From: Migration departure strategies of shorebirds at a final pre-breeding stopover site
Departure headings of Eurasian Curlew (a), Great Knots (b), Bar-tailed Godwits (c), Godwits departing before 15 May (d) and Godwits departing after 15 May (e). Black dots outside circles show departure direction of each flock, while the rose diagrams inside the circles show the distribution of individual departure direction. Arrows are the mean directions of all individuals. Light green sectors (light blue for menzbieri godwits in c–e) are the orientation range if birds fly following a rhumb line towards the breeding ground; orange sectors show the orientation range if following a great circle route (buff for menzbieri godwits in c–e)
