Spatial and temporal variation of the austral thrush Turdus falcklandii and its food resources. (A) Thrushes in forests, (B) thrushes in prairies, (C) annelids in forests, (D) annelids in prairies, and (E) fruits in forests. Mean variation curves (solid lines) and 95% confidence intervals (dashed lines) were obtained after performing spline cubic routines with 10,000 bootstrap replications, respectively.
