Notes: The full model was significantly different from a null model containing only the random factor “nest ID” (χ² = 28.9, df = 6, P < 0.001). Multiple comparisons between levels of the factor “location/year” were performed using Tukeyʼs contrasts with single-step P-value adjustment. Significant P-values (P < 0.05) are shown in bold
