Data from: Increasing temperature, not mean temperature, is a cue for avian timing of reproduction

Timing of reproduction in temperate zone birds is strongly correlated with spring temperature, with an earlier onset of breeding in warmer years. Females adjust their laying between years to be synchronized with local food sources and thereby optimize reproductive output. However, climate change currently disrupts the link between predictive environmental cues and spring phenology. To investigate direct effects of temperature on the decision to lay, and its genetic basis, we used pairs of Great Tits...
