dc.description.abstractAdult survival, an important fi tness component, is usually 1) lower in lighter individuals due to their reduced ability to survive winter conditions compared to heavier ones, especially in resident species at northern temperate latitudes and 2) lower in females compared with males due to higher reproductive costs incurred by females. In this paper, a capture – mark – recapture dataset of 649 cetti ’ s warblers Cettia cetti ringed seasonally at two wetlands in central Portugal over an 11-yr period (2000 – 2010) was modelled in a multi-state framework to examine the infl uence of these individual covariates on apparent adult survival, while controlling for the presence of transient individuals in our study area. Th e probability of change in mass state ( ψ Light → Heavy , ψ Heavy → Light ) during the annual cycle was also estimated. Overall, birds survived better during spring – summer (breeding/moulting periods) compared with autumn – winter, but there was no eff ect of body mass on apparent adult survival probability. Th e modelling detected a signifi cant interaction between sex and season, in which resident females survived better than resident males in spring – summer ( φ RF 0.857 0.117 and φ RM 0.698 0.181) while the opposite pattern was found in autumn – winter ( φ RM 0.440 0.086 and φ RF 0.339 0.084). In addition, cetti ’ s warblers had a tendency to lose mass in spring – summer ( ψ Heavy → Light 0.560 0.063) and to regain mass in autumn – winter ( ψ Light → Heavy 0.701 0.069). Th is pattern of body mass change during the annual cycle may refl ect energetic costs to reproduction and moulting, and/or a response to increased starvation risk during winter. High body mass, however, did not increase adult survival in this population presumably due to the relatively mild winter weather prevailing in central Portugal. Survival estimates are more likely to be explained by important ecological and behavioural diff erences between the two sexes in polygynous passerines. Our results highlight that studies aiming to identify the main factors shaping survival and individual fi tness in polygynous species should be conducted during diff erent phases of their annual cycle.por
