Table 4 Logistic regression results for covariates predicting whether migrating purple martins will cross, or detour around, waterbodies. Tailwind is the wind assistance (m/s) in the optimal direction of travel; Water:Land refers to distance saved by crossing a waterbody (higher ratio = less distance saved), and DayOrNight is time of day that flights were initiated. CI = lower and upper Bayesian credible intervals. Continuous variables were scaled and centered prior to analysis
