Table 2. Coefficients (Mean, SD, and 2.5th and 97.5th percentiles) of the variables included in the models of the probability of detecting the Grey Shrike-thrush on a visit to a site, as a function of traffic noise (Models 1 and 3) and traffic volume (Model 2), with the deviance information criterion (DIC) and receiver-operating characteristic curve (AUC) values for models 1 and 2. Models 1 and 2 include data from all 58 study sites, whereas Model 3 includes data from the 19 study sites in which traffic volume was < 200 vehicles/d.
