Table 1.

Top performing models describing noctule migration departure all contain variable interactions instead of the variables themselves. ΔAICc notes the change in Akaike information criterion corrected for small sample sizes from an interaction model. See electronic supplementary material 2 for full model summaries. Bat ID was always added as random effect.
