The population structure and habitat use of resident of Mandarin Duck (Aix galericulata) in Wu River (Southwest China)

Table 4 Logistic regression results for the final set of habitat models of Mandarin Duck (Aix galericulata) during post-breeding period. Used sites were coded as 1 and available sites as 0. K is the number of parameters in the model, logLik is the log-likelihood estimator, AICc is akaike information criterion for small sample sizes, Δi is the difference in AICc value from that of the best model (i.e. the lowest AICc), and ωi is AICc weight. Except for the global model and null model, only models with Δi < 2 are shown
