Shown are the number of georeferenced sites used to build the distribution model; two measures of model performance: (i) the area under the receiver operator curve (AUC) for full models and for test data sets (40% of the full data set), and (ii) the P-value from a one-tailed binomial test on the Maxent extrinsic omission rate and proportional predicted area (Anderson et al. 2002), where significant P-values indicate high model performance; the most important environmental predictor variables as assessed by a jackknifing procedure, where the variable either is used on its own or is the only one omitted from the data set. See Table S1 for information on the environmental variables.

WBWC, wedge-billed woodcreeper; MFP, masked flowerpiercer; SNFC, streak-necked flycatcher; Cb, Carollia brevicauda; Cc, Carollia castanea; Cp, Carollia perspicillata; Pw-n, Pristimantis w-nigrum; SRTM, Shuttle Radar Topography Mission.
