To examine how warming spring temperatures affect the timing of egg laying in great tits relative to the peak food demands of their offspring.
Monitored egg-laying dates and reproductive performance in a great tit (Parus major) population over a 23-year period.
Tracked concurrent changes in spring temperatures, vegetation phenology, and natural selection pressures on avian breeding timing.
Egg-laying dates in the great tit population failed to advance over the 23-year study period despite rising spring temperatures.
Natural selection favoring earlier egg laying intensified over time due to an advancing food peak, indicating an adaptive mismatch caused by disconnected cues.
