were more likely to be chosen during early incubation and squabs posthatching (P less than 0-005).
