Breeding Biology of the Fork-tailed Storm-petrel Oceanodroma Furcata on Kasatochi Island, Aleutian Islands, Alaska
Bibliographic record
Abstract
We present the first detailed account of breeding biology in Fork-tailed Storm-Petrels Oceanodroma furcata from the Aleutian Islands, Alaska, where nearly two thirds of the global breeding population occurs.We examined timing of breeding, breeding success, chick growth, parental provisioning and chick diet during two consecutive breeding seasons at a colony in the central Aleutians.Most adults laid eggs before late May, eggs hatched between mid-June and early August and chicks began fledging in mid-August.Timing of breeding varied between years, with an earlier mean hatch in 2005 than in 2006.Hatching success was consistently high in both years (89% in 2005, 91% in 2006), but fledging success varied substantially between years (58% in 2005, 89% in 2006), indicating that factors that influence chick survival may drive annual breeding success.Visitation rate, meal size and composition of chick diets also varied between years, suggesting that foraging conditions varied during our study.Food availability and weather conditions may both have contributed to the variation we observed in timing of breeding and fledging success.

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; a candidate call from one teacher head, not a consensus.
