摘要

Many proximate factors determine a bird's laying date, including environmental and social stimuli as well as individual responses to internal and external factors. However, the relative importance of these factors has not been experimentally demonstrated. Here we show that (i) large differences in the onset of first clutches between different populations result from variation in different responses to photoperiod and not from variation in responses to any other proximate factors and (ii) the same response mechanism causes maladaptive laying dates in habitats modified by humans.
