Appendix A. Two tables of competing model structures of detection probability (p) of adult and first-year wheatears.

TABLE A1. Multistate mark–recapture models ranked by ΔQAICc to determine the best covariate structure of adult detection probability (p). Survival (phi) and transition (ψ) parameters were held constant while modelling different structures of p. Subscripts denote variables used in the models: no subscript = constant across groups and time, trt = experimental treatment (fed or control), sex and year.

Table A1

TABLE A2. Mark–recapture models ranked by ΔAICc to determine the best covariate structure of first year detection probability (p) of wheatears determined to have fledged successfully. Survival parameters were held constant. Subscripts denote factors used in the models: no subscript = constant across groups and time, nest treatment (nest_trt; fed parents or control parents), juvenile treatment (trt; fed or control), year and presence/absence of color rings (col).

Table A2

¹ Subset of juveniles with known experimental nest treatment (parents fed or control) because parent ID could be confidently determined. Includes juveniles with metal rings (with/without color rings), that were assumed to have fledged or observed/captured after fledging.

² All color-ringed juveniles that were observed/captured after fledging, including those of unknown nest treatment.
