AGE RATIOS AND RETURN RATES OF ADULT MALE OVENBIRDS IN CONTIGUOUS AND FRAGMENTED FORESTS
Bibliographic record
Abstract
We determined proportions and return rates of yearling and older territorial male Ovenbirds (Seiurus aurocapillus) in 12 forest fragments and two contiguous forest sites in southern Ontario to test the hypothesis that a larger proportion of second-year birds occupied forest fragments. There was no significant difference in the proportion of yearling birds among small, large and contiguous forests (small, 54.0%; large, 54.3%; contiguous, 44.9%). Return rates did not vary among fragment size categories (small, 34.4%; large, 35.7%; contiguous, 42.8%). Males in small fragments did not differ significantly from those in large fragments or contiguous forest in mass, wing length, or a condition index. Males also did not vary in these characteristics between age groups. These results suggest that male Ovenbirds in our study area do not occupy sites in proportion to their quality as breeding locations.

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.
