  1. Models are LMMs. Reference levels: treatment = control group, origin = rural birds. For each parameter we show the estimated mean, the lower and upper 95% CI and the p-value calculated based on MCMC (pMCMC). Non-significant interactions were sequentially removed (empty cells). Significant results are printed in bold.
