ARRIVALS

Each row, taken together with the related EVENTS row, represents an arrival or departure of an individual from the observation conducted during a follow. The related EVENTS row must be an arrival event; it must have an EVENTS.Behavior value of ARR. This related EVENTS row supplies arrival and departure time values, and the ROLES role related to the event supplies information on the individual arriving and departing. For further information see the documentation of the EVENTS table.

This column may not be NULL.

A boolean, whether or not the related participent, related through EVENTS and ROLES, was in a nest at the time of arrival. This column may not be NULL.
