Appendix S4. Minimal phylogenetic generalized least squares models for explaining the variation in immune variables between species in relation to incubation period, fledging period, body mass, life-history and ecological traits. The results are for the subset of data limited to species with more than one observation. The values are β (SE) and t. Significant P-values are shown in bold and the values are: * P < 0.05, **P < 0.01, ***P < 0.001. The near significant values (P < 0.1) are shown in superscripts.

The minimal models were obtained by eliminating non-significant predictors from the full models in a backward stepwise manner based on the largest P-value. Model intercepts implement the first level of each factor (i.e. resident species in the case of migratory behaviour). All other levels of the candidate factor are compared to the level implemented in the intercept.

Model intercepts implement the first level of each factor (i.e. terrestrial species in the case of habitat and resident species in the case of migratory behaviour). All other levels of the candidate factor are compared to the level implemented in the intercept.

1No significant difference between groups riparian and aquatic for heterophils (β (SE) = –0.35 (0.28), t = –1.22, P = 0.2267), lymphocytes (β (SE) = –0.68 (0.35), t = –1.93, P = 0.0563), WBCs (β (SE) = –0.57 (0.39), t = –1.46, P = 0.1464) and lysis (β (SE) = –0.54 (0.27), t = –1.98, P = 0.0514), and significant difference for agglutination (β (SE) = –0.71 (0.30), t = –2.35, P = 0.0212).

Appendix S6. Minimal phylogenetic generalized least squares models for explaining the variation in immune variables between species in relation to incubation period, relative incubation period and body mass. Life-history and ecological traits which significantly explained the immune traits (see Table 1) were included in the models to control their effects. Values are β (SE) and t. Significant P-values are shown in bold and the values are: * P < 0.05, **P < 0.01, ***P < 0.001. The near significant values (P < 0.1) are shown in superscripts.
