Resumen:
The Two-banded Plover (TBPL, Charadrius falklandicus) is a little-known shorebird endemic to southern South America that breeds along Patagonian coastal areas. Our aim was to estimate nest survival and explore breeding site fidelity in two beaches: Playa Paraná (PP, 42°47?S, 64°56?W) and Playas Blancas (PB, 42°42?S, 64°33?W), both located in Chubut, Patagonia, Argentina. We monitored nests and collected data across four breeding seasons (2012, 2015-2017) to analyze models of nest survival throughout the estimation of the Daily Survival Rate (DSR) and the potential influences of covariates (i.e. clutch size, nest age, the distance of each nest to high tide and to the nearest road). We also captured and banded 24 TBPL adults during 2016 season, and in 2017, we conducted resightings surveys with binoculars and cameras to identified banded adults. Model selection indicated that the best fit models included a site effect on the DSR of TBPL nests (AICc
