Timing of departure and landing for eurasian hoopoes (red) and great reed warblers (blue), separated into long (> 4 h, solid lines) and short flight bouts (< 1 h, dashed lines). Shown are the cumulative frequencies of departures in relation to dusk and landings in relation dawn. Y = 1 indicates all birds have departed, Y = 0 all birds have landed. Beginning and end of the night (darkness) are derived from the tag’s light sensor. The light shaded area marks an hour before and after darkness, the darker area marks the night
