Models explaining the tree selection probability of Magellanic woodpeckers as a function of the Decay Index Ratio (<i>DIR</i>), which represents the quality of each tree relative to the mean decay stage of all trees available at different time lags (Δt = 0, 1, 2, 3 and 4) and spatial-scales (route vs. local-scale), as explained in the main text.

Model selection was carried out for each period independently, with models being ranked according their DIC values. Models with ΔDIC <2 were considered to be supported. The model with intercept-only (β0) was considered as a 'baseline' or 'null' model.
