  • Fig. 1 Incubation calling behavior in relation to incubation stage and ambient temperatures.

    (A) Proportion of nests producing incubation calls on hot days (maximal daily temperature ≥26°C) in relation to the number of days before or after expected hatching date (vertical red line). (B) Probability of pairs emitting incubation calls in relation to maximal daily temperature on the day of recording for nests within 5 days of hatching (green) or either before or after this period (blue). Each data point represents one nest in a recording session.

  • Fig. 2 Nestling mass on day 13 (i.e., at the end of the nestling phase) in relation to nest temperature above ambient.

    (A) Treatment nestlings exposed to incubation calls. (B) Control nestlings exposed to parental contact calls. Raw data are shown, with one data point per nestling. The lines depict the regression line (full) and 95% confidence intervals (dotted).

  • Fig. 3 Probability of calling while begging in relation to nest temperature experienced since hatching (nest temperature above ambient + mean daily maximum temperature) for nestlings that heard incubation calls (green) or control calls (blue) as embryos.

    Each data point represents one nestling.

  • Fig. 4 Effect of incubation calling as late-stage embryos on individuals’ reproductive success and thermal preferences in their first year.

    (A) The number of fledglings produced by females (predicted values from GLM) in relation to the nest temperature (above ambient) that they experienced as nestlings and their mass as 13-day-old nestlings. (B) Observed (red) mean (±SE) temperature above ambient of breeding nest boxes used at adulthood by treatment (“treat”) and control (“cont”) males and females, compared with values expected by chance (gray) given nest box availability and pair composition (two treatment, two control, or mixed partners).
