Nocturnal Flight Activity by Northern Gannets <i>Morus bassanus</i> in Response to Predator Presence
Bibliographic record
Abstract
The Northern Gannet Morus bassanus typically flies only during the day, with minimal flight activity following civil twilight. Here we document nocturnal flight activity by Northern Gannets in response to predation risk by Eastern Coyotes Canis latrans. Eight parental gannets were fitted with GPS/time-depth recorders on 15 July 2021 at mainland nest sites at Cape St. Mary’s, Newfoundland, Canada. Previously, among 506 foraging trips in 2019 and 2020 that were investigated using biologging, only two were initiated at night, suggesting nocturnal departures for foraging are very rare at this colony. Then, however, killings of chicks by coyotes occurred within our study plot on 24 July 2021. From 24 July to 20 August 2021, we recorded 51 instances of nocturnal departures from the colony during which individuals rested on the water overnight and returned to the colony by the following morning without foraging, which we deem to be a response to predator disturbance. The predation and nocturnal anti-predator flight behaviour recorded in this study is indicative of the risks associated with mainland nesting by colonial seabirds.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
