Table 3 Candidate weather models formulated to explain variation in the timing of departure among autumn-migrating dabbling ducks in Illinois River valley, as detected by weather surveillance radar, 1995–2009, ranked by ascending Akaike’s Information Criterion (AIC). We included YEAR as a random effect in each model. wi indicates model weight and K indicates number of parameters used in each model
