From: Individual consistency in migration strategies of a tropical seabird, the Round Island petrel
Dates of migration departure and arrival to/from the breeding colony (Round Island) of adult Round Island petrels tracked for more than one migration. Dates of the same individual are connected by vertical lines, and individuals are ordered from left to right by increasing mean date for departure and arrival, separately (therefore, individual one for departure is not the same as individual one for arrival). Filled circles are coloured by the petrel year (i.e., 2009 = 2009/2010) in which the departure or arrival took place. Grey shaded areas represent the austral summer
