Behavioural plasticity in the early breeding season of pelagic seabirds - a case study of thin-billed prions from two oceans

Table 2 Effect of colony and sex on timing of arrival and pre-laying attendance patterns during the pre-exodus phase of Thin-billed prions Pachyptila belcheri from the Falkland Islands and Kerguelen

Dependent	Independents	F	P	Effect size

Significant p-values (P > 0.05) are marked bold. As a measure of effect sizes, we report partial Eta-Square values (η²). None of the interactions were significant (N = 50 birds)
