尽管已知生长过程中经历的条件会影响体型或蛋的大小，但只有繁殖时发生的环境条件才被证明会影响鸟类的产蛋量。我们在此表明，生命早期经历的环境条件会影响圈养斑胸草雀（Taeniopygia guttata）和野生大山雀（Parus Major）的窝产数。不仅直接繁殖季节之外的因素会影响窝数，而且窝数控制机制也会永久受到个体发育期间经历的条件的影响。
Only environmental conditions occurring at the time of breeding have been shown to affect clutch size in birds, even though conditions experienced during growth are known to affect body size or egg size. We show here that environmental conditions experienced during early life can affect clutch size in captive zebra finches (Taeniopygia guttata) and wild great tits (Parus major). Not only do factors outside the immediate breeding season affect clutch size, but clutch size control mechanism is permanently influenced by conditions experienced during ontogeny.
