Resighting probability
The average resighting probability estimated with CJS model was higher with CV+HSV than with CV in both species. In CV and CV+HSV, respectively, resighting probability was 0.05±0.01 and 0.19±0.02 inA. junius and 0.05±0.01 and 0.06±0.01 in R. multicolor . The effect of sex on resighting probability was revealed with CV+HSV but not with CV in A. junius , showing higher resighting probabilities for males than females (Fig. 2a). This sexual difference was not observed in R. multicolor (Fig. 2b).
