Figure S1. Number of occupied split-plots per species, treatment and year.; Figure S2. Number of territories per species, treatment and year.; Figure S3. Mean number (± 95% CrI) of territories and species per split-plot according to treatment and year with the plotted corresponding posterior distribution.; Figure S4. Guild specific mean number of territories and species (± 95% CrI) according to treatment and year. Plotted are as well the corresponding posterior distributions.

Figure S1: Number of split-plots in which each species was detected at least once during the three breeding-bird censuses, separately for disturbed and control split-plots. In 2014 (a) a species could be seen in a maximum of 6 split-plots while in 2015 (b) the maximum was 12. For species abbreviations see electronic supplementary material table S1.; Figure S2: Number of territories per species for disturbed and control split-plots in the six plots of 2014 (a) and in the 12 plots of 2015 (b). For each year, the maximum number of territories per species detected in each split-plot out of the three censuses was taken and summed over all split-plots. For species abbreviations see electronic supplementary material table S1.; Figure S3: Effect of experimental human disturbance on the number of territories (a,b) and species richness (c,d) per split-plot (4.7 ha) according to year and migration type: the graphs (a) and (c) include only the resident and short-distance migrant species, while the graphs (b) and (d) only the long-distance migrants. Note the different y-axes. Represented are mean fitted values with 95% credible intervals (table 1) as well as the corresponding posterior distributions. The posterior probability (PP) shows the strength of the difference between disturbed and control split-plots.; Figure S4: Effect of experimental human disturbance on the number of territories and species richness per split-plot (4.7 ha) according to (a) nesting-guild (cavity, ground and open-cup nesters), (b) sensitivity (based on flight initiation distance (FID); high = FID > median FID, low = FID ≤ median FID), and (c) foraging guild (ground and above ground) in 2014 and 2015, respectively (only for resident and short distance migrants). Represented are mean fitted values with 95% credible intervals (Electronic supplementary material table S2-S4) as well as the corresponding posterior distributions and the posterior probability (PP) that the differences between disturbed and control split-plots are different from zero.
