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).
孵化后，雌雄斑鸠都会以与孵化前孵蛋时大致相同的方式趴在幼雏身上，但这项研究表明，偏好的刺激因素会随动物的状态而变化。在经验丰富和缺乏经验的雌雄斑鸠正常繁殖周期的孵化第1天、第4天、第10天和第13天以及孵化后的第二天，进行了幼雏 - 蛋同时选择测试。在整个周期中，缺乏经验的斑鸠比经验丰富的斑鸠更有可能选择蛋（P小于0.005），总体而言，在孵化早期和孵化后选择蛋的可能性更大（P小于0.005）。
