Individual early breeding season chronologies of Thin-billed prions from the Falkland Islands (N = 35) and Kerguelen (N = 15). Color bars show the timing and duration of the subsequent phases from arrival to the colony (first yellow block) until the end of the second foraging trip in incubation (marked in grey) or earlier recapture (marked with #). Colony attendance before the pre-laying exodus consisted of shifts of 1–9 days in the burrow (in yellow) alternating with foraging trips of 1–13 days (in turquoise), followed by the pre-laying exodus (in pink). After return from the pre-laying exodus, the birds spent 1–16 days in the burrow (in yellow), followed by a first foraging trips (marked in green). In 2010, 1 of 10 of the males at New Island showed some egg neglect (marked black), lasting for a single day (the birds left one night and returned the subsequent night)
