A Capture–Recapture Model with Double-Marking, Live and Dead Encounters, and Heterogeneity of Reporting Due to Auxiliary Mark Loss

摘要: Capture–recapture (CR) models assume marked individuals remain at risk of capture, which may not be true if lose their mark or emigrate definitively from the study area. Using a double-marking protocol, with main and auxiliary mark, both live encounters dead recoveries large scale, partially frees CR this assumption. However, fall off its presence is often mentioned when are reported. We propose new model to deal heterogeneity detection uncertainty an in multi-event framework. Our general model, based on uses information physical captures/recaptures, distant observations animals. applied our 13-year data set harvested species, Greater Snow Goose. obtained seasonal survival estimates for adults sexes. Survival differed between where upon recovery was ignored versus those accounted for. In framework, no longer biased because due estimation rates.
