Fig. S1: Parameter estimates of the Cormack-Jolly-Seber model estimating biweekly survival and detection probability of radio-tracked little owls in Germany between 2009 – 2011. Mean.phi are survival probability intercepts for summer [1], autumn [2], winter [3], and spring [4], mean.p are detection probability intercepts for periods with full effort [1] and reduced effort [2], and ‘beta’ are parameter estimates for the linear predictors of winter snow cover (win), sex (male), body mass (mass), and supplementary feeding during the nestling phase (feed) on survival probability, and for the linear predictor of winter snow cover on detection probability (p.win).
