Fig 1.
Map showing the geographical context of the study system, the breeding and wintering ranges of the target species and the migration routes for anexemplar individual of American white pelicans (AWPE).
Elevation is shown in 100 m bands from <100 m (pale grey) to >1500 m (dark brown). Radio-tracked positions for an exemplar individual are shown as back triangles.
Table 1.
List of environmental variables included in quantile regression of hourly speed of American white pelicans (AWPE).
Table 2.
Circular correlation coefficients between the flying direction of the American white pelicans and the encountered wind direction at each given recorded location.
Results are shown for each season using the complete dataset and three different speed thresholds.
Fig 2.
Results of the quantile regression analyses of the hourly flying speed of AWPE for each season and each of the environmental predictors considered.
Each black dot is the slope coefficient for the quantile indicated on the x axis. The red lines are the least squares estimate (solid) and its 95% confidence interval (dashed). The grey area represents the 95% confidence interval for the quantile regression estimates plotted as the black line.
