Example of how behavioural classifications included in dataset O_VLIELAND can be used to study time budgets. Time budgets are shown for five individuals in September 2018, which is the non-breeding season when birds were present in intertidal areas on or near Vlieland. The time when birds are foraging shifts every day by 0.5-1.0 hours, as the moments of low tide shifts with the lunar cycle.
