Table 5 Coefficients, stated as effect size (SE), of generalized linear models of great egret capture rate (Rate) and capture efficiency (Efficiency). The top model of Rate was selected using corrected Akaike’s Information Criteria (AIC_c). The two top models of Efficiency were selected using corrected quasi-AIC (QAIC_c).

*Best model. Model selection based on models with ΔAIC_c < 2; Appendix 1 and models with ΔQAIC_c < 2; Appendix 2.
^a BSL = Sloughs Adjacent to Burns, dSB = days since burned, D*Hab = interaction of depth and habitat, Δ = difference of AIC_c value between best model and the given model.
^b Models of capture rate use a gamma distribution and capture efficiency models use a quasibinomial distribution. Models of capture rate are (capture rate + 0.01) = (explanatory variables) because zeroes cannot be log-transformed.
