GLMs explaining the occupancy of cavities by each species as a function of cavity traits, cover of forest canopy, distance to the nearest street, distance to the nearest occupied cavity (D), and aggregation of occupied cavities around the focal one (A).

Variables describing social environments (A and D) were obtained considering cavities occupied by the same species (intraspecific; Aintra, Dintra) and by the ring-necked parakeet (Ainter, Dinter). The species involved in interspecific significant effects (Ainter, Dinter) was always the ring-necked parakeet, except in the case of the model obtained for this species, where Ainter corresponds to the aggregation regarding greater noctules. Signs between brackets indicate positive or negative effects of variables on the probability of cavity occupancy. χ2 values are given for each variable; *: p<0.05, **: p<0.01, ***p<0.001; % dev: percentage of deviance explained.
