  1. For each modelled set of covariates is given the number of parameters (Npar), the total deviance explained and AIC relative to the best model (highlighted). Capitalised parameters are linear, those in lower-case factors. Models are listed in descending order of complexity and all include four re-encounter parameters (ptd*sex, see text).
