Fig. S3: Parameter estimates of a Cormack-Jolly-Seber model estimating biweekly survival and detection probability of radio-tracked little owls in Germany between 2009 – 2011, assuming that supplementary feeding affected survival in all seasons. Mean.phi are survival probability intercepts for summer [1], autumn [2], winter [3], and spring [4], and ‘beta’ are parameter estimates for the linear predictors of body mass (mass), and supplementary feeding during the nestling phase (feed, , for summer [1], autumn [2], winter [3], and spring [4]) on survival probability.
Table S1: Seasonal survival probabilities of radio-tracked little owls in Germany given as the median and 95% credible interval of survival estimates derived from a Cormack-Jolly-Seber model. Because the model accounted for sex, size, winter severity and supplementary feeding, survival estimates are provided for all possible parameter combinations. Food supplementation was provided during the chick-rearing period only, for details see (Perrig et al. 2017)
