Resumen:
We describe the breeding biology of the Yellow-browed Tyrant (Satrapa icterophrys) in a native forest of central eastern Argentina. We monitored 23 nests during three consecutive breeding seasons (2015?2018). The breeding season lasted from mid-October to late January and all nests were built in native tree species. Modal clutch size was 3 eggs, incubation period was ~15 days and nestling period lasted ~16 days. Daily nest survival rate was 0.96, and the cumulative probability of nest survival in a nesting cycle was 26%. Our data contribute to the knowledge of the life history traits of south temperate bird species. As the Yellow-browed Tyrant only nested in native trees close to temporal or permanent water bodies, we highlight the importance of preserving this type of native habitat which is under threat as a result of overexploitation and development.
