Modeling the effect of heterogeneity and time on survival and initial proportions of two categories newly encountered individuals wandering albatross at Possession Island.

The candidate models vary in the presence/absence of heterogeneity on survival (σ) and of temporal trends on survival and proportions (π). For all models breeding and success probabilities were state dependent and constant, and encounter and state assignment probabilities were state and time-dependent. For each model the deviance (dev), rank, AIC and ΔAIC are given. Subscripts h and s refer to heterogeneity and state, respectively, T to a linear temporal trend and T+T2 to a quadratic temporal trend. def indicates rank deficiency.
