Table 1 Beta regression models on nocturnal departure timing (proportion of night at departure) for (a) all birds, redstarts (n = 14) and robins (n = 21) and (b) birds departing during the first night after capture, redstarts (n = 6) and robins (n = 7)

From: A quasi-experimental approach using telemetry to assess migration-strategy-specific differences in the decision-making processes at stopover
