Migrating curlews on schedule: departure and arrival patterns of a long-distance migrant depend on time and breeding location rather than on wind conditions

Table 1 GLMMs comparing migration parameters, and wind variables between curlews departing from and arriving at wintering sites. Boxplots illustrating the differences are shown in Supplement 1
