我们的实验表明，在蓝山雀（Parus caeruleus）的产卵日期是因果关系的经验，在过去的一年。在雏鸟期，在一年内收到额外的食物的女性产卵后，在第二年与控制鸟类相比，无论在前一年的自然食物丰度的同步程度。结果，它们的育雏时间远远晚于次年雏鸟食物供应的高峰期。蓝山雀对经验的反应是适应性的，它们生活在异质的栖息地，食物的高峰期各不相同，但一旦定居下来，就会在同一地点繁殖。
We experimentally show that in blue tits (Parus caeruleus) egg-laying date is causally linked to experience in the previous year. Females that received additional food in the nestling period in one year laid eggs later in the next year compared with the control birds, whatever the degree of synchronization with the natural food abundance in the previous year. As a result, they raised their brood much later than the peak period of nestling food availability in the next year. The response to experience is adaptive for blue tits, which live in heterogeneous habitats where the peak period of food varies, but once settled will breed at the same location for life.
