a

The study plot Waterford in Connecticut was excluded from analyses due to small sample size (n = 1).

b

Global probabilities were calculated using the parameter estimates and SEs from the top-ranked combined model (nest depredation modeled as a function of latitude and nest age, nest flooding as a function of maximum high tide, 1% exceedance value, and serial date) based on the covariate values for each study plot. Date and nest age were held constant at the mean values observed (nest age = 13 days; serial date = 188).

c

Local probabilities were calculated using study plot as the sole predictive variable in models of daily nest depredation, flooding, and survival.
