  4. The success of the best-fit model for determining nest attentiveness status of adult Common Terns during the breeding season on Poplar Island by time of day. Nest attentiveness status was compared against paired video data to determine accuracy, allowing classifications of True On (bird was correctly assigned as on the nest), False On (bird was assigned as on the nest but was actually off the nest), True Off (bird was correctly assigned as off the nest), and False Off (bird was assigned as off the nest but was actually on the nest). Status determinations occurred at randomly selected minute(s) during a bout
